.
The
additional brake light bulb
M25
uses light emitting diodes (LEDs).
Fault detection and fault display:
Vehicle diagnostic tester
Note
LED failure in additional brake lights (not USA and Canada):
The individual LEDs (light-emitting diodes) in the additional brake lights are comprised in groups of four LEDs and are supplied with current in groups.
The additional brake light is designed so that it can still meet the legal requirements of the ECE regulations (Economic Commission for Europe) should one of the LED groups fail to operate. If a further LED group fails, these requirements are no longer met according to the legislator.
Due to the failure of one LED group, the intact LEDs are placed under increased strain; it must be anticipated that further LED groups will soon fail.
If more than four individual LEDs in the additional brake light have failed, the additional brake light must be renewed (repair measure).
The
additional brake light bulb
M25
cannot be dismantled.
In the event of damage, the complete
additional brake light bulb
M25
must be renewed.
The
additional brake light bulb
M25
is located in the rear lid, above the rear window.
