PIAA Xtreme White Plus headlight installation.
I just got these bulbs for my new cavy.
Claim: Extreme cool blue light, 4000Kelvins, like a 120/110W bulb.
Cost: $90 or so, depending on application.
Install: Easy.
Results: minimal difference, almost not even noticible. However, my cavy uses a 9007 light bulb, there may be a more drastic difference with an H4 or something.
