I thought it was a no-brainer to get a 6 month old headlight replaced that has a lifetime warranty after heavy condensation built up. I bought them as a set, their "DIY Solutions" brand, PART 1ALHP*******. After quite a wait-time on phone, the customer service rep informed me that wasn't covered under their lifetime warranty. These are for a 2007 Avalanche and are a MAJOR pain to replace. I couldn't believe they wouldn't stand by their obviously defected product. The service rep was abrupt, and had no intentions of even trying to fix the issue. I'll never buy from them again.
