Well some Silverstar unfortunately lasted a few months which still can be under warranty. Sylvania claims they will last about 50-75% so about (1000-1500 hours) a normal life of a halogen bulb. So 2-3 years depending on how often you use them. If somebody knows the exact time and life please post it. I do know it will never be the same life as a normal halogen.

You can order online for about $45 a pair with a $10 mail in rebate so it ends up to be $35 a pair.:thumbup: www.suvlights.com

Or the auto stores sell them for about $45-50 with a $10 mail in rebate.
