Road light problem with Bailey Unicorn Vigo

I wonder if anyone else has suffered this problem, which I have only just discovered on my 2019 Bailey Unicorn Vigo.

I tow with a 2017 Audi Q5 and have only just discovered a problem with the near side running lights on the van when they have been on for around 20 minutes. The car gives a warning that a bulb is out on the trailer. On checking all the near side running lights are off, but the indicator and stop lights still work. Having been stopped for 5 minutes on starting up again everything works as normal for 20 minutes then the same thing happens again.

On searching the internet I have found that the same thing has happened on Swift vans and that it is caused by the car testing the light bulbs and because the side running lights are LEDs it triggers a fault. The electrical company Sargent who provide the electrical wiring for Swift have produced an update which solves this problem.

Have any other Bailey owners come across this problem?

Thanks.
