Roxim Z3EK Headlight Wiring (lemmy.world)

I have a Roxim Z3EK bicycle headlight. This light is supposed to have a low and high beam function, but I can only get the low beam to work. So far, I have tried:

  • grounding the green wire
  • sending 12V+ to green
  • sending 12V- to green
  • bridging the green and black wires
  • bridging the green and white wires

I emailed the manufacturer asking for a wiring diagram, but no response.

I appreciate any guidance y'all might have. Thanks!

Where does it normally plug into? If it plugs into some sort of computing device, then yeah, one of them MAY be signal (probably LIN). If it could function with a simple switch however, then as the other said, try every combination possible.
