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!

It's possible the green is a data wire. The light might start in low by default and be looking for a change state to switch to high.

Oh! That is an angle I didn't consider. I'll start looking into possible signals I can send. Thanks!
