Any advice appreciated. On collecting our 2015 Troll from AL the fog light (red) and reversing light (white) worked the opposite way. In other words when the fog light on the car was switched on, the reversing light on the van came on. When the car was in reverse, the fog light on the van came on. We have been to a reputable trailer centre who offers to fit a new module to the car but also said the wires 2 and 8 might be round the wrong way on the van. They said if we switched the wires over on the van ( 2 and 8) it could damage the new module on the car, but if we leave the van as it is, how will the new module work if the wires on the van are round the wrong way. I don’t really want to spend money only to find the problem is not solved. Thank you

AL should cover any fixes under their warranty. Just let them know and they will direct you to an authorised fixer. You won't need to go back but let them say who should fix it.

We have the same issue, but as we spend the vast majority of our time on the continent we have let it as it is.

The OP doesn't say if the lenses are fitted correctly ie is the clear reversing lens on the nearside and the red lens on the offside. If they are then somebody has swapped the lenses over on a Continental spec. van but hasn't swapped the electrical connections at the junction box. On the other hand, if the lenses are the wrong way round, then the electrics have been swapped but the lenses haven't.

For the avoidance of doubt, in the UK the red fog light should be on the offside corner to mark the corner nearest passing traffic and the clear reversing light should be on the nearside, illuminating kerbs.

it is amazing how may now have a centre fog though

Are you perhaps confusing the 'high level brake light' with the 'high intensity poor visibility light'?

No. We aren’t confusing anything. Everything is where it should be. It seems the wires crossed. 😁

It sounds to me that if the lenses are the right way round then the original converter forgot, or couldn't be bothered to switch the wiring. Presumably AL would've taken it on face value that as the lenses were right, it had been converted.

The moral of this story, dont go backwards and dont drive in the fog, and the central fog lights are too low down to be brake lights

That’s a good idea! 😁

It's a 10 minute job to swap the wires over. Just check the Eriba manual and standard tow plug wiring convention for details.
