Thank you for the reply.
Lots of interesting lights, but not the one I needed.
It is a close to floor courtesy light, there are 2 in the back part of the cabin of the Seneca with a total dimension of 1' x 4.25" of the dark tarnished grey frame and the actual visible light lens 2 5/8 x 5/8, inset in that frame.
