I took it for a test drive and living around Seattle, WA it was raining hard. The conditions were perfect since 3000K is a true yellow color so it helps illuminate the road better then other color ranges in wet or foggy conditions. At first, I was a little disappointed that they weren't brighter but then realized that this ballast kit aren't as quick to warm up vs. my the Slim Ballast kit. I would say they take 30-45 seconds vs the 5-10 seconds for my headlamps. The color starts off as a warm white color and then gradually turns to a true rally car like yellow. Once they are fully warmed up they work perfectly with the headlamps. The 4500k kit in the headlight is great at distance while the 3000k in the fog really brings out the road 20-30 feet from the front of the car.
In summary, I'm really happy with the overall setup. If you live in a wet or foggy area I would highly recommend this setup. I hope to have pictures up in the next week. If you have any questions feel free to post a comment below.
