First Day Review: I bought the 3 row, 60" strips a few weeks back and just installed them last night on my 2019 Ram 1500. I liked them so far. Here are some thoughts:- 4-pin Trailer Harness:Before installing anything, I wanted to test out the 4-pin harness connection. I opened the box that the LEDs came in and pugged them right into my 4-pin trailer hookup. All the signals and LEDs worked just fine with no issues.- Wiring:Simple install with a T connector into the original taillight connection.- Installing the LED Strip:The strip comes wrapped around itself, in a small-ish box. When I was ready to install them on the truck they kept trying to roll back up... this made it tough to do.Before installing I cleaned the bed thoroughly with soap/water, a degreaser, and made sure it was dry. Once clean I used took time to center the strip and placing a small piece of electrical tape onto the bed of the truck and the strip to know where the center point is in case it moved.I started on the side of the drive, peeling off a little tape. I applied a bead of rtv silicone adhesive to the bed and pushed the strip against the bed, holding it there for a minute or 2. I worked my way across the bed, ensuring it was lined up/even with the bottom of the tailgate where I thought it looked best.I had some issues with the beginning of the strip pulling up by the time I go to the end. And then I had issues with the end once I went back to the beginning. I ended up jamming a roll of electrical tape on both ends for an hour or so to ensure it stayed.- Overall:They are super bright. Awesome for more visibility to bad drivers around me. And being able to back up with more light is great. If someone in the car behind me is blinded, that sucks.
