Installation is simple, worked without issue (scars Dynamo). When I wanted to turn on the light when it is raining again after 4 months, went nothing more. Pear in front buckets, behind also. It is futile if the defect has destroyed the front of the rear light or vice versa. Spare parts there is no, so buy a new taillight. Convincing taillight is therefore not ... But there is no really an alternative ....
