How new glare-free headlamps will prevent drivers being dazzled

Glare-free headlamps which prevent drivers being dazzled by on-coming lights could be on a car near you in the very near future. In the 70s, the Manfred Mann hit Blinded by the Light could be heard coming from cars all over Britain. More recently, the song’s chorus has been adopted as a protest against super bright car lights.

Ever since the introduction of Xenon or High Intensity Discharge (HID) lights in the early ’90s on the BMW 7 Series, and Light Emitting Diode (LED) lights in cars such as the 2006 Audi R8, the brightness and intensity of headlamps has increased.

That’s good news for drivers of cars fitted with these powerful lights: seeing further down the road reduces the chance of accidents and driver fatigue. But if drivers forget to dip their lights, it can temporarily blind oncoming traffic.

“Ask any driver what the most annoying habits of other drivers are and sooner or later the subject of people who don’t dip their headlights will come up,” says Michael Koherr, a research engineer for Ford who specialises in vehicle lighting.

Dazzling headlamps cause drivers to crash

According to the most recent government figures, dazzling headlamps do cause accidents and even deaths. Police record the contributing factors of accidents in Britain. One of those is ‘dazzling headlamps’. In 2014, police who attended the scene of the accident reported this as an influence in 10 fatal crashes, nearly 70 serious accidents and over 250 slight accidents. But some campaigners point out that minor accidents, which often aren’t attended by the police, but can be distressing for drivers and may result in insurance claims, go unrecorded.

A new generation of headlamps can prevent glare

The problem has been under the spotlight for decades. And Michael Koherr says it’s not just drivers being dazzled that is the problem. Some motorists don’t switch to high-beam when the road ahead is clear, which can be especially dangerous on unlit, rural roads.

“We found that some drivers are so concerned about dazzling other road users that they don’t use high beam at all,” Koherr said. The Department for Transport (DfT) describes rural roads as often ‘more sinuous and narrow in nature with blind blends, dips and other distractions which means that it is easier for road users to travel too fast to miss these dangers or fail to slow down when approaching them.’

Now, however, drivers needn’t lift a finger. Technology has allowed engineers at Ford to develop new systems that effectively take over the operation of the lights for the driver, and even adapt the light pattern of the headlamps according to driving conditions, traffic and obstacles such as pedestrians or cyclists.

Called Glare-Free Highbeam, the system was developed at Ford’s European research centre in Aachen, Germany, and can be fitted to cars drivers can buy today – including the Mondeo, S-Max and Galaxy family cars – for £900. It is a sign that the once exclusive technology is filtering into everyday cars.

How do glare-free headlamps work?

Ford says its Glare-Free Highbeam works with other lighting systems to adjust the headlight beam angle and intensity to one of seven settings according to speed, ambient light, steering angle, distance to the vehicle in front and windscreen wiper activation.

Adaptive headlamps will become as common as radios and air-conditioning

Ford believes such smart lights will eventually become a standard feature on all its cars. “Like all new technologies, it starts at the most expensive end of the market with the margin to invest in the tech. Then the price comes down per unit and smaller cars can tap into it in the future,” a spokesman revealed.

The car maker is not alone in developing intelligent headlight systems that can adapt the spread of light according to what sensors fitted to the vehicle see on the road ahead. Audi, BMW and Mercedes have offered so-called smart lights as a cost option on many of their popular models – not just expensive, flagship cars.

Having tried a number of different makers’ system on the road, it’s impressive to find how seamless the technology has become. Audi’s system will even integrate with sat nav to anticipate the road ahead.

“You still have to really want it,” said a BMW spokesman, “but like air-conditioning, airbags or head-up displays, it will probably become standard on cars throughout the BMW range over time.”

So next time you order a new car, or buy a relatively young used car, sing along to Blinded By The Light for all the right reasons, and consider choosing glare-free adaptive headlamps.

    Hid led and xenon lights are all way to bright. I dont see why you need lighthouse grade bulbs for the road. The irony is that your excuse for them is to be seen…. yet your lights are so bright we can not see you because you are blinding us. They all dazzle and blind and are just plain stupid and irresponsible. Fashion/ fad/ weapons??!!! but remember this….when you blind oncoming traffic its you that will be the cause of your own head on collision.

    These very bright lights should be banned, they are unnecessary and dangerous to oncoming drivers.

    I constructed a flip-down screen angled to BLOCK ALMOST ALL LIGHT from the oncoming side of the road. Its the only reasonable defence against dazzle. The authorities are not only not interested, but stated to me that “the brighter the better” was the correct logic. Logic like this can only come from a highly perverse place.
