Interior and Upholstery Dome/hatch bulb size?

[Mustang5L5]

What is the size of the dome light in the sunroof cars or the light in the hatch? I can't find it published anywhere? All sources incorrectly state the standard non-sunroof dome light.

I need a new LED and no clue what bulb size this is

561 or 44mm festoon bulb
