Parking lights turn on by themselves — Dodge Pickup?

  • The lights turn on when the parking lamp relay is energized closed. That happens when the FCM supplies a ground to the relay coil (power is always applied at both the relay coil and output contacts – just need a ground). The BCM tells the FCM, via the PCI data bus, parking lights are selected and your switch gets the whole process moving.

Why do my parking lights stay on when car is off?

Parking lights are important for keeping everyone safe on the road, but you don’t need them all the time. If the engine is off, the parking lights will drain the battery, so they should be used only when necessary.

How do I turn my parking lights off?

In most cars, parking lights are incorporated into the headlight switch. Your parking lights can be switched on and off by turning your car’s headlight dial – usually one flick between completely off and on.

What is the purpose of parking lights?

Purpose of Parking Lights Drivers used them when they parked their cars at night on narrow, poorly lit roads. Having parking lights meant other drivers could see the car and help avoid accidents. On a modern vehicle, parking lights car also help other drivers see the vehicle, but there is less need for them.

Why my park lights wont turn off?

If your parking lights stay on when your car is off, you might just need to hit the parking light switch. This switch controls whether or not the lights are on- even if the key is not in the engine. All you need to do to fix this problem is to flip the switch. Your parking lights will shut off right away.

Will parking lights drain battery?

Parking lights (Standlicht) are one low-wattage bulb in one headlight and one low-wattage bulb in one tailight – (left or right side, depending on which way you set the blinker stalk. Parking lights can be lft on for many hours – at least over night without draining the battery.

Where are the parking lights on a car?

Parking lights are located at the front and back of your vehicles; they are white or amber in the front and red on the back. All of them must be visible for 500 ft. It is never legal to drive with your parking lights on; they are only to be used during parking.

How long do parking lights stay on?

The parking lights are designed to be left on overnight. There shouldn’t really be any need to use them during the day. More modern cars have LED lights that could be run for a very long time. They might also switch off the lights if the battery level gets too low.

Are parking lights a legal requirement?

When should I use parking lights? According to the Highway Code (section 249) all vehicles are required to display parking lights when parked either on a road or in a lay-by on a road with a speed limit greater than 30mph.

Do you ever use parking lights?

Technically, they’re right. Section 24800 of the California Vehicle Code states: “ No vehicle shall be driven at any time with the parking lamps lighted except when the lamps are being used as turn-signal lamps or when the headlights also are lighted.”

Why does nobody use parking lights?

Unless you are in a designated parking spot, you are legally required to display these lights. The reason for this law is safety. At night, it can be hard to see a vehicle that is stopped or parked. And stopped vehicles in unexpected locations cause accidents.

Why are my car interior lights staying on?

Lasting Light. If the car interior light simply won’t turn off, then check the switch. It may have gotten bumped accidentally by a passenger, valet or car wash employee. If the switch is in the “door” or “off” position and your interior light still stays on, then you should consult a mechanic.

Why are my dash lights staying on?

On some cars the lights stay on for like 30 seconds after the ignition is off. But if they are on all the time even when the light switch is fully off, something is wrong, that is NOT normal. That happens sometimes due to somebody wiring some accessory to the nearest hot wire, which might be the dash lights wire.

Why do headlights come on by themselves?

The vehicle may be having issues with the headlight circuitry. This may mean that the sensor, photocell, body control module, replacement headlight, or a fuse/relay has failed. Something is allowing power to be sent to the headlights when the vehicle should be off.

Parking Lights Stay On When Car Is Off

Parking lights are necessary for everyone’s safety on the road, although they are not required all of the time. The parking lights will deplete the battery if the engine is not running, thus they should only be used when absolutely required. The question is, what should you do if the parking lights refuse to turn off. The first thing you should do is repeatedly flick the headlights switch to check whether it returns to normal operation and turns the lights off. If that doesn’t work, try pulling the relevant fuse or totally disconnecting the battery to prevent the battery from draining while you try to resolve the problem.

Why Are Parking Lights Important?

You may use parking lights to safely highlight the location of your car on the road when driving in low-visibility situations such as night, snow, rain, fog, or snow. Because of a breakdown, you may find yourself stranded on the side of the road with your vehicle partially or completely stuck on the asphalt. In cities, street and building lights, as well as a large density of slow-moving traffic, make it difficult to see your car; nevertheless, when driving on a country road, it is even more difficult to see your vehicle at night.

As a result, you should switch to the parking lights, which will give enough lighting to make your car visible without obstructing the view of oncoming traffic.

How Do You Engage Parking Lights?

