GE BULB GE-1940 14V 3.57A

Just a note on this replacement/non original GE GE1940 replacement bulb. Though the description says meeting the same specifications this is not completely true. The glass on the bulb is taller than the original GE1940 bulb (by 1/8 or better). This may not be a big deal on most rotating beacons, but on my original 1966 Cessna 150F Whelen rotating beacon, the bulb glass actually contacted the rotating assembly causing it to make noise as there was pressure from the bulb contacting the main optical rotating shaft once assembled. Good luck. Watch for clearance.
