Hi thanks for the reply. This is exactly what I thought but I don’t know why as the left side works perfectly. Is there anything I can do ?? Also I’m not sure if it has dedicated wiring to be honest not much of an expert on this stuff but wouldn’t have thought so as the corsa has the towing capacity of a mobility scooter

Hi all, I’m wiring my towbar lights into my car.. on wiring the right indicator light, the trailer indicator works when the cars rear lamp is disconnected,as soon as I plug in the car light the indicator on trailer stops, any ideas ??
