Everything old is new again.
Thread's new to me, and I probably wouldn't have dug it up if it wasn't bumped back to the "front page".
FWIW. I changed to Silverstars about six months into owning my vehicle - went through about 2 pairs of Silverstars in the next couple of years - they seemed to burn out quicker than stock (which were OEM Sylvanias).
Finally just went back to ordinary 9007s - the Silverstars were brighter, but not really worth it, IMO.
Know someone running HIDs - they're really bright, but I don't need something that bright, and I don't need oncoming drivers constantly flashing their headlights at me.
Lot's of good info on lighting on "Daniel Stern Lighting" - Google it, it's full of interesting reading.
