>>1711411Two of my bikes run SON hubs and B&M lights. One of them supplements the dynamo lights with battery-powered lights on the rack and on the stem mounted where the reflector used to go. The Linus-branded front battery powered light is weak though, I want to replace it with something that looks the same but provides useful light. I also have some Light & Motion USB rubber band lights that I take along on any ride where there's even the shadow of a chance I'll be out after dark.
