Dear Supporters,

In September, 2025, the industry publication Driving Vision News hosted a vehicle lighting workshop.  DVN also held a forum about headlamp glare and a report was published on September 23, 2025.  This report is worth your time to read.

Some of the key ideas in the report are the references to luminance and size of the light source.  These are key factors that, until just recently, almost nobody had been talking about.  These metrics are unregulated, and yet are two of the primary causes of the debilitating glare.  The other causes of glare are blue wavelength light and headlamp mounting height.  It is a significant step forward that the industry is finally starting to understand the issues we have been experiencing in the real world.

A major culprit for the bad LED headlights we encounter on the roads today are due to criteria set by the Insurance Institute for Highway Safety (IIHS).  Automakers attempt to meet these guidelines to earn good ratings from IIHS, but the guidelines do a bad job of protecting us from blinding glare.  Talk to your insurance agent about this and ask if you can get a response from your insurance company as to why the industry group IIHS doesn't update it's standards to address blinding LED headlight glare.
