Faulty LED(s) in the high-mounted brake lamp:

Individual LEDs (Light Emitting Diodes) in high-mounted brake lamp are combined into groups of up to 3 LEDs and are supplied with power as a group.

If one LED should fail, the other LEDs will be loaded even more and will fail soon.

If one LED group is faulty (3 individual LEDs), the legally required brightness set forth by the Economic Commission for Europe it still met.

If more than 3 individual LEDs are faulty, the legally required brightness will no longer be meet and the high-mounted brake lamp must be replaced.
