The disclosed safety light (

15

) is designed to provide automatic operation for safety lights placed on rotating assemblies such as wheels, flying disks, and etc. Safety light (

15

) comprises a battery (

20

), acceleration/motion sensor (

22

), photo sensor (

24

), and illumination device (

26

) placed substantially in series with one other. Battery(

20

) provides electromotive power to operate all circuitry. The acceleration/motion sensor(

22

) is designed to conduct current when a specific acceleration or motion is detected. The photo sensor (

24

) conducts current when photo detector(

25

) detects a sufficiently low level of light. When both acceleration sensor(

22

) and photo sensor(

24

) are conducting, current will flow and illuminate illumination device(

26

). Alternatively, a time delay may be added to the acceleration/motion sensor(

22

) to delay shut-off of current to the illumination device(

26

), and a time delay may be added to the photo sensor(

24

) to delay turn-on of current to illumination device(

26

) when light level is suddenly reduced.
