- There is no way to fix the melted connector. It must be replaced with a new one. The replacement part is called a pigtail and they’re available at any auto parts store. Just ask for a new headlight pigtail connector for your particular vehicle. You’ll also need a crimping tool, crimp connectors, wire cutter/stripper and heat shrinkable tubing.
Why did my headlight connector melt?
Most of the time, the issue is caused by the OE wire gauge, which is too small (typically 20 gauge) to handle the current drawn by the headlight bulbs. In other cases, the issue is the result of loose terminal connections, which can cause resistance in the circuit and lead to overheating.
How do I change a headlight wire socket?
Replacement sockets come with a small stretch of pre-trimmed wire.
- Disconnect the negative terminal from the battery with a socket wrench.
- Disconnect the existing socket from the headlight assembly and then remove the bulb.
- Cut the wires going to the socket about 3 inches from the fixture using a wire splicer.
What causes a connector to melt?
Once a wire gets hot, the heat can travel along the wire until it gets to an electrical connection, such as a plug in a wall socket. Once the connections in the plug get too hot, they melt and expose bare wires. These ultimately cause a short circuit, which produces more heat and melts the plug connection.
What is a headlight pigtail?
A headlight socket is a female connector for a headlight bulb that acts as a power supply for the bulb. The headlight socket consists of a female connector designed to work with bulbs, attached to a pigtail of wiring that hooks up to the car’s electrical system.
How do you check a headlight connector?
How to Check That Power is Getting to the Headlights: Use a Test Light
- Unplug the light bulb electrical connector.
- Turn on the headlights.
- Connect your test light to a good ground and touch the test light probe to the power side of the connector terminal.
How much does it cost to replace headlight wires?
The wiring may be damaged over a period of time. It can cost you $100 per hour. The reason behind the problem may be a faulty headlight switch. Often times, if the headlight works only on high beam or low beam, the dimmer switch may have broken.
What is a splice connector?
A splice connector is a vinyl plastic wire termination device that has a sharp metal insert which safely cuts through the plastic insulating jackets of two wires and crimps them together.
Repair melted headlight connector
Many automakers have resorted to undersizing the wiring of headlights in an attempt to save money.Melted low beam headlight connections are one such example. Headlight connections are melting as a result of the undersized wiring in the vehicle repair sector, which is producing significant difficulties in the industry. This occurs when the wire is too tiny for the present load, resulting in overheating, which causes the plastic connection to melt. As an added bonus, corrosion on the terminals generates high resistance, which in turn can cause the temperature to rise to the point where the headlight connections are melted.
Fix for melted headlight connector
The melted connection cannot be repaired under any circumstances. It must be removed and replaced with a new model. The new part is referred to as a pigtail, and it may be found at any automotive parts retailer. Simply request a new headlight pigtail connection for your specific car. a new headlight pigtail connector for your specific vehicle. Along with a crimping tool and crimp connections, a wire cutter/stripper and heat shrinkable tubing will be required.
Install new headlight connector
However, it does not important whether or not the wire colors on your replacement headlamp connection match the colors on your present connector. Simply make sure that the wires leading to each terminal are the same length. Remove the old connector by cutting it off. Then remove approximately 12′ of insulation from both the new pigtail and the old wires. Before you crimp the new connection, slide the heat shrinkable tubing onto either the new pigtail or the old wire and heat shrink it. After the crimping is complete, slip the tubing over the splice and heat it using a heat gun or lighter to shrink the tubing to the proper length.
Add ceramic extenders for added protection
Normal manufactures ceramic plug-in extenders that attach to the headlamp and are capable of withstanding higher temperatures than the standard pigtail. You may find out more about them here. Rick Muscoplat posted a blog entry on
More Than One Way to Melt a Headlight Harness
Written by Ryan Kooiman Have you ever disconnected a headlight bulb in the middle of what you thought was a regular headlight bulb change only to discover a melted connection beneath the bulb? This is a scenario that technicians confront on a daily basis, whether they’re working on an Acura, BMW, Chevy, Ford, Volkswagen, or any other make or model in between. A common source of the problem is the wire gauge employed by the manufacturer, which is often too tiny (typically 20 gauge) to accommodate the current required by the headlight bulbs.
In some cases, the vehicle may be equipped with a ‘upgraded’ bulb, which, depending on the use, generates significantly more heat than the original bulb.
