After getting tired of the wimpy high beam on my Ducatis, I decided to upgrade to the PIAA Extreme White H1 bulb. The H1 replaces the stock high beam bulb on the following models:
- ST4S (2001-2003)
- Gran Canyon
Simple plug in design that is identical to the stock plug and shape. This bulb draws the same wattage as the stock high beam, but puts out the equivelant of 110 watts. The light color is 4000K, or white in the range from blue to Yellow. The stock bulb puts out a light that is 3200K in color, so the PIAA is much whiter. This light will be brighter than you’ll need for your nighttime riding.
