I don't know if it was used on all GMCs or not, but on my 76 PB the lights
for part of the dash is provided by a single bulb that is piped via fiber
optics to several points. The light is installed behind the dash.

Franz,

GMC maintenance manual, page 12-25:

"Lighting for windshield wiper control, main light switch and washer switch
is transmitted through a fiber optic ribbon from a main source bulb located
on the L.H side of the lower instrument panel cover. ......"

Mine doesn't light up, so I'll know more about it soon!

Andy,

The high beam indicator has its own bulb, it gets power ( light green wire
from the dimmer switch ) and ground ( black wire from dash panel ground )
through the speedometer printed circuit and connector.
