The governing body of every municipality may enter into contract in writing with the county park commission of the county in which it is situated to contribute to the cost of lighting any street, public highway, or parkway, wholly or partly within the municipality and under the care and control of the park commission. The contract may provide for furnishing and maintaining the necessary poles, wires, conduits, fixtures and equipment and the lighting, upon such terms and for such period of years as may be agreed upon. The contract shall set forth the kind and character of lighting required, with full specifications and plans, the proportion of the cost of installation and maintenance to be contributed by each party thereto, the period for which the contract is to continue and such other terms and provisions as shall be mutually agreed upon.

This article shall not be construed to limit or impair any powers now conferred upon any municipality or county park commission, but as additional thereto.
