My brother did a post on LED lights on his Horizon trailer for his side boxes. The problem he had was drilling holes We we got together last weekend and had a brain storming session on how can we do this and keep the lights protected and drill less holes here is what we came up with. His set up is a bit different than mine but you can get a clear idea what I did.
I wanted to use LED period and I need thin ones! After searching a bit Richard told me he some thin ones at Autozone. After a short trip I found what I needed. I closed the bin doors and they were a tad to thick damn it they almost fit. I got the idea to peal off the dow sticky tape on the back side and they slipped right in. Now how to get them to stay put? Silcone adhesive! When it dries it's pretty hard to peel stuff off. I know. I uesd some years ago to adhear tie down points in my Toyota as I did not want to drill holes, Let me tell you, try pulling them off , that was not going to happen, they were on there to stay, so why not for the lights There is no pulling on them and so lets give it a try. One word awesome! After I checked the placement, they were set in place to dry. So far so good. next was to hide the wires. I just ran the wires inside of the weather stripping being it was hollow all rubber and well protected. When I came to the end of my box I drilled a small hole set in a rubber gromit and ran the wires thru.
The wires for LED are very small/thin, It worked out perfect as the weather stripping had a slice in to make a 90 degree bend. I mounted the micro switch where the weather stripping came together drilled a hole sealed it and mounted the switch. I ran wires to the switch that was ran behind the drawers and held in place with stick on pads and wire ties out of site and protected. Tapped into the hot wire that was already fused and mounted a ground wire to my backup lights bolt done.
The small square lights in the stove area and the end stroage areas are held in place with the same silocone adhesive and are tied in together. Run 1/4 wire loom over the wire to make it look like you know what you were doing more stick pads with wire ties and your done. I did both sides the same way to keep everything uniformed. The square lights came in a package of 8. Some of the wires you see is just rough wires till I had my placement of lights and wires where I wanted them. Next project is to mount lights in my RTT. That was already done and will set up a post for that later. Enjoy. They put out plenty of light at night for cooking or looking for other items in the bins and drawers.
