2020 Chevy/Sierra Roof Lamp Measurement

[Blackrebel88]

I am going to be adding the OEM 2020-21 Silverado/Sierra 2500HD Roof Lamps to my truck. I noticed a lot of the 2020 2500s do not have them, and I prefer to have them on my truck. I have all the proper parts and someone to install them. However, I cannot seem to locate the exact measurement for correct installation on my roof. Would anyone happen to have the exact measurements or be willing to measure there truck if the have the roof lamps already installed??

Hi.  New member here with a new 3500HD.   The center section is 5&7/8" to the front edge of the roof.  The single side lamps are 4&5/8" to the front edge and 1&3/4" to the edge of the roof on the inside of the plastic trim strip.  Hope that's clear.

There is a whole thread on this by Hotairgypsy.  He did a fantastic job paving the way for us on this subject.

Good Luck,  I added myself and love the way they look.
