Review on Glowteck H13/9008 LED Headlight Bulbs Conversion Kit - CREE XHP50 Chip, 12000 Lumen/Pair, 6K Cool White, 6500K Brightness for Enhanced Visibility by David Banks

The stock headlights on my GMC Envoy 06 are pretty terrible and I've wanted to replace them for years. I tried some of the cheaper ones first and they ended up on ebay in about a week. I then switched to a more expensive brand and they kept flickering, even with their "customer service technology". In the end they were returned. Last try I went with the glowteck kit. I can't believe how happy I am with them! Pros: The instruction manual is actually GOOD ENGLISH! I know it's crazy right? The installation is the same as any other LED kit, no crazy work. Installation took about half an hour, which I find pretty impressive. The lights worked with no issues when I first turned them on. not overwhelming. I don't feel like I'm blinding people going in the opposite direction. High and low beam work very well, no contrast in quality. The 2 year guarantee is amazing. Assembly of the rear cover. I just made a small hole in mine and so far so good!
