The night before last I discovered that my right headlamp had burned out. So as you've probably guessed I replaced it along with the left one. When I went to the store I found that they had the new Sylvania Cool Blue lamps available to fit the DeLorean. After using these, I'll never even consider a headlight conversion again! The bulbs are ALOT brighter then the stock lamps, and are much more white. The complete specs for the bulbs are on Sylvania's web page: http://www.sylvania.com/prodinfo/auto/cool/welcome.htm Low beams: H4656 CB High Beams: H4651 CB Rather then use the long H codes Sylvania put's on the box, you can just go by the simple codes on the bulbs themselves: 2A1 for the low/beams, and 1A1 for the high beams. The odd part though is that the bulbs themselves will say SLYVANIA on them, but the package for the sealed-beam version says GE on the box. Either way, they're the same lights. -Robert vin 6585
