LED Press to Test indicator features a dimming actuator, LED replaceable lamp, and an amber lens. Military grade panel mount indicator meets or exceeds military specification MIL-L-3661B with high quality black anodized aluminum housing.
The 24V LED is easy to installation and compatible with a 24V electrical system. If you do not have an EFIS to connect to, this is a required indicator light if installing in a certified aircraft along with the ETX680-24-TSO battery. Detailed installation directions are located in the EarthX manual but it is very simple. To install, connect red wire to a positive bus connection, connect the black wire to the EarthX battery.
The positive wire (red wire) of the LED should be connected to the electrical bus (24volt positive), typically to a fuse/breaker downstream of the master switch. The negative of the LED (black wire) should be connected to the fault monitor wire (wire out the side of the battery) of the battery.
Step 1: Install the 24V LED light thru a hole in your control panel.
Step 2: Connect the 3-pin plug from battery into the 3-pin plug from LED.
Step 3: Connect the red wire to an electrical bus fuse/breaker (.25-1 AMP). Most of the time it is most convenient to connect to a fuse on the back side of the panel. If not, it could also be connected directly to the positive terminal of the battery with a ¼” ring lug connector.
