headlights gone dim?

[byebyebaby]

ok i got my 91 hatch running today and i went to hit the lights to test everything and all 4 come on even though the high beam isnt on. on one side the low beam is fine and the high beam is really dim and the other side both bulbs are dim. i just turned them on not more then 2 days ago and they worked fine. could it be a bad ground?bad power?

check all your grounds and i would also check the output on the alternator. -mike

I would check fuses also incase its backfeeding to the highbeams
