I'm now heading into my 3rd year on the same Sylvania SilverStar White Light halogens. Prior to installing them, I dreaded riding at night and always made every effort to arrive home just prior to sundown.
After installing the SilverStar White light halogens (and adjusting the beams somewhat higher), I no longer worry about night time riding. They made a HUGE difference and were well worth their cost.
Most Hayabusas arrive with their low beams directed excessively low, which is useless for anything other than looking for your keys at 20 feet away.
The SilverStar White Lights I use are stock wattage, so there's no charging system or electrical issues to fear, and there are no legal issues to fear as they are stock wattage. The SilverStar White Light's are brighter than the Cool Blue's.
