Dome Light Assembly – remove and replace.

1965 Chevrolet C10(half ton) – Model 1504 – Long Wheel Base Stepside Pickup.

The dome light in my 1965 Chevrolet C10 was not working one night. I popped the cover off to check the bulb and it had that tinted black blown bulb look. I went to pop it back in, to check it out the next day in the light and the snaps for the bulb went right through the back of the plastic housing. Must be faulty construction, it only lasted 46 years.

Then I went to rooting around the various vendors to find a replacement. I had read about the clear lens replacement from LMC Truck, and I was going to order one the next time I had some things to buy.

    A brief note : There were two versions of the dome light assembly. One has a plain white plastic housing, the other one looks the same except the base has the fake plastic chrome look. The originals both have a white plastic opaque lens. The chrome looking plastic was used on the fancier, Custom Cab equipped trucks. Those trucks also have the plastic chrome in other areas of the interior on various buttons and knobs on the dash. My truck is a plain base model truck with black plastic knobs and buttons, so I saw no reason to fancy it up with the chrome look.

I bought the dome light assembly with the plain white housing and also bought the new fancy clear lens. The dome light assembly from LMC Truck comes with the assembly, the long wire with the plug already attached. It had the white opaque cover and even came with a new light bulb! I was surprised at that, but felt it was a good buy after noticing all of that.

   Another note: My biggest aggravation with this project was getting the door sill plate loose as all of the Phillips heads stripped out on me. If your truck is beat up and rusty like mine, I would suggest working on getting that part loose before starting the rest of the project.

   To pull the wires through the cab. You leave the old wires in. You take the new wires and loop them together, taping each side with electrical tape. Then you tape it up real good and strong. I could not get the plug to pull through the cab. I’m sure there is some trick to making it work, but by the time I got to that point I was cold, wet, tired and mad. I cut the wires on the plug end about 6 inches from the plug. I then taped up the wires without the plug and it pulled through just fine. I then used some butt connecters and crimped ’em together good. Then I wrapped each one individually on each end of both connecters with electrical tape real good. I then wrapped them both together to get dirt and dust from getting in there.

I have light now and it works. Yay.

Follow along with the photos and the captions and you can get the idea of how you can replace yours if need be.


Before I did this job I asked around on some of the old Chevy truck forums. It never hurts to get another viewpoint about a project before starting it. You will always learn something you didn’t think about or find out a simpler and less aggravating way of doing things.

dome light assembly : how to remove and replace?

A project some folks like to do when they tackle the dome light replacement project, is to add a third brake light using a 1994-2009 GM Suburban 3rd Brake Light.

You can view photos and read about how lakeroadster did it on his truck, here.  The reason they do it at the same time is so they can pull all of the wires through at once. They also drill the hole through the cab to run the wires outside for the light.

The Pics:

This is the hole in the cab where the dome light assembly goes.
There are two flat head screws that hold it in place.
The reproduction part had plastic snaps to fit into the holes, so the screws were not needed.

Top of the fuel tank, behind the driver side of the cab. Shows the solid white and orange/white wires running down the two clips back there on the body. On my truck the wires ran down there, then under the door sill plate. From there it ran up past the dimmer switch to the fuse panel where the plug snaps in.

The door sill plate removed, you can see where the wires are routed.

the door sill plate on the gas tank / bed end, you can see the wires peeking out as they run under the plate.
