Hello all. I've noticed in recent years that speed pedalecs "german ones" in particular, that is, come with an integrated brake light. I think this feature would be a good addition on my own bike, which is not a speed pedalec but a standard 250w Bosch powered bike. The problem is I am not aware of a kit with the necessary wiring and switches needed to install such a feature is readily available on the market, if at all. I see aftermarket kits online but they look bulky. I'm looking for something that can be integrated into the existing wiring system.
