Back lights on the Dmax have gone mad.

I think that you will find that the rear lights are controlled by one of the cars computers and the globes have different brightness by sending a different frequency to the filament instead of a constant 12 volt supply of old. Your car should still be under warranty so the dealer should be the place to go. don't you just technology

Unfortunately Murray isn't quite on the mark. The electrics for the lights have no electronic control.
However, they do have normal current flow to the Park light wire and the Stop light wire and also there is an earth for the trailer all via the plug. Earth is near rear of spare wheel.
If yours is a genuine tow bar then the wires for the left and right flasher go to two dedicated relays which receive the normal flasher signal and feed it to either of the coils of the two relays as required. Supplies both when hazards are on.
There is a full time power wire provided in the loom, and the towbar loom plugs into it and all the signalling wires receive just a signal supply.
When the left or right flasher is activated, the flash signal goes to either of the two relay coils. The relays then switch power from the supply wire in loom to the trailer plug and this is done so any load of the trailer will not alter the flash rate and does not overload the flasher system because on the trailer you might have 1 flasher globe or as many as or more than the vehicle has.

Because your tail lights are being activated it would indicate a connection fault in the trailer plug, ie wire strand touching from left or right flash to brown or red wire.
If the loom has been damaged from your robust offroading then the cable may be squashed and this has effectively shorted the wires together.

In addition to the normal wires in the plug, it also has two extra side terminals which are used to disconnect the reverse sensor earth system ( if fitted) while towing. There is a magnet in the lid and this only connects the reed switch for reverse sensors when the lid is shut.

G/Day BooBoo, Its annoying ! and you don't know until someone points it out, Hopefully not the law!, .. With the Defender this sort of thing has drove me nuts over the years, always a connection or earth....SOMEWHERE!. Quick Fix,......Maybe a bigger Hammer..lol.

Cheers Axle.

G'day fellas

Thanks for all your replies.

The culprit was the scotch connectors they used to connect the lights to the pod.
They were not doing their job.

This has been a very intermittent fault from the time I had the pod fitted 12 months ago, maybe once a month, it is only in the past few days it became frequent..

I had taken it back to the manufacturer a few times but they couldn't find the problem.

I thought it had resolved itself until last Sunday.

The auto electrician in Quirindi was kind enough to fit me in this afternoon and found the problem straight away.

The Dmax acually produced the problem when he turned the blinkers on, yet the day before I just couldn't get it to produce the problem

He removed all the connectors soldered the wires together and Bob's your uncle.

You need to check fuse they might have blown away
