Right Headlight(s) not getting power

last night i was driving my 94 Si and the right headlight AND corner light would go off and on, turns out just hitting the headlight from the outside (hard) turns it back on, but it seems to happen very often, might be unrelated but ive been having squeeling/screeching problems from my belts ever since i got them all changed about a month ago, but if it was a bad alternater belt you would think both headlights would lose power not just one side...

try checking the harness for the bulb..move it around...my friends civic does that..try wiggling around the wires..thats what fixed my friends problem for awhile
