Just fitted a new socket on the back. The old one was rusted. Have carefully checked all connections and everything works except the nearside rear light. Can't see any obvious break so must be somewhere in the loom and I do not have the expertise to find out where.
Would it be possible simply to run a wire across the back of the socket from the rear offside light connector to the nearside one or would this be a recipe for disaster.
Possibly, I think the left and right are on separate circuits and fuses, doing that would effectively join the two. Does the left rear lamp on the car still work?
The left/right rear lights on the trailer socket (12N) are different circuits carried on pins 5 and
The rear (fog), reversing, brake and indicator lamps all work and what I had in mind was running a wire between pins 5 and 7 so that the power obviously getting to one rear lamp can then be transferred to the other
It's a case of wanting to know if this is possible
Theoretically possible, but as has been stated by a previous poster, this would connect the two previous separately fused lighting circuits and I wouldn't like to predict what would happen under fault conditions! Also bear in mind you would be running a further 5 lamps (on the caravan) off that circuit.
It shouldn't be that difficult to find the feed to the rear tail lamp. What vehicle is it?

There will be no problem if the link is made on the back of the socket and the non-working wire is left disconnected. The only thing to check is the rating of the fuse and the wiring is capable of handling the one extra lamp.

I forgot to add, I assume that you have checked that the fault is not in the plug or wiring to the trailer lamp.
Jeff
It's not one extra lamp though is it? Or am I getting confused?
If you link those two wires on the back of the socket the working (car) sidelight circuit will then be feeding on the caravan:
2 x rear lights 1 x number plate light 2 x white marker lights at front.Cheers
Peter
If you link the 2, you than have the scenario, that just one further fault would leave no lights working on the caravan,
I have always worked on the theory that the seperate feeds mean that if one circuit fails you would still have one rear light working ,,
I assume you have checked the earth on the offending lamp.

Both of em?
Checked the bulb?
Checked the bulb?
Thanks to all for the advice
I think the best and safest solution is going to be finding the fault in the wiring - the trailer lights work properly on another vehicle so it must be mine
