Can't get the light working on 36v bike. Help :)

[Aleksei Consvich]

Hi,

I have this ebike about 2 years now, a while ago I straight swap the original front light with an upgraded version rated 12-80V, all good. Recently I upgraded the controller with an bluetooth one and I can't get the lights working for a reason I can't yet figure it out, I have 13v in my lights circuit. Any help is appreciated.

Is the bulb/LED ok? Maybe replace it with another one (like a 6-24V model)?

Hope you have sorted out the the problem now? Your new controller may be supplying lights with reverse polarity of the old controller, best to check polarity with meter if you can.
