Why We Created Slumberlights
We were parents of two young boys who spent years navigating midnight feedings, dark hallways, and Lego minefields. Bright nightlights kept waking us (and the kids). Regular glow sticks weren’t reliable enough.
We needed something better: soft, purposeful markers that would guide us safely without disrupting sleep.
That idea became the SlumberLights Nighttime Navigation System — small passive beacons inspired by how lighthouses guide ships through the dark. Just enough light, exactly where you need it.
Today we make simple, durable glow markers so families can move safely through the night and still get the rest they need.
The mariner does not need the entire coastline lit to find his way in the dark. That’s what lighthouses are for.
They get the ship from one to the next safely and without incident. That is exactly what the Slumberlights Safety System does.
Sold in packs of four. Buy as many as you need to light your way around the obstacles in your home.
Slumberlights takes takes advantage of this approach. Inspired by how ships navigate foggy coasts, the lighthouse method uses small, purposeful glowing markers as beacons ….

Glowsters glow-in-the-dark lightweight nightlights provide just enough light all throughout the night.
Soft, non-disruptive glow that guides without waking the brain. Charges in 15 minutes of light; glows 10+ hours, fading as eyes adapt.
Soft green glow provides just enough light for kids, seniors, parents, and midnight navigation.
