The housing with the 4- fiber optic cables going off to the right in the picture is the Seelite cable assembly. Light comes out the other end of the fo cables which are attached to the back side of the dash. They provide backlighting for the wiper switch and the headlight switch.
The screwdriver is pointing to the Seelite cable assembly lamp socket. A #181 bulb plugs into this socket. The socket then plugs into the Seelite cable assembly. This is a 3 candlepower bulb. It must get pretty hot looking at the charring on the housing.
Here is a drawing from the 1969 Chassis Service Manual showing more detail. There may be another Seelite assembly on the right side of the steering column if the car has accessory switches.
