Size: 1" Dots/Circles -in-the-Dark Tape Dots can be used to make steps or the rungs of ladders more visible. Perfect for use on stages where lights are quickly turned off, leaving a group of performers to exit in complete or partial darkness. Can also be used on objects such as forklifts, racks, barrels, or anything movable that might be in an unexpected place to warn people who are moving through the area in low light situations, especially within an hour of lights going out. This tape is not a replacement for adequate lighting and should not be used as a replacement for light, but instead as an emergency backup or in situations where full light would destroy some critical aspect of production such as in a theater or while using photo reactive chemistry to develop photographs.
