Great replacement bulbs for Piper Arrow II landing gear indicator lights.

BI-POLAR MINI LED REPL T1-3/4

January 25, 2022

I bought 10 of these several years ago to put into the buttons of our Continental 816R and QEI FMQ 10,000 transmitters. They remain bright and steady all these years later. The bipolar nature and wide voltage range allows these bulbs to operate well no matter what socket I put them into on these transmitters. The transmitter manufacturers basically told me I was SOL when it came to replacement lights, but Spruce had these and Im buying more now to try in our Wheatstone Audio Arts R-60 consoles. Im hopeful at the 5 Volt level, the light will be as nice as the original LED lights the console came with 25 years ago. For 30 Volt use, though, I think this is the ONLY choice for your T1 3/4 replacement. And the price is one of the best on the internet for any LED bulb of the miniature variety. There might be rare cases where these bulbs wont work, but Ive had them work fine in AC or DC sockets from 24 Volts to 28 Volts. They stay bright and steady and dont flicker or do unpredictable things in push button actuator switches on these transmitters. The old incandescent ones were always flickering or burning out within a couple of months. These are well worth the try.

These are an excellent replacement for the original bulbs. They are very bright and low energy draw. Makes it easy to see gear position during the day.

Q: How much current do the part #11-09629 LED replacements for the 330 12V bulbs draw? Will they work with an instrument panel dimmer? On the same dimmer with standard 330 bulbs? Thanks Will

Per the manufacturer, 11-09629 draws 20 milli amps. Yes, will work for the instrument panel dimmer, but will not dim very much on these standard bulbs.

Q: Are these LED midget flange based bi-polar lamps PMA'd for certificated aircraft?

Per the supplier: No, these are NOT FAA PMA'd for use in certified aircraft.

Q: Why are these not intended for use in post lights?

This statement is from the Manufacturer. As this is not FAA approved they would not like theses installed as post lights for certified aircraft. If you have an experimental aircraft you have can install these as you please.

Q: Are these supposed to be the bright white LEDs? Mine are yellow in color and wonder if this is correct?

The LED midget flange lamp (11-09629) is a warm white which has a slight yellow tint to simulate the color of an incandescent bulb.

Q: How bright are these LEDs? Typically the spec is in mcd or lumens. Thanks!

These are 20mA and 500fcd
