Snow Scoops Keep Stoplights Clear in Winter Weather
Snow-scoop visors and snow-cone shields are passive attachments on traffic-light visors designed to prevent snow from obscuring the signal. Two main approaches—louvered, vented snow-scoop visors (like the SWARCO McCain design) and clear acrylic snow cones (from Snow Proof Signals LLC)—sit over or inside the hood to shed or vent snow without electrical heating. These durable, maintenance-friendly solutions evolved from early glare-blocking hoods and gas-lit signals to today’s LEDs, improving visibility and reducing snow-related outages.
