Cab lights

Has anyone ordered a new HD recently and been told cab lights are unavailable?

PJT69Z · January 6, 2022

Yes. I have a 3500HD LTZ on order and was told the cab lights were not available.

Same here. It's been off the list for a couple of months now.

Yep on constraint with no known ETA for availability yet.

Are you talking about the marker lights on top of the cab? I thought they were required by the DOT because of the overall vehicle width.

Yes, and no.

If it was a requirement the OEMs would be required to install them as standard equipment.

Here's a somewhat decent written article aimed at pick up trucks:

If you still have questions, your local State Trooper/Highway Patrol office can explain further.

Hope this helps, as it's pretty murky and could use an update to the CFR now that our trucks have grown as wide as our office chair asses.

Won't the drw's be required to have these? Maybe that is what constraint means in newdude's post.

Constraint means the factory won’t accept the order with that configuration.

Good question. I can't remember a dually without marker lamps.

Just for fun I went to the build page, and selected the dually option. As soon as I did, it added Cab marker lamps, and gave the warning about availability issues. Would need a dealer to advise if the truck could be ordered.

Just for fun I built the same truck as what my order is, except as a long bed dually. What a sexy beast! :thumbs:

Has anyone had any luck with aftermarket cab lights? Any successful installations?

Another JR · January 12, 2022

There was a thread about a year ago where someone showed their installation project. Probably in this subforum.

I just texted my sales lady and said I heard scuttle about cab lights are out now - I said, don't hold mine up over what's basically decorations. She replied, "I would've called you or had them taken out to keep it going" ... and I said that's what I want to hear, leadership that can make decisions! She knows me and she knows what my deal breakers are, certainly isn't roof lights. But she has a lot of distrust and dealers all think they are just being lied to because GM can't deliver anything and staging lots are sitting full of half put together bag of jellybeans.
