When it's very dark in a room or when getting up at night, it's not always obvious to find the light switch without a nightlight or a torch. Similarly, locating an outlet can also be quite the task. Indicators for switches and outlets have been designed to solve this kind of situation and prove to be very practical in everyday life.
It is necessary to distinguish between indicators and pilots. Indicators emit a light signal that helps to locate a switch. This light is mostly useful for finding the switch in the dark. However, its use can be extended to serve as an alert signal in a potentially dangerous area such as a mezzanine or staircase. Some indicators are designed as crowns, whose brightness brings a unique atmosphere to your home. You can find examples of this kind from brands like Legrand. The pilot, on the other hand, indicates whether the light is working in areas that are not directly visible. This way, you can know from one room if the light is working in the garage, for example, or in the basement. This kind of device is very useful today more than ever from the perspective of energy savings. Moreover, these two types of devices emit light using lamps, often LEDs, which have a negligible electricity consumption.
