I'm a big fan of Rigid's stuff. Not the cheapest, but very good, consistent output, selection of patterns, and small housings. A lot of other guys now have lights with similar output, but I'm not sure anyone can meet the same output in the size housings that Rigid makes.
Best prices I found are here:
I use the Rigid website (rigidindustries.com/
) to look at the technical specs, then use the search function on the power-sports website to find the part there. There website is not very browsable for lighting for some reason, but the price is right and their customer service is excellent.
