Kentucky requires lamp on the front emitting a white light visible from at least 500 feet to the front, required between one-half hour after sunset and one-half hour before sunrise. For the rear, red reflector on the rear of a type approved by the kentucky transportation cabinet, visible from all distances from 50 feet to 300 feet to the rear when directly in front of lawful lower-beam headlamps. a red rear lamp meeting the reflector's distance test may be used in addition to (but not in place of) the reflector. The rule applies whenever it is dark. See 601 KAR 14:020 (Bicycle equipment and operation).
The cheapest way to stay legal in Kentucky is a USB-rechargeable front white light and a rear red light or reflector that meets the spec above. A $30 light set covers it.
Be seen, stay legal

Most state codes require a white front light visible from 500 feet plus a rear reflector or red light. See lights that hit the spec and last a full commute.