Before, the only option accessible to technicians was to replace the connection with one that was comparable to the one that had failed previously.
Obviously, this is not the most pleasurable repair because the technician has to drive his car out the door and hope that the repair lasts as long as the original connection did.
A Solution That Prevents Melting

This is a predicament that technicians come with on a daily basis, whether they’re working on an Acura, BMW, Chevy, Ford, Volkswagen, or any other make or model in the middle. A common source of the problem is the wire gauge employed by the manufacturer, which is often too narrow (typically 20 gauge) to accommodate the amount of current used by the headlights.

Before, the only option accessible to technicians was to replace the connection with one that was identical to the one that had malfunctioned previously.
- Wire of 14 gauge is used for greater conductivity. When using the ‘Plugplay’ option, you can connect a harness between the factory harness and the replacement bulb. It is possible to utilize the harness as a pigtail if the original connector is melted. Coverage for the following high-temperature bulbs: H1, H3, H4, H7, H11, 9004, 9005, 9006, 9006XS, and 9007
- H3, H4, H7, H11, 9004, 9005, 9006, 9006XS, and 9007
The installation of one of these harnesses is strongly suggested when changing a bulb if the existing harness has not been damaged. This will help avoid a future problem from occurring.

Causes of melted connector on H4 lamp for headlight
The question has been seen 22k times. We’ve received sporadic complaints that a headlight on one of our Jettas is not working properly. ECS Tuning has provided each of them with aftermarket ‘eurospec’ headlights and fog lights. They claim to be Hella lights, although it is possible that they are counterfeit. The light was out for quite some time, but I only noticed it today and decided to change the bulb. The bulb was withdrawn and I discovered that the connection was somewhat melted at the low beam ground terminal (the one between the two parallel side terminals), but that both filaments appeared to be in good condition.
The lights are back on, but I’m still perplexed as to why.

- If the connection is loose, the resistance will rise, resulting in much greater heat. The majority of the time, a loose connector is the source of the problem
- However, a loose connector is itself caused by an overheated bulb. So, if you believe that all of the automobiles that have complained had a loose connector, you would be correct
- Nevertheless, I do not believe that this is the primary cause. Using a bulb with a much greater nominal wattage is something that most people do
- Nevertheless, using a 55watt headlight instead of a conventional 35watt headlight is usually accepted by the wiring system, however this is dependent on other characteristics
- Inexpensive bulbs have a greater resistance than predicted, inexpensive bulbs generate more heat
- You may test the resistance of the bulb using an ohm meter. You might be astonished by what you find! Bulbs must have a 2 ohm resistance
- If they are 2 ohm with a slight increase or decrease in resistance, there is nothing wrong with your bulb
- Instead, look for the major cause. However, if they are greater than 3 ohm, this is the case! However, if your bulb resistance is about 2.7, it may aid in the loosening of the connector, and the two of them combined might melt the connector. In the absence of any air ventilation, bulbs generate heat, which needs to be dissipated somehow
- Some bulbs contain heat sinks, others do not. A heat sink and a cable connecting it to the connection are included with certain kinds of h4 bulb, and I encourage using these types of bulbs instead of conventional variants. However, the old-fashioned bulbs also contain a metal neck, which serves as a heat sink in its own right. In every automobile, there is a small hole on the light box that is intended to circulate the warm air within the light
- Check to see whether these holes are clogged.

While this is not incorrect, I do not believe it is a satisfactory answer. Almost every XJ you come across will have some sort of melting going on at the headlight switch. It’s up in the air whether or not it’s badly planned. In most circumstances, it takes a significant amount of time before anything occurs. The headlights are connected in the same manner as your house lights when they leave the manufacturer. Basically, everything passes via the switch. AMC, which was on the verge of bankruptcy, most likely did it to save money.
- As a result, it accomplished the goal for which it was created: saving the firm money.
- I find it difficult to think that many Jeeps set themselves on fire in the 1980s; otherwise, they would have amended the law by now.
- Yes, the switch is the very minimum necessary to support the weight of the headlights, but it is necessary.
- When I claimed they would catch fire, I wasn’t kidding.
- I was fortunate in that I was on the ball and was able to put mine out before it became too serious; however, others have not been so fortunate.
- Additionally, it is fully functional and plug & play.
