I know they only have a life span of 1 year, but if you add some dielectric grease to the connection it really helps the life of the bulbs. I have had my sylvania silverstar ultra's in the fogs for almost 2 years now

 

my head light bulb went away the job seems to be pain in the *** so till im in there i will swap head light and fog light and yellow corners so 9005 for the fogs lights and what are numbers for side and head lights....what brand should i go with? i want the most powerful

 

most powerful, hella 100w bulbs (standard 9005's are 65w)

You can get em here for cheap...
