A portable traffic-light signal (10) comprises a traffic-light head (12) and at least three extendable legs (14). Each leg is movable between an in-use position in which the leg is extended and projects downswardly from the head so that the legs are splayed and the head can be stood on the legs on the ground, and a stowed position in which each leg is contracted and does not substantially project in its longitudinal direction from the head. By employing at least three legs, the signal can readily be made more stable that if the head were supported on a single pole. By employing legs that can be extended and contracted, the signal occupies little space when being transported or stored, and yet can be made so that it is easy to set up. Two such signals (10, 40) are provided in a set and have means (42, 44, 46) for connecting the heads together in a stowed configuration so that the front face of each head is covered by the other head to portect the front faces of the heads when not in use.
