12V Lighting Circuit-ver. 3
I designed this to add a 12v lighting system to a DIY ebike quadcycle. I wanted it to incorporate standard auto relays for reliability, and allow for connectivity with most ebike or motorcycle handlebar controls.
Starting with an inexpensive ebike/atv handlebar control, I then got a cheap LED ebike/motorcycle headlight, turn signals and brake/night lights. There is also a terminal for an additional button or ebike lever for brakes.
For ease of design, there are 4 leads that need to be soldered. Just solder a wire or jumper wire to any M1 to its corresponding M2.
For ver.2 I added the horn circuit and in ver.3 I added hazard lights control.
