hey guys i have a question again about headlight aiming i've been trying to adjust the horizontal movement of the light but doesn't seem to move. the up and down vertical moves. i noticed by pointing at the wall that my left headlight seems to point inward. i tried many times to turn the **** to adjust it but doesn't seem to move. i tried moving it all the way to tleft and all the way to right still at the same place i tried centering it too. did this with the headlight on so i can see the movements.. is there any other way to adjust the horizontal movement of the headlight.besides the ****. thanks guys

PS how do i replace the parkling light bulb i had trouble taking it out. on a sc 300
