Review on Enhance Your Vehicle's Interior with Nilight 60Leds 12V White LED Ceiling Lighting Kits - Perfect for Truck Van RV Boats Caravans Trailers Lorries Transit | 2 Years Warranty by Pete Brown

I have used them in a converted 12ft enclosed trailer. Each set is about 12 feet long so I lined up 2 rows and it's beautifully lit. I drew the lines with chalk and used the self-adhesive backing to stick the lanterns in place. I purchased #4 x 3/4" sheet metal screws (screws included) and added 1 screw to each group of 3 lights, attaching them even more securely to the wood on the ceiling, and connected them to 3 position switches so they can of can be turned on and off from any door Loading and unloading in the dark is no longer a problem I plan to buy more to install some low voltage lighting under our kitchen cabinets as they can be cut to any length without adding a string of lights waste.
