Post for marking road verges

A verge post for marking road verges and boundaries of traffic lanes, wherein the post has a plurality of flat vertical side faces and side edges and comprises material which will fluoresce when illuminated with ultraviolet light, and when said post is illuminated with ultraviolet light from one direction, said side faces and side edges providing, transmission of visible light from the post, due to fluorescing of said material, in at least two opposite directions including said one direction;

• said post is made from a plastic material, which is transparent to ultraviolet light;
• and wherein at least two of the side faces and side edges are coated with said material which will fluoresce and is permeable to ultraviolet light;
• opposite faces and edges of the post being treated with different fluorescent materials which provide fluorescing light of different colors and in said at least two opposite directions.
