If you have ever met an oncoming vehicle at night and wondered whether its headlights belonged on an airport runway, the federal government has an announcement you will appreciate. The National Highway Traffic Safety Administration says it plans to modernize America’s vehicle lighting standards, with headlight glare among the issues getting attention.
In an Oct. 6 announcement, NHTSA outlined a review of Federal Motor Vehicle Safety Standard No. 108, the federal regulation covering vehicle lamps, reflective devices and associated equipment. The agency says its goal is to improve safety while updating requirements that can limit the use of newer lighting technologies.
For drivers, the central challenge is straightforward: Headlights need to illuminate the road well enough for the person behind the wheel without interfering with another motorist’s ability to see. NHTSA plans to examine how modern headlighting technology contributes to glare and determine what regulatory changes are appropriate.
The announcement begins a process for developing revised standards. It does not establish a new headlight brightness limit, order owners to replace their headlights or provide a date when revised requirements would take effect. The details will depend on the rulemaking that follows.
NHTSA Administrator Jonathan Morrison said existing standards restrict automakers’ ability to introduce some newer lighting technologies that could improve safety. He said bringing technical experts and other interested parties together would help the agency modernize its requirements and address potential causes of glare.
The review will cover several areas beyond brightness. NHTSA intends to evaluate headlamp height and aim, including how those factors affect driver visibility. That puts attention on where headlights are mounted and where their beams point, along with the technology producing the light.
The agency also plans to improve rules governing LEDs, dusk sensors, automatic high beams and replaceable light sources. These subjects involve both the lights themselves and systems that control when they operate. NHTSA’s announcement identifies them as priorities but does not spell out the requirements manufacturers would eventually have to meet.
Another part of the effort concerns testing and materials. NHTSA says it wants to streamline test procedures for plastic optics and replaceable lenses. It also intends to bring U.S. lighting regulations into closer alignment with international safety standards. However, the announcement does not identify particular overseas requirements it plans to adopt.
There is some important history here. In February 2022, NHTSA issued a final rule allowing adaptive driving beam headlights on new vehicles. According to the agency, those systems adjust the beam to direct less light toward occupied areas of the road while providing more illumination elsewhere. The technology is intended to improve nighttime visibility without increasing glare for other drivers. That earlier change means federal lighting rules have been updated before; the current announcement sets out a broader modernization effort.
To develop the changes, NHTSA will use negotiated rulemaking, a process it says it has not used in more than 25 years. Transportation Secretary Sean P. Duffy will appoint up to 18 participants representing lighting manufacturers, motor vehicle equipment associations, safety organizations, research institutions and engineering associations. The agency says the collaborative approach is intended to accelerate the work.
NHTSA is accepting public comments on the effort’s scope and the balance of committee membership, along with nominations for committee seats. Comments and membership applications are due Nov. 9, 2026, under docket NHTSA-2026-1981.
For motorists, the promise is better lighting performance with closer attention to glare. Whether the eventual regulations deliver that balance will depend on the technical decisions ahead. For now, NHTSA has put the issue on its rulemaking agenda, with both seeing the road and sharing it safely at the center of the discussion.
