Pilote Motorhome 2018 Rear Light issues

I have a 2018 Pilote P740 sensation.

For some reason there is a strange electrical glitch with the rear LED Lights. These are in sets of 3 one under the other.

Anyway, when i have the sidelights on, and then put on the offside indicator on it causes the nearside sidelight to pulse slightly going brighter as it pulses. The same happens when the hazzard lights are pressed on too. All the rear lights on my MH are LED Strips.

This is causing my Armatige transverse trailer to flash all of its light simutlainously and i mean all.. even the two number plate LED lights. The lights on my trailer are all LED.

I have disconected the input wires from the motorhome via the push in plug to the 7way Bypass Relay, so i know the wiring for the actual towbar is completly isolated ( as if we never the towbar fitted) and i still have this very slight pulsing to the nearside side light when the offside indiactor is active.

Any ideas please?

Looks like a visit back the the Pilote Dealers if not!
