Around here, I am surprised when I see a trailer with working lights. I borrowed a trailer from a guy and when I hooked it up the lights did not work. He did not know they did not work because he had no wiring on his truck to plug them into. I passed a guy I work with one morning at 5:30 on the interstate with no lights on his trailer. I told him about it when he got to work and his response was ***8220;I know, that is why I did not go thru town cause I might get a ticket***8221;. Oh, but it is ok to kill some innocent driver on the interstate who cannot see your black trailer in the dark. Idiots!
