The "Lucas Lamp" was invented and patented by Oliver Lucas in 1916. Many were made by the infamous Lucas Industries lamp manufacturer Joseph Lucas Ltd. or J.L Ltd of Birmingham, UK. However, signalling lamps made by other companies were still referred to as "Lucas Lamps" or "O.L Lamps."
The following image is a schematic of the original O.L Daylight Signal Lamp.
