reflector, and the relationship between the filament and the base of
the bulb isn't necessarily consistant from one bulb to ahnother. These
aren't "pre-focused" bulbs as were used in latyer Lucas units.
The adjustment isn't really that difficult. Take the reflector out, loosen
the socket clamp, turn on the lights, and aim it at a wall. Move the
socket in/out until you get the correct light pattern, then tighten the
clamp and reassemble the light. The light doesn't have to be completely
reassembled between each adjustment attempt. Just hold the reflector in
your hand and aim it at the wall.
