It could be water in the 10AS, but that's not connected to the brake lights, so i would think it's just a bad earth connection to the indicators/brake lights. Clean up the earth points and make sure it's sound and the fault should disappear.

Hi Guys, have had both the sockets off and open on the tow hitch and the socket what supplies the feed to the caravan but both sockets look clean and dry and all wiring seems tight and intact, have had off all the rear lights to check for water and nowt !! oddly just noticed as I set the alarm that the number plate light also shows a feed but nothing to the indicators? the indicators work fine as normal as do the rear side lights, will check for the grey plug dorsetsmith and see if thats the problem if I can find the devil?
Many thanks Ole Dave |

Hi Guys, dorsetsmith have had a good look under the rear drivers wing and I cannot see any grey socket ? I did trace the wiring back from where it comes out of the chassis work up to the nearside entry point behind the rear nearside light socket and after some feeling around the blasted flashers worked normally which make it look like an earth problem but where?

There's a fault with the earth to your NS brake light so it's earthing through the other lights, which makes them glow. I'd start by checking the connections in the nearside light cluster, behind the speaker. Darren

Hi Guys, well the lastest weird thing is I plugged the caravan in as a test with the result of no indicators on the caravan but both front indicators on the defender go on full time without switching them on!! have had the caravan plug off again and stripped back the protective sheath as far as I can and nothing evident, all wiring is intact and clean with no water evident, have had all the rear inside panels in the defender off looking for poor earth connections on all the light fittings both left and right, all are clean and seem in good condition, however, I cannot see any direct earth body connections at any of the rear lights at any point to check and clean?
Guess its going to be an auto electrician as its got me scratching my head and the problem has now switched to the drivers side where it was the nearside!!!! where I would look next I just do not know?, I am stumped good and proper. Well thats it guys I am miffed with myself for not being able to source the fault but you cannot win them all !!!! Regards Ole Dave |

dorsetsmith many thanks for the picture of the chassis to trailer harness connection, for the life of me I cannot find the plug, even looking at your picture it does not compute, is it possible for you to explain to an old man exactly where the plug is? while looking for the plug I have noticed up under the rear area looking for the plug that the trailer harness from the socket to the main harness goes over the chassis, at that point it looks like the protective sheath has rubbed away where it contacts the chassis maybe thats the fault? but I cannot get close enough to see if there is damage to wiring loom, if I could unplug the trailer loom from the main loom that would be a great help, but now its chucking it down with rain again so I cannot investigate further today !!!
Regards Ole Dave |

 It can have all sorts of bizarre effects, including some of those you have described. TheThunder Rollsπ¬π§πΊπΈ
