The rule of thumb that keeps you legal in nearly every state: at night, a white light in front and a red light (plus a red reflector) behind. State codes word it differently, but the core is the same: a front lamp visible from 300 to 500 feet (90 to 150 m) and a red rear reflector or lamp. Federal rules add the reflectors that come on every new bike.

What the law usually requires at night
Most state codes follow the same pattern:
- When: “at nighttime” or “during darkness”, which states define differently: Florida says sunset to sunrise, New York from half an hour after sunset to half an hour before sunrise.
- Front: a lamp emitting white light, visible from a set distance ahead.
- Rear: a red reflector, and in some states a red lamp too.
- Brakes: while not a lighting rule, the same section often requires a brake that can make the wheel skid on dry, level pavement.
Bike light laws in four large states
| State | Front light | Rear | Other requirements |
|---|---|---|---|
| California (Veh. Code § 21201) | White light visible 300 ft (91 m) ahead and to the sides; may be worn by the rider | Red reflector, or solid or flashing red light with built-in reflector, visible 500 ft (152 m) | White or yellow pedal (or shoe or ankle) reflectors visible 200 ft (61 m); side reflectors or reflective tires; e-bikes need the rear reflector or light at all hours |
| Florida (Stat. § 316.2065) | White lamp visible 500 ft (152 m), sunset to sunrise | Red lamp and red reflector, visible 600 ft (183 m) | Extra lights and reflectors allowed |
| New York (VTL § 1236) | White lamp visible 500 ft (152 m), from half an hour after sunset to half an hour before sunrise | Red or amber light visible 300 ft (91 m) | One light visible 200 ft (61 m) from each side; bell or horn audible at 100 ft (30 m); new bikes need reflective tires or spoke reflectors |
| Texas (Transp. Code § 551.104) | White lamp visible 500 ft (152 m), at nighttime | Red reflector visible from 50 to 300 ft (15 to 91 m), or a red lamp visible 500 ft (152 m) | Brake able to skid a wheel |
For other states, search your vehicle code for “bicycle” plus “lamp” or “reflector”; the section is usually next to the other bicycle rules. If your state is not listed here, the safe setup is the strictest one above: a bright white front light, a red rear light and a red rear reflector.
Reflectors on new bikes: the CPSC rule
Federal law does not tell you how to ride, but it does say what a new bicycle must have when it is sold. The Consumer Product Safety Commission’s bicycle standard, 16 CFR 1512.16, requires:
| Where | Reflector | Color |
|---|---|---|
| Front | One forward-facing reflector | Essentially colorless (clear) |
| Rear | One rear-facing reflector, mounted behind the seat post, its top at least 3 in (76 mm) below the saddle | Red |
| Pedals | Reflectors on the front and back of each pedal | Clear or amber |
| Wheels (sides) | Spoke reflectors within 3 in (76 mm) of the rim, or reflective tire sidewalls, or (only on bikes without rim brakes) reflective rims | Front wheel clear or amber; rear wheel clear or red |
Sidewalk bicycles (small kids’ bikes) are exempt. These reflectors are what state laws like California’s side and pedal rules build on, so if you remove them, you may be out of compliance at night even with good lights. Clipless pedals rarely have reflectors; in a state that requires pedal reflectors, California lets you put them on your shoes or ankles instead.
Choosing lights that meet the law
- Brightness: the laws set visibility distances, not lumens. Pick a light whose maker states it is visible from at least 500 feet, and go brighter if you also need to see the road on unlit routes.
- Flashing modes: California explicitly allows a flashing red rear light. For the front, a steady beam is the safer choice in states whose code just says “a lamp”.
- Daytime: most state laws only require lights at night, but a rear light in the daytime makes you easier to see. California’s 2026 change already makes the rear reflector or light a full-time rule for e-bikes.
- Reflective gear: a vest or ankle bands is not a substitute for required lights, but it helps drivers judge that you are a person on a bike.
For the rest of the rules, see bike helmet laws, e-bike laws and riding on the road and safe passing.
Frequently asked questions
Is it illegal to ride a bike at night without lights?
In practice, yes. State vehicle codes require a white front light at night and a red rear reflector or light. In Florida, Texas and New York the front light must be visible from at least 500 feet; in California, from 300 feet.
Do I need a rear light or is a reflector enough?
It depends on the state. California and Texas accept a red rear reflector or a red light. Florida requires both a red rear light and a reflector, and New York requires a red or amber rear light visible from 300 feet.
Can I use a flashing bike light?
California explicitly allows a solid or flashing red rear light with a built-in reflector. Other states are less clear, so a steady front light plus a flashing rear light is the safest setup. Check your state code for the wording.
What reflectors does a new bike need?
Under federal CPSC rules (16 CFR 1512.16), a new bike is sold with a clear front reflector, a red rear reflector, reflectors on both pedals and reflectors on each wheel or reflective tire sidewalls.
Can a helmet light replace a handlebar light?
In California, yes: a white light attached to the rider and visible from 300 feet counts. The Florida, New York and Texas codes say the bicycle must be equipped with the lamp, so keep one on the bike there.
