These lights are working great for me so far. I will reserve the right to change my opinion and update if needed. Based on all the bad reviews, I liked the lights and still wanted to have them on my truck. Because of the reviews, I chose to have them installed at a truck aftermarket specialty shop. I wanted to make sure the hookups were correct and the connections were as tight as they could be. Boy, am I glad I did. They had some of the same issues as everyone is posting...no directions for hookup and lights did not work when initially connected. But they worked through that and all lights work and look great. Now to wait and see how much longevity the H1 halogen bulbs have.UPDATE 28 December, 2015Just like everyone else, the low beam lights went out. Left side after 2 months and right side after 5 months. Real hard to replace the bulbs but bought SilverStar H1 halogen replacements and haven't had a problem since. Except when I hit a deer and the left light got smashed and the left headlight was still working. I have had no problems with the headlight intensity, except with the SilverStar bulbs, they are definitely brighter lights. I think if (or when) a high beam ever goes out, I will have to remove the whole assembly in order to replace because I am not sure I can get my hands down in there that far and also be able to see what I am doing.
