March 22, 2023Performance investigation of different headlights used in vehicles under foggy conditions – LED headlights are worse for driver detection times in fog.

July 23, 2022Why 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, 2021The Phantom WiggleDr. 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.

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.
