The unitary structural body has a base surface partially sealed with a compatible sheet includes exterior surface with multiple protruded grooves. An alternative structural body can have a sealed base surface including multiple protruded and recessed grooves with at least one inclined face having a recessed area for receiving a pre-formed lens plate attachment. The planar base surface of said unitary structural body includes an impact absorbing hollow cavities extending along the sides of the inclined reflective faces and incorporate multiple of protruded rectangular grooves. The structural body can incorporate various pigmentations or luminescent colorant compounds such as compounds containing thioxanthene dyes or phosphorescent pigment such as strontium to provide fluorescent self emitting light after glow to improve day and night visual display when illuminated with light within the ultraviolet wavelength range.
