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!
In my opinion bicycles should not have a high beam, but here goes:
Look inside, do any components look fried?
Can you get the led to light by applying the a low voltage with a current limiting resistor directly to it? If I don’t know what to do with the circuit I would probably go outwards from the desired results.
This is StVZO-compliant light, i.e. has a sharp beam cutoff.
Tracing the circuit was my first thought. It would be difficult to open the housing non-destructively. Even if I could open the housing, getting it back together and restoring its IP rating would be sloppy at best.
Yes, the low beam works starting at ~7V with the negative and positive supply attached as pictured.
