My headlights aren't working right *need help*

I bought a 97 prelude recently and it looked fine and everything but one day when i was driving it one of the headlights didnt work...so i opened it and checked it, it doesnt seem broken or anything but i still bought a brand new pair of H1 headlights for 31 bucks and i installed them and they work fine for 3 days than the light broke again on the same side. Well i took the working bulb from the old pair and installed that in...it worked for a few days than broke again this time on the side that i had no problems with...so is this an electrical problem? wiring problem or the bulbs crapping out on me?? i need help pleasse someone

Check the bulbs to see if they are bad. Could be a wire, relay etc. If the bulbs are going that fast then the voltage may be high.
