To meet STVZO standards, bike lights must have a well-defined horizontal cutoff line to prevent glare, sufficient illumination range, and an optimized intensity distribution. Key optical design elements include:
Lens Design: Focuses the light to create a sharp horizontal cutoff.
Reflector Geometry: Directs the light through the lens to shape the beam pattern.
LED Placement: Ensures precise positioning of LEDs to achieve the desired light distribution.
