Hy-Ko Prod Co 5in Black on Yellow Reflective Number #5 | Weatherproof Mailbox Sign

Brighten your address with Hy-Ko 5in Black on Yellow Reflective Number #5

Designed for outdoor readability, this Hy-Ko marker pairs a bold black numeral with a bright yellow reflective field to deliver high contrast under varied lighting. The 5-inch size strikes a practical balance—large enough to be spotted from a car or by a passerby, yet compact enough to fit on most mailboxes and posts without overpowering the space. In real-world settings, this sign helps distinguish your address during evening walks, after-rain drives, or early winter mornings when streetlights spill hazy illumination. The simple, uncluttered design favors quick recognition, so you can direct visitors, deliveries, or emergency responders with confidence, without having to slow down to decipher numbers.

The yellow reflective background is engineered to reflect light back toward the source, maintaining legibility when conditions are dim or when fog, rain, or snow reduces contrast. The black digits stay crisp against the glow, supporting fast, accurate reads at a distance—ideal for late deliveries, curbside pickups, and safety-conscious households.
