HFolb23 I have cab lights on my truck. They’re aftermarket, so is my sunroof. One cab light leaked, the water took out the controls for the sunroof and it got stuck open. Dealership gave a lifetime warranty on it, and had it fixed the next day.

Even having aftermarket lights that failed, I’d still have them again.

Personally, I’m much more concerned about my leaking 3rd Brake Light because that came factory and hasn’t been touched since.

cjgoode My 2015 2500 megacab has them, just ordered that way. I love them, just the look I like. No problems with them leaking. I wonder if the people who have issues had them dealer installed as opposed to factory ordered.

Roof top clearence lights

I have them on my 15 DRW since they have to come factory. As a builder/roofer i hate unnecessary/extra holes in a roof. Even if installed right they will eventually leak. I have three of mine leak already and had them replaced. The platform the screw goes into is unsupported so just barely finger tight is about all they can take before cracking the housing. Mine came cracked from the factory installation.
My plan is to have them removed and the holes filled and the roof repainted. It is on my short list as my warranty is about to expire. Or it may be done after we get some Texas hail.
Also, there was an updated cab light gasket. So the lights that were leaking had to be returned by the dealer for the new seal type. When the second set came one was still wrong but they installed it anyway. This is aggravating because now i have two gasket types on my roof. For this updated thicker/softer gasket to look balanced i moved them to the outer position. This gasket also cups over the sides some. This makes a pool for the water so sit in. Thats the second issue with the screw that goes into the top. It is recessed with a cheap hard plastic washer. This creates a pool where water sits and percolates through past the gasket and into the light. It makes itself known as it starts to fog up. I inspect mine every week for now to make sure they are dry so my headliner stays nice. The older two lights are much more damaged by UV. The leak was discovered a couple of weeks after purchasing the truck new. At this time the lights were swapped. The newer lights have held up to UV and still look new.
All my lights are now siliconed in and the screws with their recessed hole is filled. The silicone is also around the perimeter of my third brake light.
I have no idea why someone would decide to willingly add these things.
When i do paint the roof i want to find a way to seal five LED bulbs to the windshield inside the cab near the headliner so i have the required lights without the necessary holes in the roof.

The thicker gasket traps more water and is the supposed new part. The photos are two of the three replacements. In the image with the older flatter gasket you can see the original light that is significantly more UV damaged. It is a bit hard to tell but the older style gasket is pretty flat without the water trapping lip.

My truck has the snow plow prep package and shows the clearance lights as an added option on the sticker. The only things I know that the package comes with are the heavier alternator, skid plate package, and heavier front suspension. My truck sits like it has a small leveling kit on it from the factory.

cumminsdieselfreak I had them thrown in as part of the deal on my 2018. Out of pocket my dealer charges $300 for labor and kit.

Cummins0867 I like them and always have...they're fairly easy to install. I have installed them on about every truck that I have had that didn't come with them from the factory. The OEM kit comes with a template to let you know exactly where to install. If you follow the instructions you won't have any trouble with leaking if you use the correct drill size and don't over tighten the screws on the light covers. If you have a 2500/3500 the wiring plugs in right in the cab. I have also installed them on a 1500 and I ran the wiring out under the hood. I have also installed the Ram OEM light bar that mounts right under the tailgate but above the rear license plate. These are usually only installed on dually trucks but I currently have one installed on my 2019 Ram 3500 SRW, To each their own but I have always really liked the clearance lights on trucks.

Jaybo518 Not having them was one of my needs when I was looking for my used 2500! As it has been said, extra holes on roof to leak.

Phillipjon I am just the opposite, I did not want them. They all seem to leak someday.

Cummins_Michael When I was truck shopping, having cab lights already installed from the factory was a requirement for me....

WhiskeyThrottle i always looked at them as 15 unneeded holes in your roof... and somehow I always ended up with them.
