ok so im driving all normal and stuff and i get to a red light in the turning lane, put my blinker on and realize everytime it flashes, my rpm hand would move, so i thought nothing of it and kept driving. a little on down the road, my hid's start to flicked and my battery light starts to slightly flash, so now im realizing something is wrong. i pull over to check loose wires and everything but nothing. i continue on my way home and my headlights are very dim and the batt. light is randomly flashing on and off. as im getting closer to home, i notice when ever i step on the brakes, my headlight go off and the batt. light comes on and when i take my foot off the light goes off but my headlights stay off. What might the problem be?
