How does the vacuum operate the headlights in a 1977 corvette?
There is a vacuum line attached to the back of the headlight switch on the dash. When you pull the switch out to turn on the lights this allows vacuum to open the light doors through rubber vacuum lines. When you turn the lights off this cuts the vacuum to the lights and a spring opperates the doors and closes them.

Why might the headlamp switch now fail to raise the headlamps on a 1977 Corvette?
Rarely is due to switch failure, this system uses vaccum to raise the lights, Trace these lines(very easy) from the vaccum pods near the headlights themselves, back to the source, if no leaks are found, make sure you have vaccum at the intake manifold, if you have vaccum at the manifold then test the switch itself. There is a vacuum cutout switch under the steering colum. it looks like an old style door lock knob, if it in the dowm position the lights will stay up.
