Thanks folks.
I understand that the 4,000K is the color temperature not the thermal temperature and the 6003 bulbs are rated at the same wattage as the stock bulbs, but I just wanted to make sure they weren't too hot for the application. The Siverstars are supposed to be brighter than Sylvania's prior high energy bulbs and that's what attracted them to me. I may hold off on the P5 as my wife says the stock lights are really very good and the best of any car we've ever had. She drove the car through the violent storms we had last Sunday (5 people died in them here) and said the headlights and fogs really did a good job. I did pick up a set of bulbs for the Civic today as Autozone had them for $19.95 apiece. I don't know when I'll get them in. I don't have a digital camera yet, so I have to get pics put on CD by Kodak. I'm too tight to blow the cost of a 12 exposure roll and processing for one or two pics. I'll post when I get the bulbs in the Civic though. By the way, the store rack had 9007 bulbs hanging there. Actually, they had 9003s, 4s, 5s, 6s, & 7s. Jim