- Purchasing a pre-made harness is not required, but there are a few popular ones available from Putco and other manufacturers.
If you like, you may also create your own.
Despite the fact that I haven’t replaced my headlights yet, the harness I put together will really sustain more than 300W of light since I utilized 10awg for the power feed to each of the filaments.
Returning to your initial question, there are still plugs available that will function properly.
I’ve also seen them simply replaced with insulated spade terminals (female, 1/4′), which work just as well.
In addition, some suggestions for Googling.

- Are you certain it’s completely melted and no longer a liquid?
- For the repair, if you can locate an electrical contractor who is willing to redo the pin for you, you may be able to get it done for a reasonable price.
- Dealers, on the other hand, are more likely to just replace the complete wire harness and charge you for the service.

Bulb Socket Melted! what to do now?
first posted bygot0azn0rice on the internet so My right headlight socket had completely melted! After a while, the light bulb will not turn on any more. Has anyone else had this issue? How much did it cost to get it repaired? Are you referring to the back cover or the electrical connector? I believe you are referring about the rear cover, and I believe you are wrong. It can become stuck at times. If it has indeed melted, what wattage lights are you using to illuminate it? The expense of repairing plastic is high; you have two options: fix it yourself with jb weld and replacement components, or buy a whole new headlamp.
If you’re referring to the connection socket (the little rectangular piece that snaps into the metal bulb plug connectors), then the problem is either a wiring fault or inappropriate bulbs, as previously mentioned.
If you’re referring to the socket on the rear of the headlamp that contains the wire plug, which is neither round nor rectangular, you’re correct.
The three items about which I’m attempting to determine what you’re talking about are as follows: the wire connection for the headlights the connection for the low-beam bulb the rear dustcap for low-beam lamps
Melted headlight connector – BMW F800 Riders Forum & Registry
- s03-28-091 When my low-beam headlight went out right before I brought my bike in for the cutting out problem, I was furious. That was a five-week ordeal since the vehicle was at the dealer. The good news is that the cutting out appears to have been resolved. But then my lowbeam went out again, came back on for a few days, and is now permanently out of commission. The fault was discovered when I opened the back cover. The connecting harness had entirely melted and was no longer functional. On my F650CS, I experienced the identical issue. The connection for the low-beam light would continue to melt. I would remove the melted connection and crimp on a new one to replace it. only to have it fall apart after a month or two of purchasing it. This appears to be a stupid thing to be dealing with. The first time the bulb was replaced, I was concerned that the dealer had not made a secure connection between it and the circuit board. increasing the resistance at the connector and, as a result, increasing the heat dissipation at the connector Is this a frequent issue, and if so, what might be done to avoid it?
- s03-29-092 The fact that this is the first time I’ve heard of it suggests that it is not frequent at all, in my opinion. Perhaps someone else can weigh in on whether they agree with or disagree with my point of view.
- s03-29-093 You have four items to look at, any one of which might be the source of your problem. You’ve got a major problem if you have any two of them. 1-Does it have a standard-wattage bulb fitted in the lamp? 2-Is the bulb securely fastened in position to ensure proper heat transfer, or is it only loosely fastened? 3-Do the internal female connector terminals of the plug’s internal female connector terminals grasp the male terminals of the bulb strongly enough that it is difficult to push on? The fourth alternative is somewhat less likely, although it is still possible: 4-The bulb is drawing an excessive amount of current. When a bulb’s filament breaks at the attachment point, it may wave around and spot weld itself on recontact, but this will result in the bulb’s total length being reduced. As a result, the light becomes brighter and consumes more energy. Only one who has the ability to see the unseen can do the impossible. A 2009 Champagne F800ST with non-ABS, OBC, HHG, CS, Zumo450, and a Givi E260N tail trunk is for sale at 03-29-094. Someone else on this forum has also experienced a melted connection in the past. However, I am unable to locate the thread. �s
- s03-29-095 The original post was made by batamali Can you please hand that $ it that you’ve been smoking Arles for the past hour? Yes, I am able to. �s
- s03-29-096 Eventually, I was able to chisel away all of the melted plastic, leaving only the exposed metal connection leads. I replaced the bulb with a new one and connected the leads. It appears to be functioning OK for the time being, but I’m not sure if it will continue to overheat and melt apart over the next several days or weeks. As a result, there is no longer any insulating material between the connector leads, which increases the likelihood of items shorting out in the future.
