I recently bought the battery powered Busch & Muller toplight. The idea is to be seen in complete darkness and because of the size and the way it spreads light horizontally, allow drivers to judge my distance from them, without dazzling anyone. It also meets German standards, which are apparently enough to qualify it as a legal light. In the event of an accident this gives inattentive drivers and their insurance companies less room to wriggle.
Normally they attach to a full pannier rack, but the Carradice bagman 2 sport has no suitable attachment holes.
So a bodge was needed...
Ah, this painting tray isn't being used!
Chop, chop. Hmm, looks like it might work.
Washers to prevent the plastic bending too much from a point load.
More washers on the underside of the rack. Fiddly to fit, but got there.
Top secured with two cable ties. Possibly need one more in the middle.
Yeah, that should get me seen.
