Anyone know the size of the steaming light festoon bulb? Not finding it in discussion topics or the manual. Replacing my incandescent with LED. I can climb a ladder and investigate, but I thought I'd ask the collective brain trust for a replacement part size / model if anyone knows...

I found these 12v A15 size LED bulbs to replace the incandescents in the cabin wall fixtures. Don't know if my fixtures are stock or replacements. With shipping, the bulbs are $20 each (yeow!!) but I like the minimal battery draw.
