Hiya folks, looking for some help regarding the lights on my caravan.

When it's hooked up, everything works, indicators, brake lights etc etc.

Except when I turn the car lights on, if i have the car lights on, and then use the indicators, every light on the caravan starts flashing.

Any ideas to what it could be???? Someone suggested an earthing problem to me, but I don't have a clu about these things.

Definatly sounds like a bad earth.

if not the socket end possibly full of water. then the lights themselves

try removing the light lense and cleaning all contacts.

have they every worked correctly??

check all plug terminals 12N  first,if earth is ok could be a water ingress problem ie.water entering the lights  at the rear.
