One of the most critical components of your car when it comes to night driving is the lighting system. So, let’s talk about your vehicle’s brake lights and headlights now.

Make it a habit to always check all of your lights before driving your car, even if the brake light is located in a hard-to-see place. As a result, you should be aware of the critical nature of your brake lights. Brake lights may not be working for you as a driver at one point or another.

What Causes That Brake Light Doesn’t Work When Headlights Are On?
Brake lights may not be working, but headlights are. You may be unsure of what is going on. Having a problem with simply your brake lights can be an odd one. The first thing we need to discuss is why this is happening. It is possible that your brake lights are not working, but your headlights are still on.
1. You Might Have A Problem With Your Electrical Ground
There may be a problem with your brake light switch, which could lead to a poor electrical ground, if your brake light isn’t working. Damage to the wire ends may be the cause of an inadequate electrical ground. A loose connection or rusty wires can also be the cause of the problem. Using a jumper wire, you can verify that the connection between your light switch and a good ground is correct. Then, you must apply the brakes.
Brake lights may indicate an issue with your electrical ground if they work. It’s time to fix the ground connection.
2. You Might Have A Problem With Your Light Switch And Fuse Box
Your light switch and fuse box may be faulty. You must first find your vehicle’s fuse box or power distribution center (PDC). You may find the PDC or the power distribution center in the engine compartment. Under the dashboard, you’ll find the fuse panel.

Brake lights can be affected if your fuse or switch box is malfunctioning. In addition, see if a fuse has blown in the circuit. The only way to fix it is to buy a new one. The type of replacement you choose should be the same as the one that blew. If you’ve replaced all of the fuses, it’s also important to know why one blew. Keep it from happening again by solving the problem.
3. You Might Have A Problem With Your Turn Signal Switch
Some automobiles have brake lights that are also part of the turn signal circuit. Brake lights may not work properly if the switch is broken in this way. As a result, you’ll need to inspect the switch diagram’s wiring for damage.
4. You Might Have A Problem With Your Light Bulbs
When your brake lights don’t work, but your headlights do, this is a common cause. The bulbs in your house may have burned out. If only the other lights are out, but your brake light doesn’t function, try replacing the bulbs. Take the screws out of the bulb lens to check it. Through the trunk, you’ll be able to find and access the bulb lens. Check your vehicle’s repair handbook or owner’s manual if you need help locating the bulb lens.
Once you’ve found it, you’ll need to push the bulbs and counterclockwise turn them. This will remove it from the socket. It’s imperative that you replace any blown or darkened light bulbs with new ones. You must use the same type of light bulbs every time you replace them.
5. You Might Have A Problem With Your Wiring
Wiring problems might cause faulty brake lights to fail. You should inspect the brake light switch and fuse panel for loose or damaged wires. The wires that link the switch to the bulb sockets must also be checked.
