liseanddavid Posted August 12, 2009 Share Posted August 12, 2009 Hello again! I have just replaced a headlamp bulb on the passenger side of my defender. However, when doing it I noticed an extra socket complete with wiring that appears disconnected - the socket is of the same smaller type as the side lights and indicators, the wiring is orange and black. All my side lights/indicators working, does anyone know what its for? Thanks again for any help.... Quote Link to comment Share on other sites More sharing options...
western Posted August 12, 2009 Share Posted August 12, 2009 there's a Red/Orange trace wire for the Left front side light & left rear tail light, also feeds the trailer left front marker/left tail light. Can't see any Orange/Black wires on the 300tdi wiring diagrams for lighting I have. Quote Link to comment Share on other sites More sharing options...
liseanddavid Posted August 12, 2009 Author Share Posted August 12, 2009 Here it is, as I say all my indicators work, it does not look like a rabbit run, I just wonder if I've pulled if of some where...it is orange and black.... Quote Link to comment Share on other sites More sharing options...

Nah, that's faded red and black, for sidelights. Turn the sides on in the cab and put a meter across it - bet you a pound to forum funds I'm right Quote Link to comment Share on other sites More sharing options...

A function of living next to a Land Rover owner - don't worry, they'll get curious / need a favour at soem point. I think it might be a spare pick-up point for something? At the risk of the neighbours calling the nice men in the clean white coats, is there one on the other side too? might be for additional sidelights?

No, nothing on the other side, it must be for something like that, would just be nice to know what it was. Quote Link to comment Share on other sites More sharing options...

liseanddavid Posted August 13, 2009 Author Share Posted August 13, 2009 Drove into work this morning and have discovered that the fuse for the headlamp has blown on this side again, full beam still works. From my original post, I've just changed the bulb and fuse, thats when I found this socket. I'm not sure that the socket is related?? The socket on the headlamp looks fine and is not the same.....as I said the spare socket is the same for the sidelamps and indicators.....

TheHarv Posted August 13, 2009 Share Posted August 13, 2009 ... don't know if it helps but the military ones have blue orange (colour code UO) there (with the usual black ground) for the 'blackout' lamps... Quote Link to comment Share on other sites More sharing options...

liseanddavid Posted August 13, 2009 Author Share Posted August 13, 2009 The orange/black and black wire with socket remain disconnected - the side lights, indicators and wing indicators all work, I'm sorry but the wire is orange/black and black.

western Posted August 13, 2009 Share Posted August 13, 2009 no need to be sorry , I Don't know what is for then, but as it comes from the side & tail light circuit, it's got to be something to do with lighting, what year is your vehicle? & I'll have another look over the 300Tdi wiring diagrams I have Quote Link to comment Share on other sites More sharing options...
liseanddavid Posted August 13, 2009 Author Share Posted August 13, 2009 Ralph, Have given up for the day, its year is 1998, 300tdi csw on an R plate, i'm sure its not anything to do with the headlamp problem I now have, must be unused. The fuse that is blowing is a 7.5 amp supply fuse. I notice the headlamp glows dimly after the fuse blows - is this an indication of an earth? If you have a cct diagram that would be great. Thinking it must be a relay. All I have is the diagram behind the fuse box. Thanks again for your help. Quote Link to comment Share on other sites More sharing options...

TheHarv Posted August 13, 2009 Share Posted August 13, 2009 fwiw I did happen to notice there's an 'OB' (orange w/ black trace) showing from 'alarm sounder relay' to 'alarm sounder' on both 96 and 02 circuit diagrams as you say it sounds like it is unrelated to your headlamp issue Quote Link to comment Share on other sites More sharing options...

Roverdrive Posted November 9, 2020 Share Posted November 9, 2020 I’ll have to check tomorrow, but I think it is for an alarm sounder which is normally mounted behind the headlight. Quote Link to comment Share on other sites More sharing options...
