Rene Herse Taillight


A taillight that matches the aesthetics of a beautiful custom bicycle, combining classic aesthetics with modern functionality. The Rene Herse taillight uses the reflector as its lens, which creates a nice, diffuse light. This reduces the glare for riders following you closely, yet it is no less visible from a distance. The reflector provides a fail-safe in the unlikely event that the LED stops working.


  • This taillight requires a dedicated braze-on (included). It cannot be attached to a bike that does not have a braze-on for the taillight.
  • The taillight is designed to be powered by a generator hub. It does not have its own power source (batteries).
  • The taillight uses the frame/fork/rack as the return to complete the electrical circuit. Anodized headsets, thick paint and powdercoating don’t transmit electricity – sand off  the coating from a headset cup, rack tab, etc., to expose the metal and create a conduit. Carbon components don’t conduct electricity, so they need a bypass wire to complete the circuit.

Made in the USA. 2 year warranty.

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.
