Review on Partsam Submersible Utility Trailer Identification by Matthew Goozmer

I have 3 of these installed on each side of my Peterbilt bunk. I connected the light wire to the hot wire and the ground wire to the bolt that holds the light bar in place. It worked fine. It replaced the five 6 1/2 inch lights that were there. Much more light. I've just ordered two more sets of 2 to fit under the driver and passenger doors to replace the three 6 1/2" lights that are there. I had to drill new holes to install them and a big hole in the middle for the wires to go through. The trouble was worth it. UPDATE 6/9/20: I added 2 more sets (10 bulbs) under the cab doors shortly after I wrote the first review. I downgraded my rating to 4 stars because the 2 lightbulbs on the sleeper no longer work. I tried switching the wires from light to normal, checked the ground but they are missing. They went through a phase where they sometimes worked and sometimes didn't. Not at all now. 4 stars because only 80% work.