- s03-30-097 That is correct, I merely replaced the bulb with the same one that was working well, so I now have a fried negative and a working positive still in the plastic wrapper. The dealer that looked at it in Pennsylvania when I had a tire put said that I could have a poor ground on the bike someplace, but that because I am out of warranty, there isn’t much I can do about it at this point. and a new wiring harness for the entire bike (since that is the only way to obtain one) costs several thousand dollars. I could acquire one on eBay for next to nothing, but installing it would be a pain. No, I don’t believe so. A tail light unit I had installed would fry the ‘neg’ (if there is a neg on the tail light bulb) on many lights, and then I fitted the steble horn, which also resulted in the neg. being fried on many lights. As a result, I removed it and went back to stock. and then the headlamp, similar to what you have. Nothing has happened since then. Although the parking light has failed, it does not appear like anything has been fried on the vehicle. The original post was made by batamali Can you please hand that $ it that you’ve been smoking Arles for the past hour? Yes, I am able to. �s
- s04-01-098 pepperkorn, Replacement of the wiring harness is not an option, no matter how much money is spent. You may make your own ‘plug’ in the same way that you did. Get a sufficient number of female blade connectors and discard the old ones that have been overheated or annealed. After that, solder or crimp on the new connections. Slip on small pieces of heatshrink tubing that are flush with the end of the terminal and heat shrink them to hold them in position. After that, when you connect the wires to the bulbs, they will be tight and very conductive, but not to one another. Only one who has the ability to see the unseen can do the impossible. A 2009 Champagne F800ST with non-ABS, OBC, HHG, CS, Zumo450, and a Givi E260N tail trunk is available. Just now, I’ve had my personal experience with the connection failure. Mu baby was returned to me yesterday following the completion of the warranty repair. It was revealed that a leaking fork seal had occurred during the 12K service, and of course, I had to wait for the seals to be sent because they didn’t have any on hand. Since they were going to be pulling everything apart anyhow (and it wasn’t a job I wanted to do myself), it was the perfect chance to finally buy the HyperPro springs (which live up to all that has been mentioned about them previously in other discussions) and have them put, but I digress. As I was about to leave the dealership, which was now empty due to the fact that it was after 6 p.m. on a Friday, I saw that the ‘light’ alert had been activated once more. I wasn’t too concerned about it because there had been some strange behavior with the taillight turned on and off during the previous couple of weeks. Indeed, it appeared like the taillight was out once more
- However, a simple twist remedied the problem, and we were back on the road. As long as the high beam indication was still activated, I didn’t thought to check the headlights till later. When we arrived at our destination, I turned off the bike and then turned the key back on, expecting the warning to be reset, but it was still illuminated. As luck would have it, the low beam has been turned on. Of course, I’m cursing myself at the moment. If we hadn’t gone so late, I might have been able to get a replacement bulb from the dealership. But, hey, there’s always Kragen, so I removed the cover from the rear of the light assembly and proceeded to remove the connection from the light. It was quite a surprise to see that the connector had disintegrated into fragments of melted plastic, leaving the connectors hanging loose. My headlights have completely stopped working since the circuit is exposed. The cursing is no longer directed at myself, but rather at a volume loud enough for the neighbors to hear. At the very least, it’s still covered by warranty, so I won’t have to worry about repairing the damned thing. This morning, I went back to the dealership (I didn’t even want to hang out there socially today since I was so tired of it). When I saw how much better the front suspension had improved, I knew I had to go to the canyon as soon as possible and put it through its paces. I’m sorry, I’ve gotten off track. However, those springs are just incredible!) and the service manager is undoubtedly dissatisfied since he can tell that I’m not smiling because I’m not. He’s currently talking to another client, so I walk to his assistant and show her the bits of the fried connection that have fallen off the board. She seemed to be taken aback, stating that she has never seen anything like that before. As a result, she is finally able to inform the service manager of the situation, and he appears even less happy than before, as he now has to inform me that der korporation does not sell that particular item in order to do repairs, but he will investigate further. The diagnosis is that the WHOLE HEADLIGHT ASSEMBLY will need to be replaced (parts are being ordered immediately and should arrive by Tuesday or Wednesday), but I still have no functioning headlights. Not only is there a problem in the possible-fix-it-ticket department, but we appear to be invisible to certain folks even with ALL of the lights turned on as well. In addition to going on the second annual Azusa Canyon Mother’s Day Ride (which is a fairly lonesome event, with only about 5 other sportbikes in the entire canyon last year, and everyone else was probably at breakfast with mom), I’m not looking forward to driving anyplace without lights. Yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes They must have been able to rig something because as the service manager pulled my bike out of the garage area, he turned the key in the ignition and BOTH lights came on. until a couple of hours later, when we were at the most treacherous parts of Trabuco Canyon. Although, the high beam is still operational, which means that hooliganism will undoubtedly be the rule of the day for tomorrow, and der korp will take care of the headlight issue
- However, I must admit that I am quite concerned about the future and the moment when the warranty expires However, at that time, I’ll most likely be riding a new 1000RR. So, what exactly is the speed of darkness?
