The led backlit house number will illuminate your address for outstanding visibility day and night. It features a beautiful satin nickel finish and the latest led lighting technology. This house number is mounted using 1/2-inch stainless steel spacers for a unique floating effect. The led light is projected onto the address plaque or the wall surface. This feature improves the address visibility during nighttime (over 100 feet away) and it gives a nice contemporary glow behind the number. Completely weatherproof and rustproof, it will resist harsh weather conditions.
