Silverstars run in the neighborhood of 30 bucks a set depending on where you get them, and they actually do improve lighting.
The best thing you could do for the money would be to buy two sets of 9005 Silverstars, run one set for your high beams, remove the tabs from the other set and run them as your low beams.
I sometimes like the looks of the blue-lights as well, but I do a lot of driving on the outer edge of nowhere with little to no ambient light, so I want functionality, not looks. But if you drive a lot in cities or whatever, then why not.
Thats not a bad deal for 40 bucks and you get all 3 pairs, but I dont agree with their claim that they are brighter. Sylvania makes it clear that their KoolBlue lights are not brighter, so I find it hard to believe that "Eurodezigns" can improve upon that.
They claim of 2 times brighter than stock is outrageous as well, my stock lights were bright, 2 times that would be close to approaching the glory of God himself.
Again, Im not trying to dog you either, Im just saying dont believe everything you read.
