A tri-colour indicator contains two different coloured LEDs. As standard the two LEDs are symmetrically illuminated, giving a mixed light output of the two colours. The best way to understand how this works is like mixing paints. For example, a combination of red and green gives the colour yellow. If the two LEDs were red and green, the colour of light emitted by the indicator would be a bright yellow. . Why choose LEDs? LEDs have many advantages. Long life and low power consumption are the main features, but there are many other reasons as well. Temperature LEDs generate much less heat compared to incandescent or neon lights. Directionality LEDs emit light in only one direction, reducing the need for additional components such as reflectors. However, this is not the case when the LED indicator is used as a signal on a circuit board. . Do these LED indicators come with the appropriate fixings? Each indicator is supplied with a fixing nut, washer and gasket.
