I recently upgraded my bulbs to LED and noticed this. I first thought it was a bulb issue, so i swapped bulb sides and it still is the same. The headlights turn on, but there is very little light on the drivers side. I was in a fender bender a few years ago where there was some damage done to the front drivers side. I dont think the headlight needed replacing but wondering if there might be some kind of internal damage thats causing it to appear like its not working
