Audio/Visual Electronics - headlights just go out...94 civic ex

headlights will just go out from time to time and then come back by themselves or after switching the highs on or switching the headlights on and off...

i hear there is a device that can be replaced...

suggestions??

First , visually inspect the headlite bulbs and lite bulb sockets for any corrision . Inspect all ground wires for headlites. CHeck the combination light switch / headlight lite switch for loose connection under steering column unplug and reconnect it. Purchase a hayes / chilton repair manual for your 94 civic.
