A question re LED trailer lights, I have s 14 plate Occy  with hitch , professionaly fitted  with trailer options programmed.

The LED board worked on my old MK2, but doesn't on the MK3, the lights work, but seems to be a fault as the brake light alternate with indicators, and other malfunctions.

Would it be because of the cam bus for the lighting circuit? 

The old style board works ok, 

I had the plug of the faulty board and there's no short or loose wires,and apart from trying to get the LED units off doesn't seem at fault.

Did you have dedicated electrics (back to fusebox) or standard electrics (connect to cables in boot).

That I don't know, but I asked them to enable the tow bar programme, the info screen lights up when hitched, so presumably it's dedicated.

had LEDs on two of three trailers I've rented recently, worked without issue. Dealer-fitted towbar.
