JustGav Posted June 23, 2007 Share Posted June 23, 2007 Bizarre question... The yellow telltale light on the stock cluster underneath the odo for the light failure... Could I use that as a telltale for the foglight, technically it can be done, but would it be sufficient for an MOT as a telltale? Link to comment Share on other sites More sharing options...
Class One Posted June 23, 2007 Share Posted June 23, 2007 I have an illuminated switch on my dash with a red led inside. That seems to do. Link to comment Share on other sites More sharing options...

Going for a clean stock look on the dash, nothing stuck on or out of place...so want to use the existing telltales if I can... will look neater really Link to comment Share on other sites More sharing options...
TrickTT Posted June 23, 2007 Share Posted June 23, 2007 Anything that lights up will do, as long as its visible from the drivers seat. Link to comment Share on other sites More sharing options...
Matt Harwood Posted June 23, 2007 Share Posted June 23, 2007 Yes, it can be done, (I've done it on mine), but it's a bit tricky. I've used two relays in the boot triggered from the foglight 12v line. One to open circuit the bulb failure control units ignition line, and another to put a ground on the actual bulb output from the bulb failure unit. that way, when you turn the fog lights on and off, the bulb failure unit doesn't 'see' a fault because it's not on. When you turn the foglights back off, the failure unit cames back on and will report a buld failure if it occurs... Does that make sense? Link to comment Share on other sites More sharing options...
