Xtreme White Plus 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.
Xtra Technology
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
Performance - Xtra technology produces better color contrast and depth perception allowing drivers to see farther.
Technical - One-piece filament and heat-resistant quartz glass ensures dependable, consistent performance.
Style - Xtreme white color output with crisp illumination for the HID look.
