The invention relates to a winding device (8) for an electric cable (4, 4a, 4b) including a cylindrical hub (62), perforated (622) at its surface and open (624) at at least one of its ends, the cable having at least one conductor (41, 42, 43, 44) and a sheath (45, 45a, 45b) with an outer surface having an irregular cross-section.

A traffic control light strip supports a plurality of light emitting diode illumination devices within a plurality of LED units upon an elongated supporting strip. A power and control unit responsive to operator inputs is operatively coupled to the LED units to provide selective illumination patterns of the light emitting diodes. The traffic control light strip is supported by a flexible elongated base member which allows the entire traffic control light strip to be rolled upon a storage reel from a deployed configuration to a convenient storage configuration. In an alternate embodiment, the traffic control light strip includes a pair of extendable hinge coupled support members that facilitate folding the traffic control light strip to a closed transport and storage configuration.
