A highway guard rail device (10) that warns and delineates through reflex reflectivity of sunlight and vehicle light back to the motorist. The main body of the device is made of protective coated (24) metal (22) with retro-reflective sheeting (20) adhered to the front surface of the device (10). The device (10) mounts onto and covers the full vertical height of a W-shaped highway guard rail (28). The device (10) comprises of a relatively flat front face plate (14) and two contiguous convoluted concave protruding ears (12) on either side of the face plate (14). The ears (12) are positioned in the guard rails (28) U-shaped recessed trough (30). The reflective convoluted concave ears (12) and the reflective flat front face plate (14) provide a lateral reflex reflective surface angle of 0 degrees to 180 degrees. The device (10)is secured to the highway guard rail (28) by sets of opposing fastening tabs (16) which are contiguous part of the main body face plate (14). There are fastening tabs (16) on the top of the device (10) and on the bottom of the device (10). The pair sets of fastening tabs (16) are bent over the top and bottom of the guard rails edge (32) respectively. Cable tie fasteners (26) are threaded and buckled through the opposing sets of fastenings grommet tab holes (18). The cable tie fasteners (26) are pulled tight fastening the device (10) in place and in shape against the front facade of the highway guard rail (28).
