GMONIZ,
I could not find the dual-tail-light/bullets for panel-body trucks article either under Suburban, Panel, or electrical sections (47-55 Tech Articles). I think I remember seeing one in the past.
JC has an article about the single add-on tail light for above the panel truck rear doors (
1948 Canadian panel bodies ) and an article about dual tail lights on other truck bodies, stating this about panel bodies:
"Neither the single factory taillight on the double door or the center unit on the tail gate were in a good position to be matched with a second live assembly. GM solved this by offering a turn signal kit containing two matched taillights. These were dealer installed beside the vehicle belt line near the doors and above the edge of the tailgate. These small bullet shaped lights were actually from a 1939 Chevrolet passenger car. It appears GM dusted off the ten year old car taillight tooling and kept expenses on this option to a minimum. The letters "DURAY" are stamped in the top of the painted housing. The chrome bezel retains a 2 5/8 inch diameter red glass lens. Due to a small water drain hole, there is a right and left on these turn signal lights."
