You know, I read the reviews below and they're quite comical. One guy leaves a vague generic review the same day another one leaves one for his Dodge product not working correctly. And a last complains that USPS didn't deliver in 2 days. Sounds like a case of mouth breathers to me. I've been buying sets from these guys for almost 10 years, ever since I found them on ClubRSX. Here's a breakdown of how my experience has gone, as well as proof. I ran a set of 55w H1 6k's on my RSX FOR 2 years, no issues. 55w 9007's on my 02 Impreza wagon, again no issues. The only issue I did encounter was that the wiring didn't work when I plugged it in, HOWEVER the owner went as far as to help me figure out why and it turned out it was the way Subaru's are wired. All I had to do was swap around 2 wires on the blue plug and it worked like a charm. Had these for about a year. Ran a 55w D2S kit on my S2000. Never had a single problem, and the upgrade over the standard and old 35w bulbs was absolutely incredible. Highly recommended! Ran a same kit as above on my 04 TL, as well as a 55w H11 3000k kit in my fogs. 35w 9004 kit on my '92 LS400, and this one did give me an issue. I ended up having a ballast fail, however after following the troubleshooting procedure they instructed me to do to verify it was in fact the ballast, they replaced it under warranty without hesitation. There are no gimmicks, there is no run around. Sometimes they do get busy, but I've never actually waited more than a business day for a reply and that's typically uncommon. My 2008 sti had 35w d2s 6000k bulbs, and 55w 3000k h10 I believe. Again, no failures. Currently have 35w d2s and a 55w 3000k h11 on my TL-S. I recently had 1 bulb fail, but that was my fault. One of my friends is going on year 7 on his H13 bi-xenon 55w kit on his 3000gt. No problems. I've gone through maybe 3 or 4 35w D2S bulb sets on various cars I've owned. The longest I've had a set was 3 years in my Mini Cooper for 65,000 miles, and are still going strong. No discoloration unlike the stock faded ones. Between my personal cars over the last 10 years, and all my friends/family that I've referred to Retro-Solutions there must be 40-50 kits sold and of those less than 5 total component problems. Anytime there was, the company never hesitated to honor their warranty. Take the other reviews with a grain of salt, more than likely I wouldn't be surprised if it's their competitors trying to smear their name. read more
