Yostumpy Posted December 7, 2006 Share Posted December 7, 2006 Evening all. My '98 300tdi ht is ex fleet user, when the ignitions on and I put the sidelights on the small upper lights, light up as they should, but also the headlights seem to have another sidelight in them that comes on about 1-2 seconds later, and when I turn off the ign. the h/lights ones go out and the small ones stay on. I only mention this 'cause I 've seen quite a few late model 51,52 reg driving along with just the small ones lit. MY question is has mine got a strange bit of fleet wiring, have I got a bad earth and its actually the h/lights glowing dimly (they work purfect on their own), or is it one of those things that LR put in , then take out, from model to model. I'm sure some body will Know the answer, bonus point for the first correct answer!!!!!!!!!!!!!!!!!!!!!! cheers stumpy!! Quote Link to comment Share on other sites More sharing options...
Andy Posted December 7, 2006 Share Posted December 7, 2006 thats the dim-dip system that was only fitted for a few years. they often fail as they get older so you cant turn the lights off.i think it gives the headlights 9v with sidelights & ignition on. i dont know where the control box is on a defender, but on a disco its an orange multi-plug behind the fusebox. just unplug it if you dont like it, then the lights work 'correctly'. p.s. can my bonus point be a brownie point? im saving for a girl guide Quote Link to comment Share on other sites More sharing options...
western Posted December 7, 2006 Share Posted December 7, 2006 That's the Dim Dip system, originally invented to prevent vehicles driving in built up areas on sidelights only, earlier vehicles have a black transformer behind the instrument pack, later vehicles use a relay in fuse box & resistor under the right front wing. on the transformer vesrion if it diidn't work full lighting could be restored [except dimdip] by unpluging the connector, not sure if that works on the later versions, IIRC it's not a MOT test item ---- I like to have mine working correctly.
