Ohio Rev. Code § 1533.161: Prohibiting jacklighting.

No person shall throw or cast the rays of a spotlight or other artificial light from any vehicle into any field, woodland, or forest while having in his possession a hunting device, or throw or cast the rays of a spotlight or other artificial light from any vehicle into any field, woodland, or forest for the purpose of locating a wild animal.

This section does not apply to law enforcement officers, wildlife officers, military personnel, and officers or employees of the department of natural resources while in the performance of their duties, or to any landowner or lessee having a reason to use a light while engaged in surveillance or protection of his property.

An officer whose duty it is to enforce this chapter and Chapter 1531. of the Revised Code and division rules may arrest a person whom he has reasonable grounds to believe is violating this section, search the vehicle for firearms or other hunting implements in the possession or under the control of that person, and seize the same.
