There is a version of the spotlight with an external charger, Pure designation without "B". If is not specified in item description, this possibly leads to a bad buy, as in my case. In the daily flood of information, can be such a thing overlooked very fast times. To replace the battery or batteries, the lamp needs to be opened and that is quite fiddly. The locking bolts with slot can not turn without an additional tool. Incomprehensible why such a well-known manufacturers such as Busch & Müller has created no more user-friendly way here. Also, there are apparently two different bracket versions. A clip with a screw holder and. Even in the operating instructions is displayed with the clip, was gefliefert the other. In general, the clip bracket is displayed as an article and picture. While you can remove the headlight from the screw holder, but the handlebar bracket remains on the bike and could be easily stolen by a third party. The clip mount is of course much more comfortable. The set is not worth the money. If, then you should invest the few euros for charging socket and greater luminosity in addition.
