HRS §291C-200
When mopeds must have lights on
Mopeds on a road must turn on their headlight and tail light from half an hour after sunset until half an hour before sunrise, and whenever it is too dark to see people or vehicles 200 feet ahead. Inside a tunnel, mopeds must always have both lights on.
The statute, as written — Use of lamps on mopeds
Every moped moving upon a highway from thirty minutes after sunset until thirty minutes before sunrise and at any other time when there is insufficient ambient light to render clearly discernible persons and vehicles on the highway at a distance of two hundred feet (60.9 meters) ahead shall display a lighted head lamp and tail lamp; provided that every moped upon a highway within a tunnel shall at all times display a lighted head lamp and tail lamp.
