safety light
Warning glow device
A safety light is any light designed to prevent accidents or signal hazard.
In photography, it refers specifically to a dim light used in darkrooms—typically red or amber—that allows visibility without exposing light-sensitive materials: She worked under the safety light while developing prints.
Safety lights also appear on vehicles, construction sites, and emergency equipment.
