For the past few years, every time I used my trailer there would be a light out somewhere. Finally I got tired of it when I noticed wires that were so stiff that they would crack and break apart if you bent them. So I ripped out all the wiring and installed a new LED kit from Harbor Freight. They look like very nice lights for not much $$, so its low risk if they don't work out. Anyway, for the first time I have 100% working lights.
