Lisa asked: Can you wear a helmet or hat with a light on it instead of a light on your bicycle?
The statute says the bicycle must be so equipped. The bicycle and rider can have additional lighting.
s. 316.2065 – Bicycle Regulations
(7) Every bicycle in use between sunset and sunrise shall be equipped with a lamp on the front exhibiting a white light visible from a distance of at least 500 feet to the front and a lamp and reflector on the rear each exhibiting a red light visible from a distance of 600 feet to the rear. A bicycle or its rider may be equipped with lights or reflectors in addition to those required by this section.
