Headlight/Electrical Problem, Help Please

[Sled14]

On my Cougar, one side of the front lights (high beam, low beam, turn signal) is noticeably brighter than the other side. The passengar side lights are not as bright than the driver side. I've replaced my headlight switch but that didnt make a difference.



Also, the turn signal indicators are usually very dimly lit, and sometimes the drivers side turn signal indicator gets a little brighter, then when I turn the signal on just so it flashes once, it will go back to being just dimly lit.



If anyone could offer advice on how to fix this problem, I would really appreciate it.
