See The Manual “Traffic Light” That Was Used In Lagos In The 1940s

The photo above shows a traffic policeman on duty in Lagos in the 1940s.

Note the manual traffic control device in front of the policeman. A side of the device has the “Stop” on it, while the other side has the “Go on” on it.

The traffic official rotates the device to indicate to motorists whether to stop or Go on.
