yeah, I'm pretty sure you'll just have to buy a new socket (see the parts list wrightme43 used at the top of this thread) and wire it in. I couldn't tell just by eyeballing it if an H4 socket would fit in the left headlight enclosure, but an easy way to tell would be to pull your right headlight out and see if you can fit it into the left side. I'm at work right now (sans necessary tools) or else I'd give it a try. If you decide to go for it, take some pics and post a how-to. I don't really use my high beam enough to justify the work, but it'd still be interesting to see.
