AD Suburban Bullet Taillight Configuration
These were the same as '39 Chevy passenger car tail lamps.
There was also a service bulletin issued in '48 to use a bullet light over the doors as a tail light if driving with the doors open.
Looking through a 1950 Chevrolet Truck Data Book and it had the accessory
"bullet" lamps listed as dual-filament stop/tail lamps.
The '39 Chevy passenger car tail lamps were most likely single filament?
We wonder if they were dual filament for all Advance Design years?
(If you know drop us a line!)