It is unusual that parking lights are used, and some drivers are not even aware of how to use them. When it comes to turning on parking lights, there are two major methods:

  1. Adjusting the location of the headlight switch to the first setting
  2. Setting the turn signallever to activate the left or right ride sight parking lights
  3. Turning on the turn signallever.

Depending on the car, such as the earlier Mercedes-Benz, the headlight switch may have 5 different positions: the left indicator; the right indicator; the off; the parking lights; and the headlights. The configuration varies depending on the make and model of your car, but in general, the controls are connected to the headlight switch or lever.

How to Disconnect the Parking Lights

In the event that you were in a rush to leave your car and realized that the lights were still on, it’s possible that you accidentally struck the turn signal lever or simply flicked the headlight switch once. Make a second trip to the automobile to ensure that everything is in the proper location. I realize that you’ve most likely already done this, but it happens to everyone, so it’s wise to have it on the list just in case. As a precaution, if the headlight switch is not functioning properly, toggle it repeatedly until the parking lights turn off completely.

2. Pull Out the Fuse

Pulling the parking lights fuse will cause the circuit to be broken, and the lights will no longer receive electricity. It is necessary to identify the fuse box, which may be found behind the steering wheel or within the engine compartment, as the first step in the process. You may use the owner’s handbook to assist you in locating it, since you’ll also need to consult it in order to identify the appropriate fuse or relay.

Every car has a unique fuse arrangement, so examine your owner’s handbook to ensure you’re using the correct one. It may be combined with the headlights fuse, or you may have to take them both out in order to turn off the lights completely.

3. Disconnect the Battery

Disconnecting the battery is the most easy method of turning off the parking lights’ electricity supply. Lift the hood and use a wrench to detach the battery, starting with the negative terminal (the black wire) and working your way up to the positive terminal (red wire). Obviously, this will prevent you from using the car, but because you need to address the parking lights issue before continuing to use the vehicle, this shouldn’t be a problem.

How to Repair the Parking Lights

The procedures described above will prevent your battery from draining, but they will not address the problem. If we want to accomplish this, we can address two sections that are within the realm of what a do-it-yourself technician can accomplish: we can replace the relay and the headlight switch. It is beyond my ability to repair anything else, and you will need to speak with a mechanic or an electrician for assistance.

Replace the Relay

The most difficult aspect of changing the relay is determining where it is located. In certain cars, the lights relay is located exactly next to the fuse box, however it may be found anywhere below the hood, generally towards the borders and the front mask. The location of certain relays is difficult to pinpoint since they are positioned within one headlight and then fork off to the other. As a result, I can’t tell you where to look for them with any accuracy. The quickest and most straightforward method of locating the relay is to consult the owner’s handbook or conduct an internet search depending on the brand and model.

Install the replacement relay and determine whether or not the problem remains.

Replace the Light Switch or Lever

Headlights and parking lights are controlled by a switch that can be either a standalone switch or one that is built into the turn signal lever. The procedure for removing the switch varies widely depending on the type of vehicle, as well as the brand and model. I’ll give you two examples to give you a sense of what to expect, but the specific processes may vary depending on your situation.

How to Replace the Light Switch

It is possible that the light switch is held in place by a couple of screws, in which case you will need to remove the bottom plastic of the dashboard. Some, on the other hand, can be removed by finding the “sweet spot” and pushing the switch, which will remove the entire assembly from the socket. Simply swapping either individual components or the switch in its entirety, reconnecting the power wire, and plugging it back in is all that’s required after that.

How to Replace the Light Switch Lever

The method of changing the light switch that is built into the turn signal lever takes some technical knowledge, but it is not difficult to complete at your house. The only equipment you’ll require are a set of screwdrivers and, if you’re lucky, a couple of starorhex keys. Remove the shroud that covers the steering wheel column to uncover the screws that hold the turn signal lever in place. It is possible that you may need to remove the steering column tilt lever in order for the shroud to come off.

Simply unplug the power cord, unscrew the old lever, and screw in the new one to finish off the job. It is necessary to change the light switch and the turn signal lever together when the light switch and the turn signal lever are merged.


Fixing a defective light switch is relatively difficult, but if there is an issue with the wiring, you’ll need to seek expert help to complete the task. While the information in this article should be sufficient to resolve nearly all of your parking light issues, there are some additional considerations to keep in mind.

electrical issue.parking lights.

I have a 2004 Ram 2500 Heavy Duty Cummins with the exact issue that you have described. The parking, roof marker, and license plate lights will not turn off when the switch is turned off. I removed the light switch and used a multi-meter to check for shorts, after which I dismantled the switch and checked the contacts for damage. I couldn’t discover any shorts, but the contacts appeared to be in good condition. After that, I reconnected the light switch and unplugged the parking light relay from the circuit.

