Restoration pack says:

In the other section that lays out the specs in more detail:
TAIL AND STOP LIGHTS
Make and type..........Guide, combination
Number and location: Two-unit bodies.........One, attached to rear end of frame left side member
Canopy Expresses and Suburban Carryall.......One, centered on tail gate (linkage automatically adjusts light for tail gate position)
Panels......One, on left rear door.
RPO 249: Panels, Canopy Expresses, and Suburban Carryall......Two, extra combination tail and stop lights, one at rear of each body side panel.
So, there you go! In GM's own words. For the 1952 models.
