Good afternoon. I have been making and restoring Austin 7 lights since 1974 and spent the kid's inheritance on original Lucas documentation.
Headlamps.
1922 - c 1924 CAV bell shaped headlamps, 5"
1924 - 1928 Lucas R510 scuttle and for a brief period forward mounted 5" No pilot lamp.
1928 - 1931(2) Lucas R47 6". R40's were never fitted to A7's. Single filament bulbs. The first RN's were supplied with R47's fitted with Lucas - Graves dipping filament bulbs and reeded glass. Pilot lamp fitted.
1931(2) - 1933 Lucas Type 35/32. The 32 referrs to the angle of offset to facilitate wing mounting. Reeded glass. Pilot lamp fitted.
1933 - 1934 Lucas LB130. Flat Diffisa glass, N/S Dipping solenoid mechanism. O/S off when dipped, on when on main. Pilot fitted.
1934 - 1936 Lucas LB130. Curved Tear drop glass, dipping as above. No pilot
1936 - 1939 Lucas L131, and later 133, a more pointed shell with glass and dipping as above. No pilot.
Sports models had the same profile lamps but were verticall mounted.
Side lights
R510's were wired such that their single filament bulbs were in series 3v when on 'side' and parallel when on 'head' 6v.
1934 - 1935 Lucas LD 108. with a reeded effect glass. Twist on rim
1935 - 1939 Lucas LD 109, screw fitting rim, reeded effect glasses appear to have been phased out over the period.
Oddly all the glasses are marled LD 108.
E&OE. I am always happy to be advised differently.
Regards from the creative county Staffordshire.

The 1931 (2) -1933 Lucas Type 35/32 were fitted with the Lucas/Graves twin filament dipping bulbs.
