I've got an old cateye brake light that has a two wire setup just ground and 12v.
What's the best way to hook this thing up to have DRL and brake functions work? I've tried every combination I can think of and can only get one function or the other. What am I missing here?
@MoonDog i have no idea what youre trying to put the light on, but not all lights are compatible with every bike. ive never had luck with 2 wire tail lights, only headlights. Also you may hve just a marker light which sometimes isnt intended to have a run and brake function. might just be a running light.
