Be careful with those 100W bulbs. They can burn your reflector very quickly if your wiring harness does not give up first.
That's very good advice. When I put mine in, I let her idle for ten minutes or so on high-beam, reaching up under the fairing to check for any hot spots in the the wiring or reflector. Nothing got even slightly warm. But I'll continue to keep an eye (or hand) on it for awhile yet.
By only upgrading the hi-beam, it's not as much of an issue because you don't use it as much, whereas the lo-beam is always on.
I think I'm going to install two bullet-type driving lights under the fairing, and aim them up and off to the side a little, so they point into the curves when your'e leaned over. Mount a switch on the handlebar to reach it easily. A little trick from the 24-hour endurance racers...
