Inside the machined aluminum housing are the electronics and LED of the Busch & Müller Seculite Plus taillight, which include a standlight. The circuit board mounts to a custom-made stainless steel plate, so it is securely attached. The stainless plate also serves as an attachment for the grounding wire.
The reflector is EN-approved to ensure optimum reflectivity. The light is equipped with ample wire to reach the headlight. The wire itself is a special automotive wire. The insulation is made of a cross-linked polymer with extra-high abrasion resistance.
The light has an M6 thread that screws into a custom-made, two-piece braze-on. Your framebuilder can attach this behind the seat tube of your bike, René Herse-style. The braze-on is pre-mitered for the seat tube, but your builder also can braze it to the end of a tube, if you want to use the light on a rack. You could also mount it underneath the chainstay, Alex Singer-style.
