tomssupra Posted November 30, 2006 Share Posted November 30, 2006 Hi All, Whats the quickest way to get a fog light on for MOT purposes? I have a switch on the dash but it doesnt do anything - I just want to wire some cheapy kit up for the test... Thanks, Tom Link to comment Share on other sites More sharing options...
Nic Posted November 30, 2006 Share Posted November 30, 2006 How about doing the fog light conversion, see details here: http://mkivsupra.net/vbb/showthread.php?t=80479 Link to comment Share on other sites More sharing options...

Thanks, Tom "Quickest" way I reckon (assuming you dont have failed buld indicators) is to: 1) Chop the two wires to your driver side reversing light, you now have two cables going to the bulb holder and two going back into the harness. Tape up the two harness wires and tuck them out of harms way. 2) Connect one of the cables from the old reversing light bulb holder to the LIVE side of the rear tail light. I used a scotchblock connector. If you like I can look at mine at the weekend and tell you what colour it is. 3) Run a cable between the remaining cable on the old reversing light bulb holder and the dash area. 4) At the dash end connect this cable to one side of your switch and the other side of your switch to a good earth point. 5) Fit nice bright red bulb into the driver side reverse light. When the lights switched on, the new bullb will have a 12V feed from the rear light feed (which is fused anyhow). When you close the switch on your dash it then completes the circuit and the red bulb comes on. I was a bit worried that this would not pass the MOT, but on Tuesday it did and with no comment at all from the tester. Only thing is, you have to (they claim) have a light or indicator in the car to tell you the fog light is switched on. The switch I used had a built in LED and I took a feed for the LED side of the switch from the dash light supply. But there are loads of other ways around this I am sure. Good luck if you try this method. If you have failed buld indicator you will either have to put up with the fact it will tell you that a bulb has failed or measure the impedence of the original bulb and connect a resistor accross the original feed to the reversing light.

tomssupra Posted December 2, 2006 Author Share Posted December 2, 2006 Shane, Cheers for that, I think that was what the did before I bought it, but it had stopped working and I didnt know what they'd done - but I do now...! Thanks, Tom Link to comment Share on other sites More sharing options...
