Brand new still in box part number WLA7512-24 / M6363/2-2 Nav Light bulbs.

$35.65 on Aircraft Spruce, $54.63 list price at Textron (you may get them for $35.51 if you have the right discount). Of course you pay shipping with either Spruce or Textron.

First $40 takes both, and I'll pay the shipping. Or will trade for a like-new bottle of Green Spot or Red Breast 12.

I used to keep a couple bulbs handy in my AOG kit, but just went all LED.

Sold. (Well actually I just gave them to a friend with a Bonanza who needed them).
