70 Swinger Ashtray

according to the factory sales brochure the "light group" package includes (and I quote):
fender mounted turn signals (N/A Swinger 340)
Head-lamp-on reminder buzzer
Glove box light
light: ashtray
Map and courtesy light
Trunk light
Ignition with time delay

to explain:
the Map and courtesy light was under the dash way over on the passenger side - you wouldn't want the driver to be reading a map while driving in the dark! The courtesy part was that the same light would come on when you opened the passenger door to make it easier for them to see getting in. The switch for the map light was to the left of the steering column so that the driver had control of turning it on or off while driving. If you want pictures, just ask.

The ignition time delay was a little light behind the ignition key bezel. It came one when you opened the drivers door so you could more easily get the key in the ignition. The delay part is that it would shut off after so many seconds so it wouldn't reflect on the windshield while driving in the dark

Head lamp on reminder buzzer would come on if you shut off the ignition with the headlight turned on.

The one that really confuses me is that you couldn't get fender turn indicators on a 340 car. All I can figure is that you wouldn't have been able to easily see the right side one over or around the scoop on that side.
