October 1, 2023 – Assessment of Headlamp Aim for New Vehicles – NHTSA report.
March 22, 2023 – Performance investigation of different headlights used in vehicles under foggy conditions – LED headlights are worse for driver detection times in fog.
July 23, 2022 – Why are LED Headlights so Glaring? – In this two-part video, Dr. Peter Veto explains the technical details of why LED headlights are so dangerous. LEDs are a small source, thus emitting more glare and LED headlights emit more high-energy blue wavelength.
December 15, 2021 – The Phantom Wiggle – Dr. Peter Veto recently identified The Phantom Wiggle, which shows LED visible radiation appearing to move in space. This effect has not yet been studied, but the effect is related to the fact that LEDs have flicker and the brain is unable to properly locate the source in space. This effect may have serious consequences our ability to judge distance when a vehicle is using LED radiation devices.
June 23, 2021 – Adaptive Driving Beam and Glare – Dr. Peter Veto discusses the fallacy of ADB headlights.
March, 2021 – Pedestrian Fatalities by State: Preliminary 2020 data – – This report shows that pedestrian fatalities increased by 21% from 2019 to 2020.
April, 2019 – Comparison of European and U.S. Specification Automotive Headlamp Performance – AAA report discusses Adaptive Driving Beam.
January 28, 2018 – Driving in the Dark: Designing Autonomous Vehicles for Reducing Light Pollution – This engineering ethics article discusses how damaging light pollution is to our ecosystem and how we can design autonomous vehicles to have minimal external lights.
October, 2017 – Development of a System to Study the Impact of Headlight Glare in a Driving Simulator – This article discusses the design of a simulator to study LED headlight glare.
September, 2008 – Nighttime Glare and Driving Performance: Research Findings – NHTSA Report
February, 2004 – LightAware Report – This report shows crash and fatality statistics showing a positive relationship between the introduction of LED headlights and vehicle crashes and pedestrian deaths.
2004 – NHTSA ASTEX Case – This report demonstrates that at one time, NHTSA actually did investigate and take action when headlights did not comply with FMVSS-108.
January, 2003 – Why HID headlights bother older drivers – HID headlights cause problems for older drivers due to the intensity.
November, 1989 – The Measurement of Dark Adaptation Level in the Presence of Glare – Study on the impacts of light on rods and cones from headlights.
Examples
The video below shows the blinding glare from LED headlights.
The video below shows an LED radiation device being used at an intersection in India. with NHTSA failing to enforce its own regulations, this device could theoretically be placed into a vehicle and used as a headlight.
