A portable traffic control sign that includes a lightweight sign head selectively attachable to a lightweight pole. The sign head includes a thin interior frame sandwiched between two opposite facing, traffic sign panels. The interior frame includes an octagonal outer support structure and an inner support structure. Attached to the opposite surfaces of the outer and inner support structures are two arrays of LED bulbs. The two sign panels each include a thin transparent window. When placed on opposite sides of the interior sign frame, light from the first and second array of LED bulbs is able to be transmitted through the two windows exteriorly. In the preferred embodiment, each panel is made of DOT approved retro-reflective material. The two arrays are connected to a main control unit mounted inside the lightweight pole which also contains the battery pack and optional flasher switches.
