Wiring H4 halogen bulb.

[Buffalobwana]

I bought some H4 24 v halogen headlights online. No wiring diagram, so wondering if anyone knows which tab corresponds to which numbered wire or which function? What is ground, normal, and high beams? The middle tab is the top of the light.

Thank you!

Don't forget to relay the power, so it doesn't run through the headlight switch.

Can I not just use the stock headlight wires and wire directly to the light? To be clear, these are replacement headlights.

I usually pick up some H4 sockets when I do conversions like that.

You can, it's how the factory wired them. It's also why we lose so many switches.

Ah, I see. Thanks.
