The most common cause for your brake lights staying on is the switch in the foot brake pedal. If it comes loose or is broken. Check the brake pedal assembly, if it has come off it will be hanging about by it's wires or may just be loose. It's a normally closed switch which means it works the opposite way round to a normal switch. IE. ON when not operated and OFF when operated. The brake pedal normally sits against the switch which keeps the circuit open and hence the lights are off. When you press the brake pedal, the switch is released, circuit is closed and the brake lights come on.

Check the brake light switch. It's under the dash, connected to the brake pedal. If it's adjusted wrong or faulty, it could cause the brake lights to stay on. If you can use a meter and tell that the brake light switch is ok, next test the turn signal switch. Sometimes they short out and leave the brake lights on. You'll have to pull the steering wheel to do that.

Why do the brake lights stay on in a ford escort?

I would check and make sure that you have the right light bulbs installed. For your brake lights, it may take a double filliment bulb. If you put a single filiment bulb in, the lights will remain on all the time. If your bulbs are correct, i would double check the stop switch which is right above the brake pedal. My 1994 requires 1157 bulbs for brake lights, and 1156 for everything else. (Reverse, Signal) Worst case scenario is that your master cylinder or brake booster is not holding adequate pressure, and is allowing your brake pedal to sag lower then it should, thus making the car think you are pressing the brake. Hope this helps!

Any information about a 2005 Ram 2500 that the running lights keep coming on and kill the battery when the vehicle is off?

Are you sure it is your running lights & not just the brake lights? A bad brake light switch (common problem) will cause your brake lights to stay on all the time because they are not wired to the accessory switch, meaning they will work whether the truck is on or off. Hope this helps!

1990 Nissan hardbody brake lights stuck on?

Why would the brake lights on a 1998 Ford Escort LX stay on?

There is a round piece of soft plastic that sits on the inside of the hardware that controls the brake pedal arm. A white piece directly across from this piece apparently activates or deactivates the brake lights. This blue piece of plastic pushes in that white piece enough to make the brake lights go off. This blue piece has broken down over time. Now, if I can just find a replacement part...

Your brake light switch is faulty. It is very difficult to fit the new one as it is a one shot switch (1 chance of putting it in properly).

Why would rear parking and brake lights stay on when the car is shut off?

There are two or more faults at work here depending on the car. If your car has a relay that runs brake lights or Tail lights one or both could be bad. OR If your car has these items controlled by a body control module it could be bad or with this system the computer grounds the bulbs to make them work and damage to the wires anywhere in the car can cause this. OR You have a brake light switch that keeps the brake lights on all the time AND a bad ground in the system so the Brake lights ground through the tail lights. This kind of thing is more common on per 2000 model year vehicles.

Why is it your brake lights and side lights come on when you brake with out the ignition on on a Honda accord?

You do not need the key in the ignition to make lights work. They are "hot" all the time. The reason you Sid marker lights are coming on at the same time is because you have a bad ground in one of your brake lights. It's allowing electricity to jump from the brake lights to the tail light circuit. Take the brake lights apart, clean up all the rust and make sure they "ground" to bare metal. Problem cured.
