Just wonder if anyone has any ideas what can be the problem with our car trailer lights. We know the fault if with the motor home as when the trailer is hitched to another vehicle the lights work perfectally - as soon we plug it into the motor home we just get a single red light on the trailer and nothing else! We have checked the wiring in the actual plug on the motor home and have tried to check the fuses but cant find anything obvious that has gone. We have a Fiat Bessacarr 2007 - help please! Thank you Funsters
