I have a 99 Sport. The problem is that when I turn on the headlights, the brights turn on and when I try toggling between high and low beam, the beam changes somewhat but not necessarily from a high to a low beam. Also the little blue high beam light is also constantly on whenever I have the headlights on. Since the highbeams are always on, the foglights are not able to be turned on. Part of my problem is that when I replaced the bulbs after buying the truck used, I bought the silverstars instead of what the previous owner had. I am thinking that I did not put the correct bulb number in. I should have 9007's in the outboard light and 9004's in the inboard correct? I could understand how this may mess up the beam that is coming out of the lights when I switch from high to low beam but I don't understand why the high beam light in the dash never turns off. I have also replaced the toggle on the steering column and that did not change anything. Sorry for the long post, does anyone have any ideas?
