M22 Led which is often used under translucent switches to indicate the status of the switch. Or it can be used in combination with different m22 lenses, to make a signal light. The LED is available in 3 different colours. White Green and Red. In combination with the type of LENS used different effects can be achieved. We often use a white lens and then a green or red LED. This make a real change in colour from white to red or from white to green. Other option is to match the colour of LED and LENs, than a more intense RED White or Green can be achieved.
