i just replaced my stock headlight bulbs on my 98 z28 camaro with cool blue bulbs and wow what a diffrence it makes for the $35 bucks you spend on the pair. If you want new brighter bulbs i highly recommend getting them there one of the best if not the best bulb on the market atm.

 

Just my $0.02 from having done research on headlight bulbs, but since cool blues have the blue tint it traps in more heat making the lifespan of the bulb shorter. They're also intended for aesthetics mainly, and the Silverstars and Silverstar Ultrasare suppose to be brighter with the HID look.

 

ehh i hate blue lights...
i want something white... but sorta cool... just not the plain old yellowish halogen
are silverstars good for that
i hear theyre good
but if theyre blue **** em

 

Silverstars are good bulbs. You can get find them for like $45 for a twin pack. I've got the Xtravisions on mine now, kinda like the Silverstars but cheaper without thewhite look.

 

Cool Blue = worse than stock in my opinion
Silverstar Xtra = a little better than stock
HID FTMFW

 

i acutally took one headlight bulb out and replaced it with a cool blue bulb and the diffrence was pretty big compaired to stock and acutally tell you the truth the lightisnt blueits clear light not like some halogens that have a yellowish light. I acutally went out on the road right after and even with my lenses semi fogged its a step down from having your brights on.
