I noticed just recently that everytime when i apply the brakes either thru the hand brake or foot brake, my headlight goes brighter. When i use the signal light flasher, the headlight intermittently goes from dim to bright just like the blinkers. This happens both in low beam and high beam. Lastly, The light goes from bright to dim when running even without using the brakes or flasher. I'm afraid that i may end up in the dark soon.. It has to be electrical, but where do i start? Has anybody ever have this experience? Thanks!
