At first, theses were great as they were a significant increase in light quality over my stock halogens. My car is small and removal, and replacement, of headlights is not the easiest, but the light and plug do fit fully in the headlight housing. No issues with glare for on-coming traffic.Less than 10 months into having these lights installed, there is significant buzzing noise coming from the fan at the base of the lights. Easily heard from inside the car. I checked to make sure the light didn't come loose in the housing and everything looked fine. Tapping on the fan housing at the base of the lights with my finger caused the sound to change, mostly got louder, but they will not go quiet.Only positive at the moment is the lights still seem just as bright as when I bought them, and with the stereo loud enough, I can't hear the horrible buzzing. And, this is the only reason I am not giving them a one star.I would recommend passing these by and look for something better.
