Hi to everyone, this is puzzling me ??? I have a Disco 4 66 plate, with led lights,  the disco did not have wiring fitted for a towbar so I bought a wiring kit for my disco from PF Jones which was easy to fit. 

I've noticed though that my led side lights on the caravan which is a swift challenger 2011 do not come on. All the other lights on the caravan work, indicators etc as these are all non led.

That is my question is it the wiring kit on do I need a VLM unit. My friend used there 2020 mitubushi jeep to connect to my caravan and all the lights worked even the side lights.
