Cab Lights
 

Hi, I have a question about cab roof lights for these trucks. How exactly do they mount to the roof? Also I would like some up close photos and some wiring help if anyone has some, I am wanting to put a set of original style cab lights on my 1985 GMC 2500. Thanks

One thing I did on my CC was to replace those pesky u clips with rivnuts. Also used some stainless allen bolts to hold them down.

Re: Cab Lights
 

Cool, I think I will do that to mine too. I hate those U clips lol

Hey Kevin, do you have any info on that installer?? Looks neat!!

Re: Cab Lights
 

I got the rivnuts and the tool both from Aircraft Spruce and Specialty. The tool was inexpensive. Not sufficient for a full time airplane shop but good enough for old truck guys. Rivnuts are a great "tool" to have in your toolbox. They're very handy if you want to make a ground connection to sheetmetal or install things like these cab lights.

Thanks TX Firefighter!!

Re: Cab Lights
 

As a long time aircraft mechanic. I can say that rivnuts are good and bad for some applications. I would get the ones that have a little dimple under the flange. It helps them from spinning when tightening or being loosened. You must drill a hole then take a small file and file a slot to except the dimple. You can also slide an internal lock washer under the head or even on the back side and squeeze against it sandwiching it between the rivnut and sheet metal. This will help it from spinning when taking it off in the future. You also have to be careful squeezing it. Being aluminum the threads can be pulled out easily. At least the ones from Spruce can. You can get steel ones but are harder to work with. Just some useless info for anyone who cares.

Thanks, Kevin. $20 ain't bad at all!!

Re: Cab Lights
 

And if you noticed I rewired my 2 outer lights to flash with the side marker lights which flash alternately with the front turn signals.

Great info: I used (for years) them in the transit industry, I can use this tip....:mm:

Re: Cab Lights
 

Thanks for the help everyone! I took the cab lights off our rotted out 1979 C60 down in the pasture and mocked them up on the truck. They look good. I belive they are the same as what they put on the pickup trucks. These are all cracked and busted up so they will be replaced with new ones. http://www.truckspring.com/heavy-dut.../VSM1313A.aspx

Only thing left for the looks of this truck is a simple black push bumper like the one pictured below and a 5th wheel tailgate.
