Most of the kits out there do seem to be overly bright and harsh which is why I have bought kits from this eBay seller over the years, I have them in my E90 and I have zero regrets. 1.5 years and counting, no issues at all. Just nice pure white light that doesn't blind you the moment you get in the car. Super cheap and fast shipping from a US seller, too.
