OK so I got a bug up my but since I have a light out on my trailer I want to upgrade to LEDs. First Ranger sure knows how to build a trailer. They welded steel tubes to run the wires through. The only thing I Don't like is the marker lights are pop riveted which mean I have to drill them out and replace with screws and nuts or buy some stainless poprivets. I do have a question. I've never dealt with those splice clips --- when you take the old ones off and put new ones on does it mess the main wire up and does it stay water sealed or is it best to change the whole thing main wire and all?
