1. A headlight adjustment system comprising:
a headlight positioned in a vehicle;
a measuring assembly attached to the headlight;
an adjust system connected to the measuring assembly; and
a moving mechanism connected to the adjust system and the headlight, the moving mechanism adapted to:
physically alter a configuration of the headlight in response to an optical beam of the measuring assembly extending past a liquid opaque articulating reference member to an optical receptor connected to the adjust system, which extension of the optical beam past the liquid opaque articulating reference member indicates the headlight is misaligned; and
deactivate the adjust system in response to a signal indicating that the optical beam is blocked by the liquid opaque articulating reference member, which blockage of the optical beam indicates the headlight is aligned.
