My passenger side low beam head lamp went out last winter. There are 3 bolts you need to remove to remove the lens, unscrew the lid, untwist the lamp and replace - while lying on the pavement in 15 degree F weather of New England. Lots of fun. (I wept like a little girl as I replaced this one.)

Last week, the drivers side went out, but at 85 degrees F, the weather was fine for this replacement. As I removed this lamp out of the "pigtail" receptacle, I noticed it had been slightly melted - a condition I should have taken more seriously , I suppose.

Anyway, I inserted a Sylvania H11Silverstar low-beam, 12.8V , 55W halogen (same as the one working fine on the passenger side.) Two of these lamps have now burned out - 1 lasted 3-4 days, the last one less than an hour.

So, if anyone has some ideas, that would be great. Thank you very much!
