Most likely due to a faulty vacuum check valve. It is a little metal disc with one inlet hole and two outlet holes [depending on how you look at it]. It fits in the initial vacuum line from the intake manifold fitting, along with the vacuum filter (the little white plastic disc 'thingy'). If that doesn't block the loss of vacuum from the reservoir tank, and it bleeds down before the headlight actuators lose vacuum, the headlights will raise.
