Busch & Müller μ Taillight

The μ (‘mu’ which stands for ‘Micro’) is smallest taillight that is legal in Germany—meaning it provides full visibility. It features an aluminum housing, powerful LED and a standlight.

The μ comes with two mounts: one attaches to your bike’s rear fender, the other to the seatstay. The light pivots on its mount, so you can place it anywhere on your fender and still orient it correctly. The μ is not grounded, so you need to run two wires to the generator (not included) that powers it. It does not incorporate a reflector—it’s a truly minimalist light.
