I keep thinkin about trying a set of LED fog lights. I found them listed on E-bay. Most of them are rectangular in shape, but if you look hard enough you can find them. I figured LED's would be a good match for the bike because they draw 90% less voltage and amps. Here is a link to a set I think might be a viable option....
