I know their not LED, but I did this
http://www.trademarkmotorsport...s.htm about two years ago when I first got the bike. It's super bright, retains all the stock function and blink rate, and has held up perfectly. It seemed like it was going to be a big pain in the ass, but it took an hour and looked great. I used a small disk on the dremel to cut the lens off some LP flushmounts (mediums I think) and the 3m body moding tape to hold them on, lots of waxes/washes plus a few track days and they have never even wiggled. Anyhow, good job on that guy coming up with it, I love mine.
