Reasons Why Brake Lights Don’t Work: A Comprehensive Guide
There are several reasons why brake lights may not be functioning properly. In this section, we will explore some of the most common causes, including:
Loose or Faulty Connections
One of the most common reasons why brake lights don’t work is due to loose or faulty connections.

To resolve this issue, it is recommended to check the connections and clean or replace them as necessary.

Faulty Brake Light Switch
Another common reason why brake lights don’t work is a faulty brake light switch. The brake light switch is responsible for sending an electrical signal to the brake lights when the brake pedal is pressed. If the switch is faulty, it may not send the signal, resulting in non-functioning brake lights. To resolve this issue, it is recommended to replace the brake light switch with a new one.
