Tip: Head to your local hardware store and find the 'babyproofing' shelf. You can find glow-in-the-dark (GITD) plastic fobs, intended for pull-cords of overhead lights and ceiling fans. But the big find is the cheap rolls of GITD tape. A single wrap around a toolt makes it highly visible. This stuff has improved from the weak and short time glow they had in the 70s.

Even when it isn't 'charged' it still helps. To find something with GITD tape on it shine a light around where you think it might be. Then turn off the light. Just the exposure for the beam of a flashlight is enough for the tape to glow for minutes. On a dark night even a weak glow stands out.