- The original post was made by batamali Is it possible for you to pass that $ it you’ve been smoking in Arles? Yes, I can. The bulb itself, or the poor grasping contact of the female terminals, would ordinarily be towards the top of the list of potential villains, if we were to think about it theoretically. It is clear, however, that there are additional electrical gremlins in other sections of the bike, which strongly suggests that the weak ground is the one issue that they all have in common. The most serious consequence of a weak ground (a poor and/or corroded connection) is that the system voltage will vary erratically. That causes mayhem throughout the system, as seen by lights that burn out much too frequently and electric starters that occasionally misfire or falter, among other things. I’m going to presume that there isn’t an LCD display fault that states ‘Poor Ground’ on the screen somewhere. The failure of the headlite assembly to disperse the 55 Watts of heat appears to be a contributing factor to the problem. Because the same failure has occurred on other BMWs, I believe it is the result of a cost-cutting and weight-saving design defect. Many years ago, the wires that supplied electricity to the bulb were thick, heavy gauge wire, but today’s motorcycles, including Hondas, use wires that are considerably thinner and tougher. Not only do smaller wires produce more heat simply by carrying electricity, but they are also less effective at transferring away the additional 55W of heat generated by the bulb’s white hot filament. It is the headlite assembly itself that constitutes another piece of the heat conductive jigsaw. It must be capable of transferring the 55W of heat away from the device to a considerably greater surface area so that it may be transmitted to the surrounding airstream. If the bike is not moved for an extended length of time, more of the headlight assembly’s structural components will become extremely hot. Regardless of whether the bike is moving or simply plodding through the searing Summer heat in gridlocked city traffic, the headlight bulbs attached terminal should never become too hot to the point of melting. NEVER. That’s exactly as it should be. When it came to metal headlight assemblies, this was the way things worked. They are now nearly entirely constructed of plastic, with power and ground wires that are just moderately thicker in gauge. After a certain point, the bulb will overheat and melt the terminal if the bulb retention spring wire no longer pushes strongly on both sides of the bulb’s steel base. The combination of oppressive Summer heat and gridlocked metropolitan traffic creates a major challenge for everyone involved. Remove the negative battery cable’s connection points at both ends and clean them until the metal is clean and bright. Do this for each battery cable. After that, apply wheel bearing oil or water proof grease to the terminal contact interfaces to keep them from becoming damaged before fully tightening them. Check the wire retainer clip on the bulb to see whether it has a lot of retention force. If it is weak as a result of someone’s hasty mistreatment, it should be refunded. I’m thinking of a novel application for a (hidden) piece of braided copper grounding strap connected to the bulb’s base and joined to a disguised, finned Aluminum heat sink salvaged from a PC’s CPU. I’m thinking of something like this: It is necessary to have selective PackRat inclinations as well as the capacity to create new ideas. The end item should/will be inconspicuous and so useful that it will be considered HOT! Only one who has the ability to see the unseen can do the impossible.

- There are no likes or dislikes for the post based on the three series There was a problem with the rear taillights on the e46 before it was replaced with the e90. The connection would eventually fail. To resolve the issue, a secondary ground was connected from the bulb to a good ground. On our motorcycles, I believe you could just connect a ground to the battery. When the back light on my daughter’s car died, I was forced to replace it. The issue looks to be the same as before. We need to get rid of the heat as soon as possible. There is a limit to how much current may be passed across a given wire. It appears that they are only marginally successful.
