ABSTRACT:
A method and device for indicating alignment of a pair of headlights. A pair of elongated members are removably mounted by suction cups to the forward-looking faces of a pair of headlights. Each elongated member includes a sight-line scope which is used to visually observe a lateral aim mark on the elongated member mounted to the opposite headlight. The vertical aim of each headlight is adjusted until the bubble levels on the members are properly centered. The lateral aim of each headlight is adjusted until the lateral aim mark on one elongated member is properly centered relative to the sight-line scope provided on the opposite elongated member.
