yeah, there are lots of cheap crappy colored bulbs out there that can cause bad things to happen, but these are not that kind of bulb. eurolite has been around for a while. i had a single pair for my low beams running 24/7 for over two years and they never failed to perform. i have used autic lights which were really neat, they were rainbow blue, which looked like blue with hints of yellow, but in actually night driving, it was like driving with cheap night vision because they looked greenish from driver position. silverstars were better than stock, but pretty much looked stock. not really as showy as i wanted and went out in just a few weeks. but the eurolites were great, bright usable light with a nice crisp blue color to them.

and if your worried about them melting your harnesses, get one of those pig tail harnesses for safety sake.

 

You do know you don't have to buy a new kit, right? You can just buy replacement bulbs in whatever temp you want using your existing ballasts.
