Hi I have a 14 plate l200 with a tow bar fitted when new but it has just stopped working
All the other lights work
Would there be a fuse ? It seems most of the power comes from the rear lights as there is a 8 pin plug at the back that's not connected but two wires are hard wired if that makes Sense

what socket does it have

A standard uk 7 pin

is the a bypass relay fitted somewhere

No idea it's just dead and everything else works
