Hy-Ko 30600 Series 4-inch reflective house number puts a raised white reflective numeral on a black plastic body so your address reads clearly day and night. The reflective face catches headlights, porch lights, and EMS flashlight beams from approximately 40 feet, meeting community 911 address visibility standards adopted by most municipal address ordinances.

• Numeral: 1
• Height: 4 inches (standard residential address size)
• White raised reflective numeral on a black plastic background for high day/night contrast
• Visible from approximately 40 feet under headlight illumination
• Meets community 911 / E-911 address visibility standards
• Weather-resistant polystyrene body holds up to sun, rain, and freeze-thaw cycles
• Nail-on mounting with hardware included

Where to use: mailbox flags, address posts, house facades next to the front door, garage door frames, fence posts marking driveway entrances, and rural mailbox stands. Pair with matching Hy-Ko letter tiles (A-Z) when a unit suffix (101A, 22B) is part of your address.

Placement Tip: Mount the numerals at a height visible from the street (typically 4-6 feet above grade), clear of shrubs and lighting glare. Group digits with consistent spacing - roughly half the digit width between numerals - and align them against a contrasting background (light siding for the black tile, dark siding for the white-on-black contrast) so first responders and delivery drivers can read the address at a glance.
