Ride your motorcycle meticulously, specially when crossing train tracks, hilly roads, or any other surface that could jiggle your headlight out of alignment. Return the motorcycle to the point exactly where you adjusted the headlight, spot the front wheel on the mark created by the masking tape, and test the light when far more. You’re OK to go if the light is nevertheless straight in the center. If the light has somewhat moved, refocus the beam, test it when far more, and repeat if needed. If the light has shifted noticeably, you may have an adjuster that has to be fixed since it is malfunctioning or broken. However, if the lights are dimmed, and you want to restore their brightness, you can buy a headlight restoration kit.
