The AL indicators provide a two color visual indication of the presence or absence of air pressure in a system. The indicators are available in a variety of color choices as noted in the "How to Order" section. The AL series indicators are fixed two color indicators that change colors when pressure is applied.

These indicators are designed for oil tight panel applications. The rounded lens configuration provide for 180° view of indicator status. These units are easily panel mounted using the same mounting holes as standard electrical pilot lights.
