head light & day time running lights

[the blur]

my 03 Denali seems to burn up bulbs on the drivers side. it's the 9005 headlight, and the 4114K DRL.

only last a few months, and back to autozone....

 

the parts guy is trying to sell my dielectric grease, and I argue with him that is NOT causing the filiment to fail !!

Without knowing anything about the wiring layout of these trucks, I would investigate to see if the lights on each side run off the different fuses. Kind of a long shot, but I know on my wife's Miata it kept blowing the passenger side headlight. After the second one in a matter of a couple months I checked the fuse box and sure enough the fuse for the passenger's side was blackened, but the link was still together. My guess was that basically the fuse had created a short circuit and was allowing too much current to the filament. Replaced the fuse and all has been well since.

 

Now, I know that doesn't explain the DRL, but my guess given the job of the DRL is that it might share a wiring harness with the low beam.

 

Just my couple of pennies. Worth a shot right?

While I also mistrust parts guys, dielectric grease may well transfer more heat from the bulb to the socket increasing its life. If it is supposed to have this grease, I would use it. its awfully cheap.
