I wondered if anyone had a solution for mounting taillights using just the belt clip. You'd think it would be simple to attach it to the mounting bands attached to seat bags or some cycling jackets (Endura Gridlock). However these thin straps consistently measure at approx. .5mm and the clearance for the clip is 5.0 mm. This amount of "slack" causes the light to rotate right off the thin fabric strap. The taillight I'm referring to is the Nightrider Cheery Bomb. I've tried taking up the slack with old inner tubes, but it's still not secure for a long bumpy ride. I have a large Jandd seat bag and Trek oval seat tubing (2008 trek 6.5), so a seat post/seat tube mounting is not practical. Any thoughts?
