Common brake light problems that not everyone knows
Brake lights are an important part of the car safety system, to notify other drivers of location and intention to stop. Below are some brake light problems that few people notice.
Dim or weak brake lights
If your car's brake lights look dim or weak, they may be old or dirty. Check and clean them regularly to ensure they are bright and clear, or replace the bulbs if the problem persists.
No light when braking
A common problem can be a faulty brake switch. The brake switch activates the brake lights when you press down on the brake pedal. If it is not working properly, the brake lights may not come on.
Brake lights stay on even when not braking
Conversely, if the brake lights stay on when you are not pressing the brake pedal, it may be because the brake switch is constantly energized. This can result in the false impression that the brake pedal is being pressed and the lights will not turn off.

Flashing brake lights
Brake lights that flash instead of staying on when you press the brake pedal can be a sign of a problem with the ABS controller or sensor system.
Flickering brake light system
If you're having trouble with all of your brake lights flickering instead of staying on evenly, it could be a sign of a problem with the power supply or wiring circuit.
Brake lights on tail lights not on
If only one or both tail lights do not illuminate when you press the brake pedal, it may be because the bulb has burned out or the lights are not set correctly.
Light bulbs must be replaced regularly.
If you have to replace your brake lights frequently, this could be a sign of a problem with the electrical system or it could be due to poor quality bulbs.
Therefore, to ensure driving safety, it is very important to maintain and check the brake lights regularly. When a problem occurs, the car should be taken to a professional auto repair shop for inspection. Do not ignore any signs of brake light failure, as it can affect the vehicle's braking ability and increase the risk of an accident.
