I think I need a trailer for my RT-S and I dont want to pay the price of a new one, so I'm looking at used. When I bought my Spyder the dealer talked about the LED lights ontheir trailers and didn't know if I could hook up lights from some other trailer. Is anybody pulling a trailer with car bulbs and did you have to do anything special ?????? I see that Can AM makes an adapter to 4 prong, but My dealer said he didn't know if it would hurt the electrical system ? Thanks Rick
