H4 is the number you are looking for in a bulb with the right tabs on it.. As for the wirinf on other bulbs, you have to play withthem to hit therightspots, although I'm not sure how you get one to stay off. The H4s will take them just about any ay and bothe beams will works, however t get them to work right and have the bright light indicator on when the bright beam is on took some fiddling.
If you colors are the same as mine, I ended up with the red (Ground) on the left looking from the rear, the green on top center, and the blue on the right. Good luck.
