Easy to install, the lights are bright and look really cool.Great tail lights. Fog over occasionally but usually clear up within a day.It looks amazing and was simple to install. My only complaint on these are the rubber gaskets that line the outside. They kept comming off and they weren't sticking to the housing much at all so I hope they don't cause a problem in the future.They look awesome for sure. The only reason they are not 5 is because, the seals are absolutely garbage mine were falling off when i unboxed them. So water WILL LEAK IN THEM, lucky mine didnt get bad, but you might want to fix the seals right away.Had to glue the rubber seal onto the tail light. When received the 3m taping wasn't sticking. The tail lights looks great. Would recommend to othersLove the lights, nice and bright but the tape being used for the rubber weather stripping needs to be strongerI received my tail lights today, and they arrived faster than expected. The description says professional installation but it hooks right up to wiring harness. Took less than ten minutes to install. They are an improvement from the oem tail lights, but the design makes them look freakishly small when installed. All in all, I'm still pleased with the productInstalled them on my 2007 Pontiac Grand Prix, they look good, and leds are nice and bright. Will see over the course of this year how they hold up.