  1. After that, I rebuilt the relay, reconnected the batteries, and checked the lights.
  2. Neither the parking nor roof marker lights, nor the license plate lighting were turned on.
  3. I was under the impression that the problem had been remedied, or at the very least recognized (maybe a sticky relay).
  4. I turned off all of the lights and turned off the car’s motor.
  5. I then removed the parking light relay and fuse from the circuit.
  6. I double-checked the wiring schematic and performed some further reading on the internet.
  7. Originally, it was intended to be installed on each side of the Fuse Box, underneath the hood.

According to reports, the module will cost little more than $200.00 and will need to be programmed to your truck’s VIN number by your local dealer. I believe that I will schedule an appointment with the dealer for the following week. I hope this information is useful in resolving your issue.

In AZ it’s illegal to drive after dark with onlypark/foglightson. Also in AZ your headlights are suppose to be turned on 1/2 hour prior to sunset. Newer cars with the automatic headlight turn on feature should have a rheostat switch to adjust for sensitivity and be adjusted to come on as soon as dusk starts which is about 1/2 hour before total darkness.

Quote:Originally Posted bygreg42I’ve wondered about that.Lights on in rain is a law these days in a number of states (including here in PA as well).Although how it distinguishes between just wiping the windshield for a sec and having the wipers on would be a good trick.I was driving a Chevy Cruze as a rental over the past several days and don’t think it’s auto lights are that sophisticated.I think in general the basic auto headlight systems just assume that the DRLs are enough to cover the rain bit.Although that doesn’t really fit when the DRLs are not the headlights.Just to follow up with this, I was driving the Cruze again this morning with a lot of rain.So I tested out that whole wipers on, headlights on setup.And it DOES work in this car.I guess the GM system has trickled down to all of their cars.Basically there’s a delay of about 15 seconds.If the wipers are on that long, the headlights will come on (as documented by the now-standard indicator on the dash).If the wipers are on for shorter periods the lights will stay off, or stay in DRL mode I guess is what it really is.Big problem in my mind is still that it makes people overly complacent and dumb.”Oh, you mean this car doesn’t do it automatically?”They’d be saying that even when it’s dark outside and they can’t see.

Quote:Originally Posted byMerc63Fog lights, properly aimed (i.e. factory ones, especially since they are usually fixed) cannot be an annoyance or hazard to others, as they don’t shine upwards at all. They spread out low, that’s the point. If you are getting annoyed by a set, then they are driving lights or they are misaimed due to being aftermarket and poorly installed or due to crash damage.I LOVE the sanctimonious overreacting by people on this board.Wrong. Ever had a Dodge pickup, Audi, Subaru or any of the other rigs that have overly-bright STOCK fog/auxiliary lights on coming at you the other way? They are indeed an annoyance and a hazard to other drivers.Here in Oregon, incorrect fog/auxiliary light use is punishable by a fine of $287. By ‘incorrect’ I mean that according to the law, fog/auxiliary lights should be used the same as high beams, as in turned off when an oncoming vehicle is within 500 feet. Headlight beams must be dimmed when following another vehicle within 350 feet, according to the manual.Furthermore,In normal visibility conditions, fog or auxiliary lights should be turned off.Anyone who claims that fog/auxiliary lights ‘illuminate the ditches to show wildlife’ is full of it. By the time these lights illuminate something, it’s too late.Turn fog lights off unless it’s foggy. Simple as that.As for your comment about over reacting people, illegal fog/auxiliary light use is a big problem. Over-reaction? I think not.

Simple as that.As for your comment about over reacting people, illegal fog/auxiliary light use is a big problem. Over-reaction? I think not.My DODGE pickup has those STOCK auxiliary lights only able to be used while LOW beams are on. I heard it’s something about only being able to have 4 lights on and high beams count as two on each side. Makes sense to me! So, at night with no traffic I use my high beams as they cover both far and wide.When there are cars around I use my regular low beams with the stock “fog” lights. The low beams alone don’t cut it with all the deer we have here in eastern MD. The auxiliary lights go out wide and low. I can see eyes in the fields a good bit away. Far enough that I can react if I start seeing them bouncing towards the road. Just as important, they alert me to the deer I know are there because over here where there is one there are more. And they can be on the other side of the road. And during the rut they don’t think.The lights also light up that section closer to the truck so I can see objects in the road which could be a hazard and I have time to adjust my positioning a little so my tires don’t get slashed. Might be hard to do at 65 MPH but it isn’t very hard to do at 40.They also help when making turns. I’ll be able to see any pedestrians that are too occupied with their cell phones aimlessly starting to cross the intersection as I’m turning into it. Regular low beams on my truck and eco box roller skate just don’t cover those spots.BTW, I’m not full of it. They do help.As far as blinding people, well I have a little eco box compact as well and I’m never blinded by any trucks coming the other way with their “fogs” on. Usually if I’m blinded by fogs it is someones self installed, un aimed driving lights on an older vehicle with dimmed headlights.BTW, I would get flashed a good bit after I installed my lift and tires but then I aimed my headlights and my truck is not blinding anyone at all. I’ve not been flashedin a long, long time. That is unless I forget to switch the high beams off BY ACCIDENT when using them.

