Decoder Ring | The Glaring Problem with Headlights

Something seems to have happened to car headlights. In the last few years, many people have become convinced that they are much brighter than they used to be—and it’s driving them to the point of rage. Headlight glare is now Americans’ number one complaint on the road. The story of how and why we got here is illuminating and confounding. It’s what happens when an incredible technological breakthrough meets market forces, regulatory failure, and human foibles.

So if you feel like everyone’s driving around with their high beams on all the time, it’s not your imagination. What once seemed like an obscure technical concern has gone mainstream. But can the movement to reduce glare actually do something about the problem?

In this episode, you’ll hear from Nate Rogers, who wrote about the “headlight brightness wars” for The Ringer; Daniel Stern, automotive lighting expert and editor of Driving Vision News; and Paul Gatto, moderator of r/fuckyourheadlights.
