AXA Bike Rear Light

Manufacturer: AXA
Type: K980

Description of failure

The rear light has a storage capacitor (also called supercapacitor) which ensures that the rear light on the bike remains illuminated when you stop.

Failure investigation

As the light continues to work, it is reasonable to assume that the supercapacitor is defective. The capacitor can then be replaced (1 F, 5.5 V, RM 20). As the housing usually no longer closes tightly after opening, you should consider gluing it.

Reichelt order number for the supercapacitor: KO DCL5R5105HF
(Note: The replacement component is a big bigger than the original one. But bending the contacts a little bit, works fine.)
