Xtreme White Plus is PIAA's best-selling technology. These H1 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

  • Highest quality quartz glass and alloy filament for better performance and durability
  • 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
  • Longest life with DOT/SAE Compliant
  • One Year Warranty

Satisfied with Purchase
William Witt | March 5th, 2013
Bulbs certainly improved vision on high beam over the stock OEM bulbs. Cannot tell much difference on low beam.

I went back to these after purchasing the ION Yellow. The yellow burned out in a month, but these bad boys definatley come through with a strong white/blue mix and they have lasted me close to a year now. Great investment!

Very easy to install but they are not white at all. Though they are not as yellow in color as the stock light bulbs but they are not that bluish white that i was expecting. They aren't even white. They are whiter but you can tell that there is a yellowish tint to them.

Interesting that some peoples are not lasting. Just used a cloth to instal so i would not touch them. Lasted me now 2 years at the least. They bright bulbs, and I want the ion yellow for DRL. Very happy with their output.

These bulbs are ok if you like the stock look of your lights right now. Absolutely no white or cool blue look. I found a set of bulbs from luminics that looks blue like HID and work just as well for half the cost.
