*This model is intended for indicators and annunciators
LED equivalent bulb for 28-Volt Single-Contact, Midget-Flanged filament bulbs, compatible with both DC and AC electrical systems. This led is optimized to focus the light outward, and thus most suitable for retrofitting press-to-test indicators, and other annuciation applications. This model is NOT recommended as a replacement for post-mounted panel flood lights. This led is not sensitive to polarity and is dimmable (reduce input voltage = bulb dims; increase input voltage = brightness increases).
Multiple light color variations to give you more application specific options. Virtually no heat, 75% less current consumption and projected life of over 30,000 hours. This is a simple, low-cost and long-term solution to more efficient and more reliable lighting compared to the inefficient failure-prone incandescent variants.
Hint: General rule is to match the light color to the lens color for indicator application.

Reviews
The lights work perfect and do exactly what they are supposed to do. On a night flight my co-pilot was complaining about the gear indicator lamps being too bright. I'm going to do the Sharpie trick to block off some of the light.
Next, one of three landing gear lamps failed after one flight. No answer to the phone number and no reply to my email.
