The headlights and high beams are 90 mm housings. I have found 2 companies that offer LED upgrades. It will take some wiring and such but check out Kaper and Morimoto.
I ordered the Kaper II light fixtures. They are back ordered but will be replacing both the low beam and high beam lights. As soon as I figure out how to get the fixtures out. You can also check out Headlight Revolution to find wire harnesses because the fixtures come with bare wires.
I will post the outcome as I work though my upgrade but this is a place to start.
The LED fixtures you need are L01-0078 low beam and L01-0079 high beam.
Hope this helps.
