The brake light switch is either bad or needs adjusting.

Answerjust because the car stops doesn't mean your brake system is working perfectly, check the brake fluid reservoir and if it is low you might want to have the system checked.

There could be several possible reasons why the brake lights stay on all the time on a 307. The most common reasons would be a bad relay or a bad switch.

why would the lights and the horn stay on all the time just started when the battery was changed

check the brake light switch. located on the brake pedal it may be bad

There is a bushing that the brake light switch rest against when the brake pedal is not depressed. They are known to break. You can get a replacement bushing from any Honda dealer for around $5.00. Just tell them your brake lights stay on all the time and they will know what to give you.

A malfunctioning brake light relay switch will cause your 1993 Toyota Corolla brake lights to stay on all the time. The brake light relay switch is located beneath the drivers side dashboard.

Under the brake pedal is a brake light switch that when you press the pedal it hits it and makes your lights come on..sometimes when they get weak the pedal depresses them simply from the weight of the pedal and they stay on..Have a friend get inside the truck and pull UP on the brake pedal as you look at the lights..if the brake lights go off when they pull up on it..then it is that switch under the brake pedal

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.

Brake lights are on continuously while you are driving. Every time the brake pedal is depressed.

A broken or out of adjustment brake light switch.

At the top of the brake pedal there is a little plastic piece that pushes the switch to turn the brake lights off after the pedal is released. The plastic piece has a tendenacy to fall apart after a period of time. I fixed mine with by replacing it with a 20 cent medal bolt.

Try checking the fuse for the brake lights. If all of your brake lights went out at the same time, this is most likely the problem.

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!

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!

I would check the brake regulator switch, located under the dash near the top of the brake pedal. Its a silver piece that has a button like switch that activates every time you press on the brake pedal causing the light to turn on. It could be stuck in, causing the brake light to stay on.

I'm not a mechanic but I believe that is a malfuctioning DRL module

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.

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).

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...

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.

Brake lights and tail lights. (Unless you have a spotter telling you of course)

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.
