Glow in the dark duct tape isn't just a good idea: it's fantastic. When it comes to using utility tape around the house, the standard grey will do for the the majority of jobs. However, this variation is a phenomenal way to help highlight darker conditions in basements or garages.
If there's one thing about those who like duct tape, it's that they like it a lot. As such, they're constantly on the hunt for the best colors and patterns to help with a variety of uses that not only includes stopping drafts, but for all aspects of everyday life.
The best uses I can think of for the glow in the dark duct tape is to put it on flashlights to make them easy to find in a blackout and to accent fuses with it for easy viewing in low light conditions.
