Head Light Vacuum Leak
When my head lights are on ('76 L48), I'm getting a rough idle which I suppose is a leak somewhere in the light's vacuum system. Anyone have an idea of where to look for this??

If you can't hear the leak us a Process of ellimination. The vaccum is drawn from the rear driverside area of your block. Hoses go to a pulldown switch under your steering column, then to the headlight switch, from there to the headlights. Could be anything. Block each hose until you find the one leaking.
