My headlights need some serious work. They happen to be the same type bulb as my motorcycle and I've already got a place to buy them (Osram Silverstars). What I'm curious about now is a headlight relay/harness and polishing the lenses. When this really help (assuming good bulbs first of course)? If so, where can I get a good harness and what can I use to polish the lenses with? How hard are the lenses to take off?
