Burned Bulb Sockets on GMC Pickup

I know a guy at the office that had a 2000 Silverado (now has a 2004 Silverado) and has replaced the DRL lamps a few times. I'll check with him tomorrow and if no one else has a response here by then will post what he tells me.

Checked with a buddy of mine at the office that used to own a 2000 Silverado. He said that he changed the DRL bulbs twice (that he remembers) and had never noticed burned or charred looking sockets. He hasn't had to change the ones in his 2004 Silverado yet.

Then I checked with another buddy of mine that has a 2001 GMC Tahoe. He has changed his DRL bulbs once and also says he doesn't remember observing what you describe.

Curious, is this your 1st bulb change? I would think that if the bulbs were being over-driven by too high of voltage, they would have failed long ago. If you've changed them once before, maybe they were the wrong wattage (higher than design) and generating too much heat?

James, thanks for your input. I think I may have changed one or both bulbs in the past but can't remember for sure. Your idea about wrong bulb, wattage too high, is worth looking into. I'll check into this. Thanks again.

Just a thought. I know J.C. Whitney sells over-wattage headlamp bulbs, etc. and often cause overheating of the lamp assemblies for those people that use them (not to mention they're illegal anyway). Good luck!

I wonder if some were made with lamp holder sockets in a dark color instead if white. If they were already a dark color (brown or black) then the darkening wouldn't be as evident. Hmmm, curious question.
