Abstract: A cylindrical hollow body fence post disposed according to the present invention features a first closed-geometry longitudinally hollow inner profile interconnected by at least two longitudinally extending bridging elements to a second closed-geometry longitudinally extending outer profile. The tubular post comprises one or more longitudinal housing for receiving illuminating elements. The illuminating elements are powered by a solar panel. The longitudinal housings receiving the illuminating elements are closed by longitudinal coverings providing a dovetail connection with the open end of the housings.

Abstract: A cylindrical hollow body fence post disposed according to the present invention features a first closed-geometry longitudinally hollow inner profile inter-connected by at least two longitudinally extending bridging elements to a second closed-geometry longitudinally extending outer profile. The tubular post comprises one or more longitudinal housing for receiving illuminating elements. Said illuminating elements are powered by a solar panel. Said longitudinal housings receiving said illuminating elements are closed by longitudinal coverings providing a dovetail connection with the open end of said housings. The invention further proposes a method of traffic signalization according to which road signalization is improved on sites where a road portion curves to a direction is visually emphasized by blinking or color changing fence posts.
