We have a Geist Caravan the lights are not working at the rear of caravan the front and side lights are working we have replaced the bulbs but still won't work .Has anyone else had the same problem or can anyone help please
As Usher says above, check that you have voltage coming to the rear lights that aren't working, once we know if there's any voltage getting to the fittings then we'll be able to help more.
As discussed you need to measure the voltage going to the rear lights. Start at the socket where you plug the van in. If you get voltage there you need to work your way towards the back along the electrical piece of string to see where it stops. Somewhere by the sounds of it, there is a break in the "string".
Had the same problem with my Geist,,,take one of the back light covers off ..see if the connecting wires are live...if not its probably the connector which is only accessible by taking of the bottom back panel ..i was lucky that i wiggled the wires until i got power then taped them securely into place
