Villa votes in favor of SB3037 to update outdoor lighting regulation, address light pollution

Sen. Karina Villa (D-25th) supported SB3037, casting a Yes vote during the 104th General Assembly on May 31, 2026, on the measure aimed at renaming and enhancing outdoor lighting standards to curb light pollution. The Illinois Senate approved the bill with a 57-0 vote.

According to the official bill language, the act will be known as the "DARK SKY ACT."

The following analysis is a summary of the bill text and incorporates interpretation to clarify its main provisions.

Essentially, the legislation renames the Responsible Outdoor Lighting Control Act as the Dark Sky Act and, as soon as it becomes law, imposes tougher statewide standards on outdoor lighting to limit light pollution and protect vulnerable ecosystems. Beginning Dec. 1, 2026, most new or renovated exterior lights purchased with state funding or placed on state property must comply with requirements for brightness, glare, unwanted light spill, color temperature, proper shielding, and limitation of unnecessary lighting at night. The law establishes heightened restrictions near undeveloped natural areas, institutes sports lighting rules, and ensures federal, state or local authorities may enforce stricter standards. Specific exceptions are defined for security, urgent needs, safety purposes, historic lights, and some temporary or seasonal installations. The Department of Central Management Services is tasked with deciding agency exemption requests within 30 days.

SB3037’s official action was 'House Floor Amendment No. 1 Senate Concurs'.

Villa, a Democrat, has served the 25th Senate District since 2021, succeeding Jim Oberweis in the Illinois State Senate.

The legislative process in Illinois involves multiple stages, beginning with bill introduction, then proceeding through committee consideration, floor discussion, and votes in both legislative chambers before submission to the governor for signing or veto. Convening every two years, the General Assembly frequently sees thousands of bills filed, though only a limited portion advance through all steps to become law.
