yes i did check all my cables adn connections and everything good. The story with is going on for awhile when i had my old battery it happend only when i used my horns at night then my battery died i got new one adn everything was still the sane (dimming at night only) but a couple weeks ago i nocided it dimms when i roll my windows up and even at day time i can see light on my dash dimming a lit bit without headligths on. So i start suspecting my alternator and im probly going to get the one that biju reccomended.
