To be honest I really haven't a clue, is it easy to revert to standard lighting format if it makes the mot a problem.
Since its belting it down with rain here it has also developed a water leak I believe from where the boot joins the top of the car, could be where the cabling goes in & rubbish has perished?.
Steering seems better now I sorted out tyre pressures, I can't work out how to turn on/off the airbag to eliminate the error light.....any clues?...what does it look like?
