"ADS-B FAIL" panel mount LED indicator with "push-to-test" switch

[Stan Cooper]

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.

Does this do it?

Not a square one https://lonestaraviation.com/product/panel-indicator-dimmable-14v-red-ls03-07100-14/

most square ones I see are marketed towards transport category aircraft, have the text on them, cost hundreds of dollars, and no built-in switch.

Brian, I think you struck gold. That's perfect!

Thanks for the tips, everybody.
