SHOP NOW! Highly visible glow in the dark house number signage plaques to make your house pop out in your neighborhood! Your friends, neighbours, delivery guys, and guests will thank you for installing GLOWTEN.com glow in the dark house number signs so they will never have a hard time looking for your house number during those dark nights. Our green warning house number signage plaques are made with new high performance grade photoluminescent pigment material which require no power so they are very environmentally friendly and they will retain their light charge for a couple of hours in the dark when exposed to daylight or indoor light. The more light that is absorbed, the stronger and longer the glow will be in the dark. Other than for personal and home uses, GLOWTEN.com House Number Signs can be used in office buildings, grocery stores, hospitals, schools, factories/warehouses, traffic signage and train stations. We look forward to your industrial needs, special projects and wholesale inquiries.
