PIAA replacement bulbs are the fast, easy way to improve your bike's light output. Simply remove the stock bulb(s) in your headlight, driving lights, turn signals, brake lights, or tail lights, and plug in a PIAA. Using exclusive PIAA XTRA technology these bulbs produce more light without drawing more power.
For example, the H4 Xtreme White Plus headlight bulb draws a standard 55/60 watts (low beam/high beam) yet produces the light equivalent of a standard 100/110 watt bulb. We installed this bulb in a bike and it's nothing short of amazing.
All PIAA bulbs are warrantied for one year from the date of purchase.
