Saf-T-Light is a battery-operated hand held sign that provides backlighting to a warning or instruction message. The preferred embodiment of the invention utilizes eight fluorescent light bulbs powered by a battery and attached to an octagonal frame having a handle and translucent panels with stop and go messaging for attachment to the frame. To use Saf-T-Light, an individual installs the batteries into the handle of the device and the appropriate translucent panels into the frame of the device. The user can then turn on the power switch on the handle and show whichever side of the frame is necessary. For example, the Stop panel will be shown when traffic or crowd flow should cease and the Go panel will be rotated to be shown when traffic or crowd flow should proceed.
