LED Indicator Lamps

LED (light emitting diode) indicator lamps are a type of LED lamp used to display when a change occurs in an electrical circuit. For example, when something has malfunctioned in an electrical system, a red or orange LED indicator lamp may be used to alert a worker. Other applications include in phone voicemail systems and dashboard lights. LED indicator lamps usually consist of a single bulb, unlike other types of LED lamps such as LED circular arrays

What are the advantages of LED indicator lamps?

Compared with traditional incandescent lamps, LED lamps are much more energy efficient. They also have a much longer lifespan than incandescent lamps. Unlike fluoresccent lights, they do not require a warm-up period after being switched on, reaching maximum brightness instantly.

Types of LED indicator lamps

LED indicator lamps come in a variety of different colours depending on your needs. They also vary by the intensity of the light produced, by size, and by longevity.
