Here's how they work as far as I know: the headlights are neutral, can stay
up or down and are not preloaded. Now, when the engine starts and there is
vacuum, to stay down the relay(s) have vacuum going to them, they open and a
separate vacuum circuit sucks the actuator down (these two circuits might
have a common portion, I just can't remember, like they might have the same
source but regardless they are essentially separate). If vacuum on that
circuit is lost, the relay(s) are spring loaded and without vacuum they go
to the open position. The upshot is, of course, if you want the lights to
stay down when the engine is running you can do it a couple of ways. You
could get vacuum to that circuit and have them work correctly or you could
block off the vacuum going to the relay and operate the lights manually (but
frankly with no "close" vacuum they might work their way open while driving
-- I never tried it). But the system is fairly easy and straightforward to
fix. Kim
