In a 1981 Chevy Caprice Classic, the light switch is typically located on the dashboard to the left of the steering wheel. It is usually a pull-type knob that controls the headlights and interior lights. To activate the headlights, pull the knob out, and to turn on the interior lights, you may need to twist or push it, depending on the specific configuration.
