Durable, dependable and reliable, PIAA Powersports Anti-Vibration bulbs are specifically designed for Powersports to significantly increase bulb life and performance.

By utilizing quartz glass which is stronger than a standard H4 bulb, PIAA’s Anti-Vibration bulbs allow better dissipation of heat. A thicker diameter filament support is fixed to the glass tube allowing the bulb to withstand a large range of motion.

Special features:

– Metal bond holds the heat-resistant glass tube securely to prevent cracks and leaks.
– Welded focus ring and one-piece filament support assures proper position.
– XTRA technology for greater output and performance
– PIAA’s Xtra Technology produces more light with stock power draw
– Engineered to optimize output of stock or aftermarket lights
– White 4000K color provides best color recognition, contrast, and depth perception
– Made with quality components to increase life of the bulb
