ABSTRACT:
A combination road construction barrier and marker comprising a generally conically shaped, preferably hollow, upper portion and a generally semispherically shaped base portion. Positioned at the top of the upper portion is a lens-covered light source for nightime operation. The bottom surface of the base portion is flat and is weighted so as to render this invention self-righting in response to strong winds or vehicle impact. One peripheral segment of the generally circular cross section of this invention is flat and extends longitudinally along substantially the entire length of the barrier to prevent excessive rolling in response to external force. The base may include a dry cell battery as one embodiment of a power source to supply electrical power to the preferred electric light source and which is serviceable through a lockable bottom closure. Alternate colored indicia portions may also be applied to the upper portion to improve visibility.
