This bill amends Illinois' Responsible Outdoor Lighting Control Act to impose stricter standards on new and replacement outdoor lighting purchased with State funds or installed on Department of Natural Resources property. It requires full shielding, low correlated color temperature (down to 2200K after 2032), limits on light trespass and upward light emission, minimization of lighting intensity, and preference for reflective roadway markings over electric lighting where safe. Numerous exceptions are provided for safety, security, federal preemption, historic properties, sports events, and holiday lighting.
HB5474 Enrolled LRB104 19241 BDA 32687 b 1 AN ACT concerning safety. 2 Be it enacted by the People of the State of Illinois, 3 represented in the General Assembly: 4 Section 5.

Light should not be emitted 20 at an angle above 60 degrees from the downward vertical 21 direction of nadir. 22 (2) Luminaires must avoid light trespass by not 23 exceeding an illuminance of one lux as measured at ground HB5474 Enrolled - 2 - LRB104 19241 BDA 32687 b 1 level both horizontally and vertically at the property 2 boundary. 3 (3) Luminaires purchased or installed on or before 4 June 30, 2032 must have a correlated color temperature 5 less than or equal to 2,700 Kelvin. All new luminaires 6 purchased or installed after June 30, 2032 must have a 7 correlated color temperature less than or equal to 2,200 8 Kelvin. In residential areas, dark sky locations, or 9 environmentally sensitive areas, such as State parks and 10 outdoor recreation facilities, correlated color 11 temperature should be no more than 2,200 Kelvin. 12 (4) Outdoor lighting must be minimized to no more than 13 25% above ANSI/IES standards or United States Department 14 of Transportation recommendations. 15 (5) Facade lighting must be minimized to no more than 16 25% above ANSI/IES standards, must project downward, and 17 must not violate the light trespass limits in paragraph 18 (2). 19 (6) When the installation or replacement of roadway 20 lighting is planned, the appropriate authority must 21 determine whether reflective roadway markings or 22 reflective signage is appropriate and safe for the 23 situation in lieu of outdoor lighting. Reflectorized 24 roadway markings, lines, warning signs, informational 25 signs or other passive means must be used for roadway 26 lighting, except at intersections of 2 or more streets or HB5474 Enrolled - 3 - LRB104 19241 BDA 32687 b 1 highways, unless it is determined that adequate safety 2 cannot be achieved by reflective means. 3 (7) No artificial lighting above one lux, as measured 4 at ground level both horizontally and vertically, may 5 trespass onto land or waterways designated or managed as 6 habitat, reserve, natural area, open space, or wilderness. 7 (Source: P.A. 103-1007, eff. 1-1-25 .) 8 (415 ILCS 200/20) 9 Sec. 20. Exceptions.

Lamps emitting greater 6 than 2,700 Kelvin under this paragraph must be positioned, 7 angled, or shielded to prevent direct glare and light 8 trespass onto neighboring property or properties, and the 9 positioning, angling, or shielding must limit upward light 10 emission to only the amount necessary to light the 11 sporting or grounds activity; 12 (8) flagpoles installed after the effective date of 13 this Act are lit by means of a downward-facing lamp and 14 using a lamp of 2,700 Kelvin or lower; 15 (9) flagpoles installed on or before the effective 16 date of this Act are upward-lit by partially shielded or 17 unshielded luminaires using a lamp of 2,200 Kelvin or 18 lower to minimize the impact of glare, light trespass, and 19 sky glow and are converted to conform to requirements upon 20 retrofitting; 21 (10) the luminaires luminaries are existing decorative 22 and ornamental lighting that serve historical purposes, 23 but replacement luminaires luminaries for the existing 24 decorative and ornamental lighting must meet the standards 25 of this Act to the extent possible while maintaining 26 historical fidelity ; or HB5474 Enrolled - 5 - LRB104 19241 BDA 32687 b 1 (11) the luminaires luminaries are temporary seasonal 2 holiday lighting lasting no longer than 45 days 3 surrounding the holiday season ; or . 4 (12) it is necessary to use uplighting for statuary 5 lighting and historical fa�ade lighting. In cases where 6 uplighting is the only viable solution for these items, 7 the lighting should have a color corrected temperature of 8 no more than 2,700 degrees Kelvin, must be minimized to no 9 more than 25% above ANSI/IES standards, must not violate 10 the light trespass limits in paragraph (2) of Section 15, 11 and must be extinguished every night no later than 12:00 12 a.m. After January 1, 2027, any new placement or 13 replacement of uplighting of State historic statuary and 14 State historical fa�ade lighting shall be approved by the 15 State Historic Preservation Office. 16 (Source: P.A. 103-1007, eff. 1-1-25 .) 17 (415 ILCS 200/25) 18 Sec. 25.

The governor or the President signs the bill, vetoes it, or lets it become law without a signature. A legislature can also override a veto and enact the bill anyway.
