You may use any noise device except sirens or whistles (373.05).

Bicycles are required to have reflectors or lights:

• From sunset to sunrise (337.02a1).
• When fog, snow, smoke, or other unfavorable atmospheric conditions make it difficult to see objects 1,000 feet ahead (337.02a2).
• Whenever precipitation requires motorists to use their windshield wipers (337.02a3). Under these conditions, however, law enforcement may not stop bicyclists or issue a ticket (337.02d).

Yes, bicycles must have a headlight (373.06a1). A white reflector does not substitute for a headlight.

Yes, either reflectors or lights may be used (373.06a2). If you’re using a rear light, you’re not required to have a rear reflector in addition (373.06a3).

No, you do not need reflectors if you’re using front and rear lights that work adequately (373.06).

An adequately working front headlight is one that is visible of at least 500 feet in front, and 300 feet to the sides of the bicycle (373.06a1). The law does not specify if headlights must be either flashing or steady. For the rear, flashing or steady lights that can be seen from a distance of 500 feet are considered adequate (373.06a3).

No, this is illegal. Only white lights can be used on the front of your bike, and red lights for the rear (373.06b).

There is no law requiring reflectors or lights between sunrise to sunset, and when visibility is adequate.
