Center Mounted Brake Lamp: Service and Repair

High-Mount Brake Light

• Failure of LEDs in high-mount brake lights:

• Individual LEDs (Light Emitting Diodes) in auxiliary brake lights are combined into groups of up to four LEDs and are supplied with power as a group.

• The high-mount brake light is designed in such a way that it still meets legal requirements when one LED group fails.

• If another LED group fails, these legal requirements are no longer met.

• When one LED group fails, the intact LEDs are given a higher load, by which failure of other LED groups can be assumed in the near future.

• If more than four individual LEDs in auxiliary brake light have failed, the auxiliary brake light must be replaced (repair measure).

Special tools, testers and auxiliary items required

• Plastic wedge (T10039/1)
