Bests & Worsts Reviews from Amazon

I replaced my high beam bulbs with the Ultras a few days ago. Much better light pattern now, can see the signs at night much better. The light is much whiter with a blue tint. Would recommend to everyone that drives at night. Some other reviews say that the Sylvania bulbs burn out too soon. Being a technician mechanic most of my life, the main thing you must do when handling these bulbs for install is wear gloves. The oil from your hands will create "hot spots" on the bulbs and they will burn out prematurely. So buy some latex gloves and put them on from the second you open the package, to when you are done. Then they will last longer than a year. My 9004 Silver Stars in my Jetta are going on three years now.
