The PIAA H11 Style Plasma 55=110 watt bulb provides 110 watts of light for 55 watts of power, and produces an amber/yellow light using patented ion crystal technology. Less reflective than white, this light reduces the amount of glare in extreme fog and improves visibility in inclement weather. It is designed with a high-quality heat-resistant tube.

Put these in our last and current Toyota 4Runner. Way better than the factory white bulbs. I can see deer approaching the road 30 feet beyond the road shoulder and they are great for seeing the edge of the road in a blinding snow storm.
Big difference from standard white fog lights. Awesome in the rain and snow.
