An outstanding plug & play option for those who are sick of driving around with subpar weak halogen bulbs. The difference is literally night and day. Auxito craftsmanship is top notch on all their products but this bulb takes the cake for executing an all in one solution without the need to route and mount ballasts. Having the ballast, cooling system and bulb integrated into one compact design is the best iteration of the LED Headlight so far on the market. Instant on power, pure white light with actual lumen values/color temp. with no flicker, surges or canbus warnings. They are truly brilliant!!I was so impressed after install that I immediately purchased another set for one of our other vehicles. Don't waste time gambling with a random knockoff of this design to save a few bucks, the Auxito bulbs is EXACTLY what you want/need.
