so where do you guys suggest buying these?

 

Most stores that sell Sylvania headlamps should carry these or be able to get them.
I don't think you need to upgrade your wiring since they are the same wattage as the stock lights, they are just brighter and whiter.

 

Saw em at autozone last week when I went to replace one of my bulbs. I'd have bought one but then one bulb would be brighter than the other. I was feeling too cheap to go ahead and replace both my working bulb and bad bulb with the Silverstars for a complete upgrade. Looking back, I think I would have done it. Why don't both my headlight bulbs ever quit working at the same time?

 

When one of mine went out, I changed both. Went with the Sylvania Cool Blue. Nice upgrade from what I had.
Mine don't have many miles on them, anyone wanna buy my Cool Blues?
