H4 XTreme White Plus Anti-Vibration Single Halogen Bulb is PIAA's best-selling technology. These bulbs will provide a brilliant Xtreme cool white light that will light up road hazards and street signs long before a normal halogen bulb. Xtreme White Plus bulbs are engineered for sustained Performance in applications where a high level of vibration and moisture protection is required. PIAA bulbs are engineered with XTRA Technology for greater Performance per watt compared to the competition. XTRA Technology is achieved when a proprietary gas mixture is combined with an aerospace alloy filament that produces greater light output than its rated power consumption: i.e. 55W=110W
- PIAA bulbs are engineered with XTRA Technology for greater performance per watt than any other bulb on the road. Xtra is a term coined by PIAA to designate a high-efficiency bulb that is designed to produce greater light output than its rated power consumption (i.e. 55W = 85W of light output). Greatly enhance your ability to see and be seen. A metal bond holds the heat-resistant glass tube securely to prevent cracks and leaks. A welded focus ring and one-piece filament support assures proper positioning.
- Xtreme White Series of bulbs have a cool white light output that gives the driver better color recognition on depth perception and better contrast than stock halogen lamps
