That'll almost definitely be an earthing issue on the trailer. Likely corrosion or a poor contact
It's worth checking the socket on the defender for dirt/corrosion but the fact it doesn't work on the L200 would suggest trailer fault to me. 2002 90 Td5 Station Wagon 1990 Vogue SE Triumph Tiger Explorer 1200 Td5 90 Thread http://www.defender2.net/forum/topic50767.html Tdi 110 Thread https://www.defender2.net/forum/topic69562.html RRC Thread http://www.defender2.net/forum/topic54492.html Instagram http://www.instagram.com/george_grafton |

Get yourself a tow electrics tester. I got mine from eBay relatively cheap. It tests the vehicle socket, and can be plugged into the trailer and test them.

It amazes me how poor trailer lights are. Most probably a poor connection between the trailer and the socket, but poor connections within the lights otherwise. They’re a nuisance! I’d bet it’s the trailer at fault, but the tester mentioned seems a great idea, good luck!

Most trailer electrics are shocking and then there is the abuse they face. There are some attempts to make it more modular and stronger. You can buy a molded cable which has a car plug on one side and two or more light plugs on the other which plug/screw into light fittings all waterproof etc. |

I’ve never come across one! I think they earth through the car. Whenever mine have played up ( often) I find it’s usually the contacts either at the plug or around the bulbs. Bad earths cause some strange things, generally a flashing side light or indicator when the brakes are operating. I’d make sure for certain that it’s not the tow cars socket first, then go from there. |

The wiring on my IW trailer (LM146) is actually very well-designed. It is (as I recall) wired return (so no trailer earth) but there is a reasonably well-sealed junction box at front and rear and it has been properly engineered.
I think, as has been noted above, most trailers suffer from a horrendous lack of maintenance, but if looked after a good trailer, such as an IW or Brenderup etc., should be reliable both mechanically and electrically for years. I suggest that you get underneath and sort out the trailer properly, it will then be good for years. |

IW trailer wiring is normally very robust, the only issue I have ever had is after years of issue free towing with LR130 I then used the Volvo XC60 to tow and the lights were a nightmare, stacks of diagnosis later and nothing found to explain the issues, then I randomly decided to swap the trailer lead around (it has same plug on both end and a 13pin socket on the trailer body) and guess what all the lights worked perfectly, I checked the continuity / pin assignments and nothing found, so I just put it down to the weird mating of a Welsh trailer with a Swedish car.
Long story short, try swapping the trailer lead around! 130 Puma HCPU with an Artica 240LR Demountable Camper |
