The 20585 has diagonal hinges on the bulb rings. The 20595 has the hinge on the Red light horizontal. This light looks like it had an updated 20585 mechanism installed in it with the new can motor.

Horizontally mounted 20585 Gyralite
The light came from a SP U33C. The mechanism came from a D&H light.
The light was originally mounted vertically as is evidenced by the
rust marks to the right of each lens ...telltale signs of former visors.
