All fixed, many thanks for everyone's help. It was a sticking switch, caused I think by the fact that the switch had been mounted so far forward in the bracket that every time you took your foot off the brake it tried to shove the button out the back of the switch. Took the switch out gave it some silicone lube to make it work again and then remounted it backed out by about 4mm. It only works right at the end it its travel anyway so it's actually better backed off a bit.
Now have a working brake light, and adjustable clock, a a trip meter I can view and reset

.
Yup spotted the centre push button for swapping to and resetting the trip meter while kneeling down showing my wife the clock controls Peter Thanks for that
I think maybe Morgan need to get someone who knows nothing about the car to drive a car then spend a day proof reading the owners handbook and asking all the questions re the simple missing stuff. It's seems to be written more as a memory jogger for someone who already knows most of the answers. Like, what is the thing that looks like it should be a flashing imobiliser light in the middle of the dash for? I sure doesn't flash
Not complaints or anything just an observation, I actually find the manual quite charmingly written, if slightly thin on the kind of detail we are no used to in owners handbooks now. That said I would rather this than the 2 -300 page tome spread across three thick books that my wife got a couple of years ago with a Merc. there was a short novel just covering the Internet conected Command Control centre in the middle of the dash. Could not be bothered reading and neither could she, so we never really understood how it all worked, never really missed it either

This is at least a manual I have read cover to cover, what's not in there I can discover here.
I am also on a Lotus forum which is equally friendly and helpful, with everyone contributing for the greater good. It seems Lotus and Morgan people have very similar outlooks, a passion for the Make, their and other owners cars and the people that drive them, and a shared enjoyment, a real sense of community now matter how many miles we are separated by.
