When I have the Hi/Lo switch in the Lo position, I get one light on ("Lo" H3 beam). When I have the switch in the Hi position, the "Hi" stays off. The relay clicks over and the "Lo" beam stays on, so I know the relay is OK. When I remove the relay and wire the "Hi" beam directly to the Hi/Lo switch it works, so I know the light and Hi/Lo switch are OK.

I have battery voltage in the "Hi" circuit everywhere up to the 86 terminal on the relay. After that, I get only 0.2v or something. It shouldn't take much current to activate the relay, right? So why dont I get full voltage to the "Hi" beam?

Here is how I have the bike wired:

I should clarify that I'm trying to run one H3 as a Lo beam, and both at the same time as a Hi beam, in case it wasnt clear.

I'm surprised no one even bothered to tell me what a dumbass I was for wiring it that way and expecting it to work. I had the negative side of the relay coil wired to the positive side of the low beam, so the low beam wasn't getting battery voltage.

So I just eliminated the relay altogether and did it this way.

I'm using dual Warn 650 housings with H3 bulbs. Here is a single light pattern ("low" beam).



Compare to the stock H4 low pattern



Not as great as I thought. I figured a light labeled as a driving light would have a wider pattern, but this is more of a spot pattern. Probly should have picked something like a truck sealed beam replacement halogen, or shelled out for Baja Designs halogens.
