Indicators are a great alternative to single LEDs, and these small components are responsible for signaling the device status. If you need an indicator for your project or a device, check the large selection of products available at We sell LED-based indicators available at different sizes and colors, so you will certainly find the model that suits your needs. There are different kinds of indicators. For example, a power status indicator (or the on/off button indicator), which can be placed on the front of the device to provide power and system status information. According to the device status, the indicator will signalize fitting information. Another example could be a hard drive activity indicator, which also can be placed on the front of the device. This indicator will provide information on the status of the hard drive. As you can see, LED-based indicators are essential elements of each project. Browser our catalog to find the indicator that will meet your needs. We assure you, that offers the largest selection of high-quality LED-based indicators. At our shop, you can buy indicators online with fast delivery.

Power LED indicators

LED indicators are industrial control production components that are usually installed to signalize the status of a certain device. Indicators can be very helpful while diagnosing a device and are essential in some projects. Their help in diagnostics and also they provide a safety feature because when you see a LED indicator lit, you know that the unit is powered.

However, you shouldn’t assume that the indicator works properly when you test a device for the first time. Always remember to double-check that. When choosing proper controller type equipment for your project, always remember to pay attention to the type and value of the power supply. Some LED indicators are adapted to work with 230V alternating voltage - such indicators will be an excellent alternative to small light bulbs or neon (gas) indicators. Some indicators are designed to operate with lower voltages, most often 12 V or 24 V - some of which can only work with direct voltage, while others can be powered by both an alternating (AC) and direct (DC) signal. The most common controls are based on LED diodes, which, compared to the bulbs used in the past, ensure incomparably greater reliability and often lower power consumption. Thanks to the use of LEDs, the lights can have different colors - it makes it easy to choose the right color,

Controls with neon lights

Indicators with built-in neon lights were a popular solution many years before reliable and cheap LEDs appeared. Small neon lamps were and still are used in wall switches "with a lamp" and illuminated rocker switches. However, it should be remembered that the neon lamp can only light when it is supplied with a sufficiently high alternating voltage; connecting it to DC voltage will not turn it on. For this reason, neon lamps are nowadays mostly used only to indicate the presence of 230 V mains voltage. However, in such applications, they are still a good, cheap, and reliable solution. As with LED indicators, the most common form of connectors used to connect these elements are connectors.

Optical-acoustic controls

An interesting alternative to ordinary optical indicators, especially useful in alarm and warning applications, are indicators with a built-in buzzer. Due to the alarming nature of the application of such elements, you will most often find them in red. In this category, we have made available three versions of 28-mm indicators with a built-in acoustic signal - one is designed for 12 V DC, the second - 24V DC, and the third - 230V AC.
