Well as it says above I recently just bought a set of smoked led cab lights. I have no template so I'm trying to find the measurements/layout online. Just curious if anyone had any advice before I jumped into this?
No template??? Wow that would make the install interesting. When I installed mine they came with a template. I would try your local dodge dealer parts and see if they can give you the template that comes with the OEM Cab Lights. It was defiantly a big help for me when I installed mine. Hardest part for me was the first hole you have to drill, once I got the first one down the rest went pretty smooth.
Let me qualify this by saying that I have not done this mod but I found this link which might be helpful to you in laying it out. It is for a 3rd gen truck but the layout looks like it can be used on any truck. Cab Light Install
I may be mistaken, but i seem to remember someone typed that there were some markings under the head liner on the Generation 4 Rams.
I guess that if they are there, you will see them when you drop the headliner
