Sylvania silverstars are a joke. Don't go with those "7000k" bulbs either. they wont last long and the color isn't what you'll expect. RAZO makes bulbs in the 4thgen size (9006 or HB4) that are really nice. they're called "Premium White Zeros." They're normally like $80 but i got a pair on ebay for $8 with shipping through dealtree. They're the brightest/bluest bulbs i've seen with stock wattage. If you want, you can get the PIAAs. they make a bulb called SPARK BLUE. Those are really nice, but expensive. But just dont get the generic ones. I went through, lightglow, eurodezigns, generic japanese import ones, none of them are that great. but the RAZOs...wow. Just remember to get ones that are stock wattage so you dont melt your harnesses. Go on ebay and search "RAZO hb4" and remember to get the BG606 color because BG607 is royal white, and you dont want that. Premium white zero is way better. Ok i'll stop talking now.
