Why Volkswagen Polo Brake Lights Not Working

Burnt-out brake light bulb

The most common reason for a brake light not working is a burnt-out bulb. To check if this is the case, look at the brake light bulb in the rear of your vehicle. If the bulb is blackened or there is no filament visible, it needs to be replaced.

Faulty brake light switch

The brake light switch is a small switch that is located under the dashboard. When you press the brake pedal, the brake light switch closes and sends a signal to the brake lights to turn on. If the brake light switch is faulty, it may not be able to close properly and the brake lights will not turn on.

Faulty brake light wiring

The brake lights are wired to the car’s battery and to the brake light switch. If there is a problem with the wiring, the brake lights may not turn on. To check the wiring, you will need to use a voltmeter to test the voltage at the brake light bulb.

Faulty brake light fuse

The brake lights are protected by a fuse in the car’s fuse box. If the fuse blows, the brake lights will not turn on. To check the fuse, you will need to remove it from the fuse box and look for a break in the metal strip.

Other causes

Other causes of a brake light not working include:

A problem with the brake light relay
A problem with the brake light module
A problem with the car’s computer

If you have checked all of the above causes and the brake lights are still not working, you should take your car to a qualified mechanic for further diagnosis.
