Can anyone tell me if there should be a light to illuminate the original Lucas/Smiths style ammeter? The gauge has a heavy bakelite casing with two screws for the charging wires, but no obvious provision for a bulb. It is also a push fit in the dash, with no provision for a retaining clamp (which sometimes holds the bulb to light the instrument face from the side). Was this the only instrument on the dash not to be lit, or am I missing something?
Thanks,
Roger
