Headlight Bulb Replacement Guide
The Xtreme White Hybrid Bulbs provide the best possible balance between performance and bulb life. Constructed utilizing features from the Xtreme White Plus and Night Tech lines, PIAA’s Hybrid bulbs provide high output and reliability that today’s drivers demand.
Engineered with newly-developed bulb coatings to provide drivers with a brighter and whiter beam than stock bulbs. Hybrid bulbs give more contrast and brighter down road illumination allowing drivers to see farther for greater safety and comfort.
9006 (HB4) Xtreme White Hybrid Twin Pack Halogen Bulbs installation instructions
The factory fog lights on my 07 Lexus ES350, didn't give much visual aid once selected on. The 9006 (HB4) Xtreme white Hybrid is an impressive upgrade! Now that near ground visual feedback has almost on "dark scatter" which most factory fog light systemes have. This Hybrid white color extends out to where the headlight pattern begins with minimal overlay too much headlight / fog light overlay is distracting. Not here! I highly recommend The Xtreme W. Hybrid.
I've been using PIAA bulbs and driving lights for more than 20 years. This bulb gives off a bright white light! I plan to buy these bulbs again for my other vehicle when the time comes.
Short of completely new aftermarket headlights, these bulbs are noticeably brighter, and thus safer, for our kids' beater car. Can't speak to longevity yet.
