You are confident that bulbs in the high break light are working and not the case that all of them are burnt?
After the initial repair, the light did come on but then went out again!! I will double check the wiring Sunday, the rear spoiler is off and we can get to the plug and wiring!! @Antony Parsons has already polished under the spoiler….
He's been a gent today and not only cleaned up some of my internal trim like the visors, but he's also working on a good polish up of my sill extensions! EDIT... plus he's really brought up one of my rear lights!
Funnily enough, that silver Mynheer kitted R3 on the MGCC stand is actually a Rover 200. It's lost the Mimbari rear spoiler, too. The amount of times the MGCC wouldn't let my 200 near their stands because it wasn't an MG...
And finally!! A shorting wire in the tailgate connector at top of the tailgate and most importantly a corroded wire in the actual light itself which we have cleaned as best we can but may require a replacement light in the future!
