So, my headlights are uber dim. On top of that when I hit the high beams they turn on all 4 lights, but start surging/blinking on for a second off for a second (repeat). When I take the high beams off it is just 2 dim headlights that don't shine any further than 10ft. So, I bought some LED headlights that are supposed to be 3-4x brighter and they are also dim. I'm guessing I'm not pulling enough power. I don't know how to fix that problem. New wiring harness? New alternator? All or none of the above?
