The headlights are a double switch Lucas toggle 31807E 4388 I think as its small print. (Fuel pump and fan are both single switch 318280 2681.)
The instrument panel dimmer is a rheostat with knob #3R 78405, also Lucas. (Wiper is also a knob type # switch PRS7 54033632)
Horn? Indicator lights are metal, I think FL offers plastic MG type? (incorrect)
