Just ordered my Optronics housings and 2 bulbs. A 20W Energy Saver in 8* spot, and a 20W 15* spot. I ordered from bulbs.com which has a $19.95 minimum order, so I threw in some uber low beam bulbs for my truck along with the order. If I'm going to be on the road after dark, be it bike or truck, I want to see and be seen!
