Fixing a faulty program bulb is easy. Just remove the backing, unplug the socket from the electrical cable, and change out the light bulb for a new one. If the brake lights are fine, then the issue is the brake lights switch or the fuse.

How to fix the brake Lamp Bulb Fault

The brake lights or lamps ‌on the back of your vehicle help other drivers know when you are slowing down so they can adjust their speed as well.

Since the brake lamps have bulbs, the bulbs will occasionally burn out or stop working.

When the bulb is no longer working correctly or it is not as bright as it used to be, ‌change it out. 

Your vehicle will alert you when there is an issue with the brake lamp. On your dashboard or your console, a message stating a brake lamp will appear.

The reason for this warning is simple: one of the brake lights is not working. It will not tell you which light bulb is not working, and you’ll have to figure it out yourself.

Removing the brake light bulb can be a little tricky, especially if this is your first time doing it. But if you have an afternoon for yourself and YouTube, you can change out the bulb.

Here’s what you need to change out the brake lamp bulb:

  • Brake light bulb – there is no industry standard for brake light bulbs, so there are several kinds of bulbs. You’ll have to use your owner’s manual to look up the type of bulb your vehicle needs.
  • Phillips heads Screwdriver and flathead screwdriver.
  • Flashlight
  • Gloves

How to change your brake light bulb yourself

First, you need to figure out which light is not working. Turn on your vehicle and then turn on the brake lights. Walk to the back of your vehicle and look at the lights. 

One or both of the lights will not light up. When you know which side it is, turn off your vehicle and then open your trunk. 

You’ll have to remove the plastic covers to access the brake light bulb. The carpet in the trunk might be in the way, so you’ll have to remove that first. You’ll need a flathead screwdriver to pry the covers open.

Once the covers are off, remove any bolts or screws that were hidden beneath the covers. 

Now, you can remove the barrier and access the light bulb. How you access the light bulb depends on the make and model of your vehicle. 

Some vehicles, one’s taking off the screws, allow the entire or rear light to be removed while other vehicles just allow the barrier to be taken off and you’ll have to put your hand inside the light to remove the bulb.

Before moving the bulb, disconnect the electrical connector as it still will provide a small amount of electricity to the brake light. 

Now, remove the bulb socket from its mount and unscrew the bulb and replace it. Then place the Bulb and suck it back into the mount. 

Reconnect the electrical connection and then put the brake light back together again. But make sure you test it before you put the screws and the covers back on.

Why do brake light bulbs stop working?

Like all light bulbs, the brake lights eventually burn out of stock price. Most brake light bulbs have a life span of 1 year to 18 months. It depends on the bulb manufacturer.

As the ball gets closer and closer to this replacement date, it will start dimming. You will notice that it is glowing as brightly as it once did. 

Once you notice this, just ‌replace the light bulb. Don’t wait until it burns out. If you drive around without working brake lights, the cops can give you a ticket.

Another reason brake lights stop working is if a collision damages the bulbs. Even a low-speed collision can damage the wiring that provides electricity to the brake lights. 

Sometimes, the damage will not take full effect until a few days to a week later. Bulbs and the wiring that powers the bulbs are delicate. A vehicle does not have to hit you on the rear bumper for the bulbs to stop working.

If you’re in any type of accident, assume your brake lights stop working. Be prepared to change the bulbs or the wiring when you get into a collision.

Does the warning brake lamp bulb fault just mean there’s an issue with the brake light bulb?

Because of the way the warning is worded, you would think that the only issue would be the brake light bulb not working.

However, this warning will appear for several issues. Here are some of the reasons why the words brake light both will appear on your dashboard or on the vehicle status page on your computer’s menu:

  1. The bulb is faulty and no longer working – This one is obvious that we’ve already gone over it.
  2. One of the fuses that are connected to the brake lights is getting old or has blown out – This issue is very easy to fix, as all you have to do is buy a new fuse and change out the old views for the new one. The fuse box will either be under your passenger seat or located around the battery near your engine.
  3. There is an issue with the brake switch – when the driver hits the brake pedal, there is a switch connected to the brake pedal that turns on the brake lights. When the switch is not working, the brake lights will not turn on when the driver applies pressure to the pedal. This does not mean that the light bulbs are burnt. It just means something damaged the brake lights. It will not cost much to replace the brake switch. The cost of the brake switch plus labor will be only $100.


Be sure to turn off your vehicle and disconnect the brake light from its electric cable before you change the boat. You should also wear anti-electrical conduction gloves just to be safe. If the issue is a blown-out fuse or a broken brake switch, both ‌ issues are easy to repair and cheap to replace.