Quote:Originally Posted byKenningtonsIs that legal in your state? It isn’t here.Yes! These are stock “auxiliary” lights. They are mounted in the bumper and aim low and wide and do not interfere with oncoming traffic. Actually, Dodge has it rigged so they can only be used with the low beams or parking lights. If the high beams are switched on, the auxiliaries automatically shut off. They come back on when the highs are switched off. It is my understanding that the legality is the number of lights which is limited to 4. The lows are one on each side and the auxiliaries are one on each side as well, adding up to 4 and being legal. Ones the highs are switched on, another headlight turns on, adding up to four, so any other forward lights must be turned off. Here we have to turn our highs off as well with approaching traffic as well as if following. I can’t remember the exact distances. I think those rules are pretty standard though.Aftermarket “off road” lights which a lot of people mount higher up on brush guards or roll bars are not legal for street use.

Parking lights: how do they work and what are they for?

Your automobile almost certainly has sidelights installed – and they must be operational as well in order for your vehicle to be considered roadworthy in the eyes of the law. Parking lights are frequently the same lights as traffic lights, however they must be exhibited when a vehicle is parked on the side of the road. Sidelights are intended to increase the visibility of your vehicle for other road users, especially at night or in low-light conditions such as tunnels or wooded areas. They are often used at dusk or in low-light conditions such as tunnels or wooded areas.

  1. The top ten finest automobiles for the winter of 2022 You can see more clearly behind your vehicle when you turn on the sidelights, which also activates your number plate lighting and rear lights, allowing other drivers to see you more readily as well.
  2. The display of lights on one side of the model is only possible on the side that faces the road.
  3. Parking lights, on the other hand, are sometimes controlled by a separate switch.
  4. Their name comes from the fact that they are always on, and they imply that your automobile will always have a light on no matter what – however many models just have them on the front of the vehicle.
  5. LED daytime running lights (DRLs) have been used by several manufacturers as a distinctive technique to make their models stand out from the competition.

How do I use parking lights?

If your car was manufactured prior to 2011, it is likely that you will have to manually switch on the sidelights of your vehicle. Begin by starting the car’s engine and making sure the transmission is in neutral (or ‘Park’ if it is an automatic), and then getting out to see if the sidelights are on or off. If they are, turn the car off and back on. It is necessary to turn either the lighting-column stalk or a selector knob on the dashboard (which is normally located above your right knee) to the point halfway between off and dipped headlights if they are not already in this position.

In order for this function to be activated, the lighting control switch must be set to the ‘automatic’ position, which is often indicated by an illuminated ‘A’.

In accordance with the Road Vehicles Lighting Regulations 1989, sidelights must be on at all times throughout the hours of darkness, which are defined as the half-hour before sunrise and half-hour after sunset.

When should I use parking lights?

According to Section 249 of the Highway Code, all cars must have their parking lights on when parked on a road or in a lay-by on a road with a speed limit greater than 30 miles per hour. Because leaving parking lights on for a lengthy amount of time on quicker routes can drain the car’s battery, it is not practicable to park on faster highways at night for extended periods of time. On roads with speed limits of 30mph or less, you are not required to switch on parking lights if your vehicle is parked in an approved parking space or lay-by that is at least 10 metres from a junction, near to the curb, and facing the flow of traffic.

In addition, the Highway Code instructs vehicles not to park on the side of the road in fog unless it is absolutely necessary, and to leave their parking lights on in this scenario.

Parking lights and the MoT

It is a legal requirement in the United Kingdom that all automobiles driven on public roads have a complete set of functioning sidelights. Therefore, any vehicle submitted for its yearly MoT test (from its third birthday onwards) will fail if any of the front or rear sidelights or number plate bulbs in the vehicle are not functioning properly. We recommend that you follow ourMoT checklista few days before your car’s test since changing a bulb yourself is typically a very inexpensive and simple activity that may spare you from receiving an unexpected cost from the garage.
