Aftermarket headlight

[mocles]

My senada e-bike has a front headlight that has a horn inside and I like to replace it with something brighter that has a horn. I tested out the leads on the new light and found which wires do what but when I hook it up to the three pin weatherproof connector on the bike nothing works. Anybody have any ideas?

Maybe the new light draws more power than what the bike will allow for?
Dunno.

If you can’t get it to work, there are some fantastically bright aftermarket headlights you can buy and attach which charge independent of the bike via USB.
