How To ... Access & Change Daylight Running Bulb??

[Dave1]

I have a 2006 GMC 2500HD 4WD Duramax pickup truck that has a burned out daylight running light bulb. This is the small single bulb in what appears to be a twist lock bulb socket directly below the headlight assembly. I cannot get my hand down in there to get the socket out of the reflector where I can change the bulb so I assume something has to be removed to gain access to the small light bulb socket.

Can anyone provide info and directions what I have to do to get to and change that bulb?

Thanks, Dave

can you pull out the main headlight assembly then access it that way?

when looking directly down on the headlight, there is a long metal pin running alng the top holding the headlight in. remove the pin, and the headlight should swing out IIRC there is only one pin, then you can get to the daytime running light and just twist off the back and put a new bulb in, if you know what your doing it should take only 5 mins to do both sides so thats just showing you how easy it is.

When looking down at the top of the headlight assembly there are two vertical "L" shaped pins, one on each side of the headlight assembly. They appear to push down, then turn to one side, and lock into that position by a friction fit in a small rubber gromet for each of the two pins.

If I remove those pins, will the headlight assembly come out? If I get the headlight assembly out, it appears I can get to the burned out bulb sock for replacement. Will the headlight assembly go right back into the same exact position, replace the pins, etc. without effecting the headlight adjustment?

Is there an easier or better way to access the burned out bulb socket?

Thanks, Dave

yep pull both of those pins and then re install the same exact way, no it wont affect the headlight adjustment, and that the fastest way that i know of, unless you want to take the grille out which would be a pain in the ass. its a tight squeeze to get your hand down in there but its possible and the best way to do it.

OK, headlight assembly came out exactly as you described, then I could reach the burned out bulb twist lock socket. The twist lock came out OK, but the bulb would not pull out of the socket. I noticed two pin locks on the side of the bulb socket so using a tiny screwdriver, depressed one then the other of those pin locks while putting steady outward pressure on the bulb, and the bulb and a smaller socket came out together. It is actually a socket with bulb inside the larger twist lock socket.

The Sylvania bulb has a number of 4114K on it. I haven't been to the parts store yet but intend to replace both left and right sides. Is the bulb itself supposed to come out of the smaller socket or is the bulb and smaller socket a one piece assembly?

Thanks, Dave

i have an 03 2500hd and had to change the whole assembly from moisture. just turn the pin and pull the head light out, it might have to be turned a lil bit it comes right out. that should get ya right in there, the bulb snaps in the socket, the bulb it self has a little rectangle end thats plastic. id just replace the burnd one and save the other...

The headlight assembly comes right out, goes right back in easily. With the headlight assembly out, I can reach in and remove the DRL socket and bulb fairly easily. The bulb is a little tricky to get out as it is a socket within a socket type assembly.

Upon removal of the bulb/socket I noticed the socket is burnt from what appears to be excessive heat. I checked the passenger side bulb/socket that is still working OK and found it too was burnt. It is obvious these lights are getting really hot.

I searched the Internet for ""DRL Problems" and found some information that said there is some kind of electrical problem with the DRL's that causes the heat and bulb failure.

Anyone know anything about this? What is the problem and cure??

Is this a dealer warranty or recall issue?

Thanks, Dave

on my 99 silverado, the left one kept burning out. i just pulled them both and forgot about the stupid things. i always see the left side burnt out on chevies driving around. heat kills them.

i changed mine to amber bulbs ans what i normally do is turn the parking lights on then off and all the lights are off.

I dunno if it's a recall but it's a known problem. As YZ mentioned it's VERY common. I heard a radio car show host theorizing on it once and his belief was that it was because the power to them was routed through that light first and then on to the other side. This caused the heat and longevity issues with that side.

Yep, see it all the time and half the time the owners don't even know it.
