    The GDL 82 UAT has an output pin on the connector that's an open circuit if the unit is transmitting all the required ADS-B data properly, but provides a ground if something is amiss. I'd like to find a small square 14 VDC LED indicator with a built-in DPDT momentary switch that would provide a momentary ground to test the LED while isolating the GDL 82 output pin during pre-flight.

    Has anyone had any luck finding such a beast? I can make one easily enough using a panel mounted LED and a separate momentary switch, but it would be nice to combine the indicator and switch in an off-the-shelf unit.
