BMW X5 reversing lights and rear fog lights go out when 12N & 12S plugs are pushed in

by J Preston

Everything works fine on the X5 but when the two caravan leads are inserted the fog and reversing lights go out on the car but are on at the rear of the caravan. When the caravan leads are detached the reversing lights and rear fog lights on the car still stay off.

These lights will only come back on after everything is turned off on the car and left for a short period before turning back on and then everything works fine again.
