7/8 GCBC Rear position light bulb?

[Jay]

I’m trying to find a replacement bulb for the rear position light on a 2011 7GCBC. Just the standard bulb - not looking for the LED upgrade. Photo attached. Google is not helpful. Any ideas on bulb type, manufacturer and/or wattage?

Many thanks.

Looks automotive to me. Remember when all these things were standardized? I bet that sucker is out of a 1999 Lexus, and now costs $150. I would convert to LEDs.

Pull the fixture and search by part number. Looks like you might have a Whelan A555A?

Or, go fishing here. https://www.aircraftspruce.com/catalog/elpages/gereplacement.php



Or ... spend $264 on LED and never change another bulb.

Spruce had LED bulbs at $35. I got two packs at the aviation department of NAPA for $12. Problem is, they are the standard old fashioned bayonet style bulbs. And the Spruce bulb has a flash mode - not unlike these new pesky flashlights that require multiple pushes to get a simple beam of light.

Thanks guys. Ended up getting a Whalen A508 bulb. Available on interlights.com and on Skygeeks. Seems to be right online but won’t know for sure till it arrives.

I could not find an LED replacement bulb that seemed likely to fit.

i appreciate your help.
