Default Cab roof lights

I'm thinking about having some roof lights installed on my 2017 Sierra 1500. (Like on the HD) anyone do this? Which lights did you use? What is an estimate for installation? Doesn't look too hard but I'm not doing that myself on this expensive of a truck.

If you put the 5 on the front roof, I believe to be in compliance with DOT rules, you must have the 3 red in the middle rear, and markers on the side. One thing I do know for sure is, you don't want to be on the receiving end of ANY, DOT ticket.

If I were you, I would look further into this.

I haven't heard of this done in a long time, and even then it was someone doing it themselves. Best thing to do in my opinion would be to find the place you want to get it done and see how much they quote.

Agreed, definitely brush up on the laws when doing ANY light modifications.

One example of a clearance light regulation:
https://www.legis.iowa.gov/docs/code/321.392.pdf
5. Every motor truck or combination of motor truck and trailer having a length in excess of thirty feet or a width in excess of eighty inches shall be equipped with three identification lights on both front and rear. Each such group shall be evenly spaced not less than six nor more than twelve inches apart along a horizontal line near the top of the vehicle.
Make sure you know the laws on both the Federal, and State level.

Interesting, what do you mean 3 in the middle rear?

The trailer I tow periodically has those but my truck is of course stock.

The way I read this tells me that when I'm pulling my 22 foot car hauler I'm technically required to have the roof lights?

CathedralCub'* opinion: I agree that it'* a good idea to know the laws etc. At the same time, I've seen about a zillion half-ton vehicles with clearance markers added to the front of the cab and not the back. Suburban and Yukon 1500'* and C/K10/15'* and half-ton pickups from all of the big 3 etc. I personally believe these were all done for aesthetic purposes, and especially because they wouldn't, as a half-ton vehicle, be feasibly able to be legally carry enough weight to be required to have clearance lights. If they tow a trailer that, by dimensions and/or capacities, require clearance lighting, the trailer will need or have it installed.

The only exception I can think of . . . and find for that matter . . . is the early-2000'* GM Quadrasteer pickups and SUV'*. They were all 1500'* except for the Suburban and YukonXL versions which were only available as 2500s. For some reason they all had traditional clearance lights on the cab in front, three traditional clearance lights near center between the bumper and tailgate or on the roof forward of the third brake light on the Suburban/YukonXL, and clearance lights front and rear on the slightly-wide rear fenders. They even had an 8-lug 1500HD pickup version of this.

I just looked around for reference at 2018 models and Dodge, Chevrolet, and Ford all do not have rear clearance lights on their 3500/350 series pickups. Even the F450 doesn't.

As for the wording of https://www.legis.iowa.gov/docs/code/321.392.pdf , it would be important to know the definition of "motor truck" as it applies to this document. Very often, half-ton pickup trucks are considered cars for the purpose of many laws. Think like a 1973 Buick Estate Wagon with a 455 pulling your trailer. It wouldn't need clearance lights on the cab, but might on the trailer depending on the trailer dimensions etc.
