FIRE??????
Bad enough to burn wires too?
OK .... I am having to paint mental photographs here --- but I don't understand your question about lack of a headlight adjustment affecting other vehicle parts .... really?
I guess .......................... if they aren't adjusted correctly that you can run into mooses, deer, pedestrians, trees and all those things can affect the other vehicle parts-n-pieces ........ if you have sufficient velocity at that time.
Other than that --- I have nothing else to add at the moment until some clarity of intent is posted.
Fire? Really? Got any pictures or videos from The 6 O'clock News?
