Many of the better makes of luminous tape glow for a pretty long time and they charge quickly. I have a flashlight in my cross-bed box that has a band of luminous tape on it. It is always near the top. Working I open this box several times a day and the daylight makes the tape glow. Even after more than a day in the dark the luminous tape is slightly glowing. Not so much you wold notice in daylight but in pitch-black it shows up well.

Also I have noticed that even after a week in the dark. When the tape has no detectable glow left if I look into the box with another flashlight the tiny amount of light from the flashlight activates the tape. Moving the flashlight across the luminous tape charges it enough so that when the tape is not in the beam the glow shows up.

Of course a combination glow-in-dark and retro-reflective tape would be ideal.
