A bold, high-contrast retro safety sign with a bright red outer border and rounded corners, featuring a pristine white background panel. The top section displays "DANGER" in large, bold red capital letters with thick white outline strokes, flanked by two glowing yellow and black radioactive hazard symbols with red circular gradients and dramatic glow effects. Below the header is a thick black horizontal dividing bar. The main body text reads "LOOK BOTH WAYS BEFORE YOU CROSS ME" in massive, heavy sans-serif black typeface with extreme weight, centered vertically on the white field with precise letter spacing and professional industrial typography. The entire composition is shot straight-on, flat, and perfectly level with no perspective distortion or tilt. Lighting is bright, neutral, and evenly distributed across the surface with no shadows, creating a flat, graphic design appearance. Colors are pure and saturated: pure black, pure white, bright fire-engine red, and vivid yellow. The sign material appears glossy plastic or laminated with subtle reflectivity and clean, sharp edges. The aesthetic is retro safety signage from the 1950s–1970s, rendered as a product photograph with perfect focus and maximum clarity.
