For use with any of the Busch & Muller dynamo head lights to wire a dynamo powered taillight. The Toplight Line Brake Plus taillight does not include a wire so one of these needs to be purchased separately. The connectors on the input end will connect to the headlight and the connectors on the other end connect to the taillight. The Secula Plus taillight includes a wire so an additional wire is not needed unless an upgrade to the coaxial taillight wire is desired.
- 185mm/72 inches
