97 Impreza Headlight Turn Off Unexpectedly


Recommended Posts

Lights will go out for a few seconds then both will come right back on. Kind of alarming driving at night. Can't find a common theme when it randomly occurs. Could be just driving down the road, no bumps or braking and poof, they are out. Five seconds later they are back. Then may not see it happen again for a week.

 

Any thoughts where to start?

Do you have a volt meter? Connect it to a 12v+ FUSED source like the cig lighter outlet and watch your voltage when it happens. It might actually be something like the A/C kicking on and the engine is getting slowed down for a second until the idle speed kicks up to compensate for the added load. My 95' kicks the compressor on/off when the heater is on too, which seems to deal with preventing fogging of the windows (or something is wrong as this feature seems kinda new for a 95') but on rare occasions when the heat is on, head lights on, seat heater on, and stereo going full-tilt and coming to a stop, it takes a second for engine to adjust and lights will dim for a split second. That's running a 130 amp Tribecca alternator mind you.

 

 

If your lights are going completely dark, it could be the dash switch, head light relay x 2, bad ground, bad filament in the bulbs (I've seen then die, hit a bump and come back after making contact again, then 30 minutes dead again so don't rule out the obvious).
