<< You shouldn't need to take the car to the dealer. There might be instructions in the owners manual.
Not advice for the original poster, but for everyone else: Just get something legal and not tinted, like the aforementioned Sylvania Xtra-Vision. GE, Wagner, and others sell similar ?high performance,? normal wattage, legal, white bulbs that will make a difference without the poseur (pull-me-over) look or the danger of melting the housings or wire harnesses. They?re only a few dollars extra per bulb, and they?re often packaged in pairs, for as little as $15/pr. (look at Wally-world), which completely offsets the extra cost of buying them individually.
Save your money and try those first. Any difference they make will be an improvement, and not just a ?difference.? >>
I had a pair of CoolBlue on my car. I bought it to see what the hype was all about and I needed a pair of spares to keep in my glovebox anyway. Coolblue is made to be street legal and it doesn't look whole alot different. It looks SLIGHTLY whiter, maybe by 200 Kelvin. The whole point is anything that makes extravagant difference won't be street legal. I put on my regular bulb and I have those coolblues in my glovebox as a spare.
