Headlights are screwed

[importsaint]

I've had this problem for a while now, where when I turn on my headlightsonly one works at a time. When I had my factory USDM pop-uplights I tried changing the bulb assembly on the side that would not light up during low-beam operation. Didn't work, I know have swapped on the S13 front end, due to a front end collision. Now when I turn on my lights the low beam on the driver's side is on, and the passenger side is off. When I turn on the high beams the driver's side doens't work, and the passenger side projector works. What the F is the problem can someone help... PLEASE!!!
