all there needs to be is a indicator light to say the rear fog light is on, so you carnt drive round with it on all the time. All that is needed is a light weather it be in the switch or on its own it just needs to come on when the fog light is on.

I just bought a switch from Halfords that had a light in it. Mine didn't have a fog light or fog light switch in it anyways, so I had to get a switch and wire in my bottom brake lights to that switch via a relay.

Also I think you have to label the fog switch up so that it's clear what it's for. That's what I read a few years back, not sure if its still true now.

Thanks for the reply (rep added), i've got a fog light switch on the car but nothing lights up inside when it's pressed.

You need a lamp to come on inside the car to tell you the rear foglamp is on.

Should be easy enough to fire an illuminated switch in (any motorfactors/halfords will stock them) just need a few extra wires to make sure the thing lights.

And yeah, it's a MOT fail if you don't have one.

IF it's one of those rocker switches with an LED built in, the switch probably isn't wired correctly.

I'm guessing you have the fog lamp earthed and the switch switching the +12v to the fog lamp? Do you have an earth connected to the switch to ground the LED?

If you take the switch out the terminals are usually labelled to show which connections are for the fog lamp and which ones are for the LED indicator.

There's just the stamdard push in fog light switch, there's got to be something that lights up somewhere as its passed mots in the uk before i owned it ?

I had a rocker switch before, lighted up fine etc, it passed but i did get an advisory saying that it should really indicate WHAT is on, so he advised me to write fog/rear fog on it ?!
