The wiring process involves connecting the brake light to the vehicle’s electrical system, ensuring that the light receives the necessary power to function.
Wiring Components
The following components are typically required to wire a brake light:
- Brake light bulb
- Brake light switch
- Wiring harness
- Fuse box
- Relay (if necessary)
