okay my left head light works fine but my right head light is dim and my fog lights dont work. When i have my right turn single on both my turn single and right head light flash. Also when my right turn single is on the little light in my fog light button flashes. I drive a 1999 ranger 4x4.

 

Check yoru grounds - sounds like somethign is going off and discharging something perhaps.. a cable might have worn through and is touchign the frame somewhere near the headlights area.


with your headlights on, try twisting and moving around the cables to see if anythign changes in there.. might have some corrosion going on - the good news is that the lights still work, shows its not a bulb issue.
