For completeness, this is what Lucas finally settled on post war.
Brown means live all the time (=connected to the battery post)
White means brown that has come through the ignition switch and can therefore be switched off with a key (coil, fuel pump)
Green is white that has gone through a fuse in the fusebox and is therefore (like wipers) switchable and fusedBrown
Purple is brown that is fused and therefore permanently live (horn and interior lights plus radio)
Blue is lights. Power comes from the brown to the switch so that lights can be switched on whilst the ignition is off. [Note. sidelights (red) are fused but headlights are not.]
The supply from the headlamp switch is blue as far as the dip switch where it goes to blue/red for dipped and blue white for high-beam. From the switch it is red/green until it reaches the fusebox where it becomes red only. The panel lamps are red into the switch (comes on when the sidelights come on) and become red/white as they travel to the individual bulbs
white/black is from coil to dizzy plus to RVC type distributor.
Black is earth.
green/red is right indicator
blue/white is left indicator
green/black is fuel tank sender
green/purple is brake lights (therefore fused and comes on after the ignition is live)
