Our LED replacement bulb for the common 28vdc miniature flange incandescent bulbs is a guaranteed drop-in replacement for the originals. Unlike similar led replacements offered by other retailers, our lamps are dimmable (reduce input voltage= bulb dims, increase input voltage= brightness increases) and we manufacture them in multiple light colors to give you more application specific options. (and 30% lower price and no minimum order!)
 
Bi-polar power/ground, brighter than incandescent, emits no heat, virtually uses no power and projected life of over 30,000 hours; these are a no-brainer when upgrading your panel lighting.
 
USES: Instrument post lights, Landing Gear Position Indicators, Press-to-test lights, Control panel indicators, flash lights​
 
Replaces bulb numbers: #327, #376 , #387, S3368-2
 
Note: This bulb is NOT polarity sensitive. It will illuminate with both power/ground combinations.
