An L.E.D. light assembly for traffic arrowboards having an upright oriented lens having a front surface and a rear surface. A plurality of vertical flutes are formed on said rear surface and a plurality of horizontal flutes are formed on said front surface. Each of these flutes have a left edge and a right edge and when the lens is viewed from the front or rear, the respective viewable intersecting left and right edges of the vertical flutes and horizontal flutes define a grid of four-sided light magnifier modules. This grid has a central core portion of light magnifier modules and a surrounding portion of light magnifier modules. Light from the L.E.D.'s positioned behind the central core portion of light magnifier modules produces a spotlight type of beam along the longitudinal axis of the light assembly. The surrounding portion of light magnifier modules produce a divergent light pattern that is greater in the horizontal plane than in the vertical plane. The light intensity in front of the central core portion of light magnifier modules is at a minimum of 30% brighter than the intensity of the light in front of the surrounding portion of light magnifier modules.
