I would steer clear of aftermarket cab lights. The Recons are junk. On my previous truck I added cab lights. IN order to keep with the black out theme I ordered Recons, and the quality is crap. I opted not to install them. I then ordered two other pairs of cab lights from Putco and some other brand (i forget). None of them were high enough quality for me to risk a leak from my roof. I kept the OEM cab lights I had the dealer install and added LED bulbs and never had an issue over 140k.
During the search for my current truck I found several that had every option I wanted except cab lights. I asked about having them added, but explained I wanted the 19+ OEM LED cab lights. I got some stupid prices like $1500-2k installed. I kept looking until I found a truck with cab lights from the factory.
If I were you I would look at adding the 4th gen OEM cab lights. They will be far superior in quality than anything aftermarket. They come with a template to ensure proper mounting location. And the rubber gasket is confidence inspiring compared to the crap included with Recon, Putco, and other aftermarket brands.
I believe I still have the Putco and other smoked cab lights...if you are feeling lucky send me a PM, you pay shipping and you are welcome to have them!
