A portable warning sign comprises a sign panel 34, at least one warning light 8 and a housing 3. The sign panel is movable from a position in which it is contained in the housing to a position in which it extends from the housing. The sign panel is preferably formed as a roller sign (Fig. 2) comprising a flexible panel attached to a spring loaded rotatable spool for automatically retracting the sign panel into the housing. A handle 36 may be provided for extending the sign panel. The warning lights are preferably formed from LEDs powered by rechargeable batteries. LEDs may also be incorporated into the sign panel. The sign may be mounted on a tripod type stand 68. The sign provides an effective warning sign for motorists. |
