UK mot

On a 1973 st70 do you have to have indicators for a UK mot
At moment I just have front and back lights, brake light, and speedo.

No need for them, but if they are there they have to work.
So if you have them and they dont work, take them off for the MOT

I do have them but I no switch or relay any advice on fitting a switch and relay. I have seen relays on ebay but no switch And also am confused about where the wires connect from switch to relay to indicators and how to connect up

Dropped the idea of indicators for the time being.
Do you have to have front break cable attached to the loom for the brake lamp at the back or can you just get away with the back one?

They both have to work.
