JimAttrill Posted December 9, 2011 Share Posted December 9, 2011 Trying to get LED stop/tail lights to work on the '95 110. No go at all until I discovered that the lights are wired up 'backwards' ie. outer of bulb is + and centre is -. With ordinary bulbs this doesn't matter but the LED's (being diodes, after all) only work one way round. I checked other Defenders at work and this seems to be 'normal' but wrong, after all. So if you try LED's and they don't work, now you know Quote Link to comment Share on other sites More sharing options...
mmgemini Posted December 9, 2011 Share Posted December 9, 2011 Just like I explained to you FOUR years ago. Quote Link to comment Share on other sites More sharing options...
GBMUD Posted December 9, 2011 Share Posted December 9, 2011 Stop/Tail must be the right way round though? Chris Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted December 9, 2011 Author Share Posted December 9, 2011 The stop/tail is done by the two centre contacts, and yes those are the right way round except that they are both negative and should be positive. All this is not really a problem except that it is a bit of a pain to rewire the sockets. In fact, to tell the truth I didn't do this. Got my money back on the LED's and use ordinary old bulbs as before. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted December 9, 2011 Share Posted December 9, 2011 Chris. I had one front parking light on mine wired wrongly. Took me all of an afternoon to find the problem. The later LED's are not polarity concenous {SP} If the stop tails were wired wrongly. How did they work ?. Quote Link to comment Share on other sites More sharing options...

So, the shroud is live and when the lights are turned on the rear lights get an earth and when you brake it earths the brake light contact? Must be a SA special edition! How do you wire trailer lamps??? concenous {SP} Sensitive. Chris Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted December 11, 2011 Share Posted December 11, 2011 You sure your voltmeter isn't wired backwards? Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted December 11, 2011 Author Share Posted December 11, 2011 No, voltmeter is correct and this seems to be a problem with all the Defenders I have tested. Possibly all Tdi's. Trailer lights work fine. The front side lights and all indicators are wired correctly. It is just the stop/tail lights that are back to front. By the way, we have had a few cases where people have forced single-filament bulbs into the stop/tail light holders. This gives strange effects when the brakes are applied. With one old V8 Defender the front side lights would come on and we had a Defender TD5 where the engine would not stop if the brakes were on. This owner insisted his bulbs had not been changed etc. Maybe the fairies put the single-filament bulb in there Quote Link to comment Share on other sites More sharing options...
