A temporary traffic signalling system, comprising at least two signalling light display units (1), each having a wireless receiver (50) connected to a display controller. A system controller has a wireless transmitter (39) and manually operable controls selectively operable to transmit a control signal to change the state of a selected one of the display units from displaying a stop light signal to displaying a go light signal. Each display controller is configured to display a stop light signal unless a control signal for the signalling light display unit is being received. The system controller comprises a reset button, operation of which causes termination of signal transmission by the wireless transmitter, and is further configured to prevent a user from causing a further selective control signal to be transmitted until the reset button has been operated.
