Small markers, many uses …

Slumberlights key fobs and dog tags are the same 1.25″ photoluminescent discs (two layers of glow sheet around a cork core). They charge in ordinary light and give a brighter green glow for about 15 minutes, then a soft, usable glow for up to 10 hours. The main difference is the ring: the key fob uses a stronger, double-coil steel ring so keys and other items stay secure. The dog tag uses a lighter safety ring that lets most dogs pull free if the tag snags.

The base of both the dog tag and the key fob showing maximum glow

Here are some practical places to put them.

• Around the house and pets

• Attach the dog tag to a your dog’s collar so you can see the dog sleeping at night and avoid stepping on it.

• Keep one on your main key ring so you can find the keys on the nightstand, in the grass, or in a dark hallway without turning on bright lights.

• Clip one to a flashlight so the light itself is easy to locate when the power is out.

• Hang one on the breaker-box door or handle so you can find the panel quickly during an outage.

• Put one on the zipper or handle of a first-aid kit and another on a fire extinguisher (or its bracket) so emergency gear is visible in the dark.

• Emergency and everyday items

• Keys to a gun safe, case, or lockbox

• Emergency go-bag, outdoor kit, or spare set of house keys

• Gym bag, laptop bag, or medication organizer

• Camping gear, toolbox, or shed door

• Leash or harness for nighttime walks

They work as passive “lighthouse” markers: just enough light to show where something is, without lighting the whole room or needing batteries. One on everyday items, plus a couple on emergency gear, cover a lot of nighttime situations.
