New Report Confirms Headlight Glare Is Getting Out of Hand

If you’ve ridden at night recently and found yourself squinting through your visor at a sea of dazzling white beams, you’re not alone. A new report has confirmed what many of us on two wheels have been shouting about for years: Modern vehicle headlights are getting far too bright, and the headlight glare they cause isn’t just annoying, it’s dangerous.

Headlamp glare – a growing problem for everyone, but worse for bikers

To get to grips with the issue, a Department for Transport (DfT) study set out to measure just how bad glare from vehicle lighting has become on UK roads. Using an instrumented car fitted with luminance sensors, cameras, and even machine learning software, researchers recorded the brightness of oncoming lights and when drivers reported being dazzled. Alongside that, an RAC survey asked nearly 1,900 UK motorists about their experience of glare while driving at night.

The results? More than half of drivers said they’d reduced or stopped driving at night because of the brightness of modern headlights. Most of them blamed “whiter” LED headlamps and taller vehicles like SUVs for being the worst offenders.

But here’s the thing: if you think it’s bad from the comfort of a car, try dealing with it from a bike.

Riding into a wall of light

Motorcyclists can, on some kinds of bikes like cruisers and scooters, sit lower to the ground than the average car driver - much closer to the beam of an oncoming SUV’s headlights. Add to that the fact that we often lean into corners, changing the angle of our visor relative to the light source, and the glare can hit like a flashbang.

Then there’s the helmet itself. A clear plastic visor might be optically perfect in bright and dry weather, but out in the real world — speckled with rain, dust, and micro scratches — it can scatter light like a disco ball. Throw in a wet road reflecting every LED beam at you, and it becomes a perfect storm for eye strain, disorientation, and in some cases, momentary blindness.

If you’ve ever found yourself instinctively shutting one eye to block out a particularly vicious glare from an oncoming car, you already know how real the problem is.

The science of dazzle

In the on-road tests, researchers found that when luminance — the intensity of light hitting the driver’s eyes — went above 40,000 candela per square metre, the likelihood of glare spiked sharply. Around 20 per cent of all scenes recorded during the test crossed that threshold.

That’s not to say drivers experience glare 20 per cent of the time, but it does highlight how often the conditions for glare are present on our roads. Going uphill, cresting a rise, or rounding a right-hand bend all increased the likelihood of being dazzled. These are situations motorcyclists know well — when visibility is already compromised and your attention is focused on the line, throttle, and brakes, the last thing you need is a retina-melting light show in the face.

Interestingly, the study also noted that larger vehicles and those equipped with LED headlights appeared to cause more glare. That tracks perfectly with what riders have been reporting for years: tall SUVs with piercing white LEDs dominate the night, and it seems as though we bikers are copping the worst of it.

Riders turning away from night rides

The human side of the data paints an equally grim picture. More than half of survey respondents said they’d cut back on driving at night due to headlight glare — and if car drivers are finding it that bad, you can imagine how it feels for motorcyclists who don’t have tinted glass or automatic-dimming mirrors to hide behind.

For many of us, the joy of a quiet evening ride through the countryside — when traffic is light and the roads are cool — is being ruined by the modern arms race in headlight brightness. Riding at night used to be about focus, flow, and trust in your vision. Now, it’s a constant game of dodge-the-dazzle.

Why glare hits bikers harder

The combination of factors that make motorcycles so engaging to ride also makes them more vulnerable to glare.

• Lower seating position – puts your eyes directly in the beam path of taller vehicles.
• Helmet visors – introduce reflections and scatter light, especially when dirty or wet.
• Lean angles – change the visor angle and can make glare worse mid-corner.
• Wet roads – reflect light upwards, effectively doubling the intensity.

It’s a sensory overload, and for new riders or older ones with reduced night vision, it can be genuinely intimidating.

What can be done?

The DfT’s report doesn’t just identify the problem, it also suggests what could be done to fix it. Key recommendations include:

• Regular glare surveys to monitor how serious the issue is becoming.
• Public education on how and when drivers cause glare (for instance, by failing to dip headlights correctly).
• Further research into headlamp design, especially around LEDs and tall vehicles.
• Updated lighting regulations, focusing on luminance (how bright light appears to human eyes) rather than just intensity (how much light the lamp produces).

Crucially, the report notes that current lighting tests don’t account for the observer’s perspective — meaning a light can pass regulations but still blind someone on the road.

Dazzled but not defeated

For riders, the solution might come sooner through smarter design — adaptive headlights that automatically adjust beam height based on terrain, or regulations that limit the glare from LED and matrix lights. But until then, we’re left to cope.

That means keeping visors spotless, and as scratch-free as possible, while using an anti-fog coating or a Pinlock to avoid internal reflections would be sensible. Headlight glare isn’t just a comfort issue. It’s a safety issue. Glare robs you of information, steals reaction time, and increases the chance of missing hazards on the road ahead. And for motorcyclists, even a momentary lapse in vision can have serious consequences.

So next time you’re out after dark and that oncoming SUV lights up your world like a welding torch, remember: it’s not just you being dramatic. The data backs it up. Our roads are getting brighter, and not in a good way.
