Why brake lights and turn signals are not working

In most cars, the same circuit is responsible for giving power to the brake lights and turn signals. Once the turn signal gets faulty, it is very possible the brake light will fail as well.

Once the turn signal becomes faulty, it is possible that the lower brake light will not function. However, it is possible that the third light will still function.

This is due to the fact that both systems (turn signal and brake light) are using the same circuit. When the turn signal switch is faulty, it may prevent the brake light from functioning.

If there is a broken wire in the switch, it will interrupt the lower brake light, and it may not work. However, it may not affect the third brake light because it does not flash with the turn signal.

If you notice that your turn signal and brake light stop function, it is advisable to take the vehicle to a mechanic and get it fixed.

The circuit that is connecting the two systems together can be fixed. You may also choose to check your car’s manual.
