A bit of googling this morning has taught me a lot. It looks like one of the best ways to go about this headlight change is to:
1) Swap out the current headlight bucket to something more modern that uses a standard H4 bulb.
2) Get an LED H4 bulb to go in the new bucket.
I searched on hondatwins to see what guys have done, and there doesn't seem to be much if anything on LEDs (unless their search is bad which is quite possible). But, I did find a cheap H4 bucket here:
H4 Chrome Side Mount 6&1/4" 6.25" Head Lamp Headlight Assembly
I'm still searching on LED H4 bulbs. There appears to be quite a few. Suggestions are welcome.
