Slate Podcasts | Slow Burn Feed | May 21, 2025

Overview: Why Are Headlights So Blinding Now?

This episode investigates the surge in complaints about excessively bright headlights in the US. Host Willa Paskin and journalist Nate Rogers trace the evolution of car headlights—from early oil lamps to modern LEDs—and unpack how technological advances, larger cars, complex regulatory failures, aesthetic trends, and human behavior have led to record levels of glare and frustration on the roads. Through expert interviews and grassroots activism stories, the episode explores not only how we got here, but why solutions remain elusive.

Key Discussion Points & Insights

1. A Personal Headlight Obsession Goes Public (01:34–06:15)

• Nate Rogers’ Experience:
  LA-based journalist Nate Rogers describes a feeling of being “run off the road” (01:56) by blinding headlights. Initially dismissed by friends, he became fixated on the issue, documenting egregious cases and engaging others.
• Cultural Shift:
  By 2024, public memes and rants about too-bright headlights proliferate. The problem turns from a personal annoyance into a mainstream complaint.
  “It seemed like there was kind of a critical mass happening where suddenly it was becoming something that other people were kind of joining in on.” — Nate Rogers (04:17)

2. Historical Context: From Oil Lamps to LEDs (06:15–14:53)

• Enter Daniel Stern:
  Headlamp expert Daniel Stern joins the discussion, emphasizing the distinction between brightness (subjective) and intensity (measurable) (07:48). He confirms the skyrocketing trend in headlight glare complaints:
  “Glare complaints have been increasing all over the world.” — Daniel Stern (08:11)
• Old Problems, New Tech:
  Headlight glare has been an issue since the first electric headlights. The “Goldilocks problem”—too little vs. too much light—has always been present (09:27).
  Early regulations (the “sealed beam” mandate of 1939) standardized headlamp performance and kept glare controlled for decades.
• The LED Revolution:
  LEDs, adopted widely in the late 2000s/early 2010s, are efficient, programmable, and powerful—far surpassing earlier technologies (12:05–14:08).
  • “LEDs, when they were introduced, were a completely different technology that experts in lighting basically consider the most dramatic change in lighting as long as we've been alive.” — Nate Rogers (12:13)
• A Sudden Spike in Problems:
  The advent of LED headlights is pinpointed as the inflection point for unprecedented glare.
  “Headlight glare is definitely and indisputably worse than it used to be.” — Daniel Stern (14:30)

3. Diagnosing the Modern Headlight Glare Crisis (14:55–19:24)

• Key Culprits Identified:
  • Raw Power: LED headlights “at least doubled” in average brightness in the last decade (15:13).
  • Big Cars, Higher Headlights: Large SUVs and trucks put headlights at eye level of other drivers (15:36).
  • Headlight Aim: Maladjusted headlights make the problem worse; LEDs' pixel-like composition throws more light in unintended directions (16:26).
  • Color Temperature: LEDs enable “cool blue” tints desirable for marketing, but blue light is more glaring (17:34).

    “For any given intensity, light with a greater content of blue wavelengths feels more glaring to us than light with less blue in it. …We could snap our fingers and have very effective LED headlamps that were 60% less glaring without changing how well we can see….” — Daniel Stern (18:13)

• Aftermarket Modifications: Regulatory agencies blame DIY and aftermarket LED kits, but “it really is a whole confluence of issues” (19:12).

4. The Grassroots Movement: 'Fuck Your Headlights' (20:28–25:53)

• Paul Gatto’s Story:
  Motivated by a personal connection to a pedestrian car accident, software developer Paul Gatto becomes radicalized against car “centrism” and obsessed with headlight glare.
• Community Building:
  Paul finds a fledgling subreddit ("Fuck Your Headlights") and turns it into a robust community (now 45,000+ members) sharing stories, memes, data, and advocacy (23:16).
  • “It really was more just about complaining and letting people know that they weren’t alone in this.” — Paul Gatto (23:22)
  • Community members reject the notion that only individual aftermarket choices are to blame:
    “There's no way. Everybody is like, all these soccer moms are going out and putting custom LEDs in their SUVs. I just don't see it.” — Paul Gatto (24:07)
• Main Grievance: The forum's consensus becomes: today's headlights are simply too bright.

5. The Debate: Too Little VS. Too Much Light (25:33–31:55)

• Industry's Argument for Brightness:
  Car manufacturers and some regulators argue that brighter headlights save lives (by reducing single-car night crashes by 19% in cited studies).
  “The most compelling argument... is that, yeah, it might be annoying to you, but brighter light could be saving lives.” — Nate Rogers (27:05)
• Challenge in Measuring Harm from Glare:
  There’s no analogous data showing how glare harms safety, primarily because it’s nearly impossible to trace an accident back to glare alone.
  “Trying to measure and quantify them is hideously difficult.” — Daniel Stern (30:32)
• Pedestrian Deaths Rising:
  Pedestrian fatalities have climbed with LED adoption in the US, unlike in countries with stricter glare regulations.

6. Regulatory “Blind Spots” and Industry Trends (31:55–34:12)

• Regulatory Agency (NHTSA):
  The National Highway Traffic Safety Administration hasn’t updated rules to account for new LED realities. There’s no explicit cap on headlight brightness, and NHTSA blames aftermarket mods rather than manufacturer choices (32:32). “They're not examining if it's too bright. They're not even examining if it's affecting you negatively on the road. They are simply looking at how good it is for the driver.” — Paul Gatto (33:19)
• Consumer Responsibility:
  Drivers often want the brightest headlights possible for themselves, fueling an “arms race” on the road.

7. Possible Solutions and Their Limits (34:44–37:35)

• Divergent Priorities Among Advocates:
  • Paul Gatto: Regulate the overall brightness limit for low beams.
  • Daniel Stern: Mandate proper headlight alignment (aim).
• Adaptive Headlights:
  Car companies are developing “adaptive driving beam” tech (auto-dimming high beams), which is common in Europe but still rare in the US and isn’t a panacea—European glare complaints are rising too.
• Political Headwinds:
  The anti-regulatory environment in current US politics hampers any push for tighter standards.

8. Bigger Lessons: Regulation, Technology, and Trust (38:02–End)

• Why Headlights Matter—Beyond Headlights:
  The difficulty of reaching consensus and regulatory action on this relatively “simple” tech issue is both illuminating and worrisome—what might this portend for even bigger tech-safety challenges? “If this is how they are handling headlights, it is not very comforting in terms of all sorts of new technology.” — Nate Rogers (38:02)
• Solidarity and Fragility on the Road:
  Driving is a constant negotiation of trust with others, and unchecked technological change can fray those cooperative norms. “When we drive, we are simultaneously more powerful and more at the mercy of others than at almost any other time in our lives.” — Willa Paskin (38:22)
• Headlights as a Symbol:
  Even an issue as “small” as headlights can reveal major blind spots at the intersection of innovation, regulation, and everyday life.
