SB1477

Modifies provisions relating to accessories of motor vehicles

Chamber Passed·4/16/26

Missouri SB1477 modifies motorcycle headlamp regulations, allowing modulation and additional auxiliary lighting.

Missouri SB1477 revises the rules for motorcycle headlamps, allowing modulation of the upper or lower beam under specific conditions. It mandates that the modulation rate be between 240 and 440 cycles per minute and that the headlamp operates at maximum power for 50-70% of the time. The bill also specifies light intensity thresholds and requires both beams to remain operable in case of a modulation failure.
