Halogen lights?!

The standard lights on the 98 caravan are not halogen. Has anyone upgraded to the Cool Blue halogen lights by Sylvania? If so how are they any problems? Are they much better than the standard lights? How easy was the install?

Thank you in advance.

I just put Sylvania Silver Stars in my Olds and I love them, I wasn't into the blue ones these are nice and white.

The Sylvania Silver Star is a better choice. True white beam and brighter to boot. It may not have a long life but it certainly improves performance.
