Point detail

Four seconds after ignition of a headlamp which has not been operated for 30 minutes or more, at least 37,500 cd must be reached at point HV of a driving beam and 3,750 cd at point 2 (0.86D-V) of a passing beam for headlamps incorporating driving beam and passing beam functions, or 3,750 cd at point 2(0.86D-V) for headlamps having only a passing beam function. The power supply shall be sufficient to secure the quick rise of the high current pulse.
