A portable, electric morse signalling lamp, used for daylight communications, by the office of the Postmaster General, Melbourne, during World War 2.

This signalling lamp used an external battery as a power source. An adjustable screen is provided (used with a coloured lens) for night time signalling under enemy observation.

Jospeh Lucas Ltd was founded by Joseph Lucas (1834-1902) in Birmingham, United Kingdom, in 1897, as a manufacturer of bicycle lamps, bicycle accessories, and motorcycle and automotive electrical parts and accessories. The lamp design was patented in 1916 by Oliver Lucas (1892-1948), the grandson of Joseph, and was known as the "Lucas" or "O.L" lamp. It was used for military communications during World War 1 and also through to World War 2.
