asymmetrical reflector fittings
Described as new in 1932, these were a two-way unit with separately adjustable reflectors which gave accurate light
control, and enabled the maximum candle power to be maintained at whatever angle the unit was adjusted to operate. This was
in contrast to most fixed-angle asymmetrical reflectors where the lantern only operated at maximum efficiency only at one
particular angle.

two-way reflector for open-type conical reflectors
This was an elliptical reflector which could be clipped onto a conical open-type reflector fitting. It was sold as
both an adapter and complete unit. It gave a non-axial two-way distribution with the maximum candle-power being
160° apart in plan - so that the main beams were projected on to the roadway and not wasted on the near pavement.
