This circuit automatically switches on the headlights of a ear after the engine is
started. In countries like Sweden and Canada, ear drivers must have their
day-running lights on, even in broad daylight. Aeeordingly, ears manufactured
or imported into these countries often have an automatie lights-on control
which, although it can not be disabled, leaves the normal light switch in
function. A similar circuit with automatie switch-on, switch-off and reduced light
intensity is described here.
