Wiring for spots.
Andy.:

Right main lights on dipped, fogs work OK, switch to main beam and they go off when the front spots come on. But when I flash using the stalk, pulling the stalk forward they remain on :?:
Before I could have them all on together :?:
Range Rover Blues:
Sound like the power for the fog light switch come from the dipped beam, when you pull the courtesy flash the dipped beam stays on (and the headlights get very hot). One fix for this is to use a diode from the main beam circuit to the fog light relay switch output (between the switch and the relay).
ChrisW:
As RRB said, when you hit main beam the feed to dipped beam drops out hence the switch feed to the fogs drops out and the lights go off!
Ideally you need to pick up a switch feed to the fogs from the side-light circuit so that when you switch side-lights on the fogs are 'enabled' failing that you could always use a permanent feed as the switch wire but this isn't the right way for fogs to be switched and I know what you're like (that and somebody will be along quoting construction and use regs!) :wink: :lol:

I thought as much Chris after reading the workshop manual I have.
Is there a side light feed off the steering column switch, I can't see any reference to one, so will it have to be from the engine bay, and will it be OK to feed off one side i.e the RHS side light feed :?:
Or how about using the rear fog light feed, but then I suppose when I turn on the front fogs the rear ones will also be switched on :?:

MMmm, I feel like coming up right now & having a look at this spaghetti, seeing as it's my last night of freedom :cry:
