LED Midget Flanged Bi-Polar Lamp
T1-3/4 (5-28 volts)
A direct LED replacement for Midget Flanged Based miniature incandescent lamps. Long-life, low power consumption, shock resistance, and extreme thermal tolerance make LED's ideal for harsh industrial environments. Voltages from 5V-28V AC or DC.
Replaces miniature lamps:

Excellent product. Exactly what I needed, where I needed it, superb shipping and reasonable price.
Very Good. Just as I ordered.
These LED lights are brighter than the incandescent bulbs they replaced. In my case, I have bulb cases with adjustable eyes, so Iâ€™m not worried about it. You can see these LEDs better in daylight. The incandescent bulbs got very hot, but the LED lights are cool. The LEDs should last much longer than the incandescent bulbs.
The reason these lamps will not work in a compass is because a compass light fixture is wired backwards than a normal fixture. This is due to the way the lamp is inserted in the fixture. The positive post in a compass fixture is inside away from the frame, and touches the outside circumference of the lamp (normally the ground). The ground is the cover over the lamp, which touches the center lamp electrode. If it was wired conventionally, you would touch the case and get a shock. LEDs are polarity sensitive.
This was the only site I found that carried an LED lamp of this shape that was described as being a bi-polar lamp. The new lamps fit well and have worked in all our applications on broadcast equipment panels.
These bulbs are an excellent replacement for the GE 330, but be aware that they will probably overwhelm green or amber lenses. All I can see thru my amber warning light is a bright white. I dont usually fly at night so this is fine. My amber warning lights are not the dimmable kind. I have a dimmable red lens warning light, and the red shows ok and the bulb seem to dim.
Work great in Continental 616R series FM transmitters as direct replacement for the incandescent midget lamps in the filament on/off and plate on/off buttons. They are super bright, so only one bulb per button is needed, even though the button frame will accommodate four per button. These also work great for the panel lights in a QEI FMQ 10,000 transmitter! Super versatile, super bright, super cool and the price is super right.
Plenty bright as a 327 replacement in a 28 volt system. Doesn't appear to generate as much heat as the original incandescent lamp.
Used as a replacement for GE-330 12V landing gear indicator lamps. Brighter than the incandescent lamps, not sure if they can be dimmed or not, mine stay full bright.
Much brighter in my original landing gear down indication bulbs. Now I can see the lights even when the sun is shining on it.
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.
Per the supplier: No, these are NOT FAA PMA'd for use in certified aircraft.
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.
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.
