Your Car's Headlights Are Probably Terrible: IIHS

The Insurance Institute for Highway Safety has started rating headlights, and just released a report that takes a dim view on the performance of most midsize cars.

Only one vehicle out of 31 testers earned a rating of “good” from the road safety nonprofit, with the bulk of midsize vehicles earning a rating of “marginal” or “poor.”

The results are even less dazzling when you take into account optional lighting packages, which pushed the number tested to 82. Even then, it was only the LED-equipped advanced technology package on the Toyota Prius V that earned the IIHS’s acclaim.“If you’re having trouble seeing behind the wheel at night, it could very well be your headlights and not your eyes that are to blame,” said David Zuby, IIHS vice president and chief research officer, in a statement.

The headlight test, performed at the Vehicle Research Centre in Ruckersville, Virginia, recorded the illumination of nighttime road obstacles by regular low beam settings from five different approach angles. It also measured glare for oncoming vehicles.

When the results were in, researchers found the results didn’t discriminate along class lines, or nationality. The headlight performance of many luxury vehicles were outclassed by cheaper models.

The bottom of the headlight barrel are the halogen eyes on a BMW 3 Series. It was only optional equipment that allowed BMW to climb up into the “marginal” category.

“A driver with those headlights would have to be going 35 mph or slower to stop in time for an obstacle in the travel lane,” the IIHS said of the standard halogen setup.

The Mercedes-Benz C-Class and CLA earned a solid “poor rating,” as did the Cadillac ATS. Among lesser price tags, the Chevrolet Malibu scored poorly, but so did the Hyundai Sonata, Kia Optima, Nissan Altima and Volkswagen Passat.

The Subaru Legacy, Ford Fusion and Toyota Camry made it into the “marginal” category, where they share space with the aforementioned Bimmer (plus the 2 Series), Audi A4, Acura TLX, and Lincoln MKZ.

Earning an “acceptable” rating were the Mazda6, Infiniti Q50, Nissan Maxima, Honda Accord, Lexus ES and IS, Volkswagen Jetta and CC, Subaru Outback, and Volvo S60.

Despite advances in road illumination — high-intensity discharge (HID) lamps, LEDs and curve-adaptive headlights — the poor results mean technology still hasn’t caught up to real world driving scenarios.

With the IIHS now breathing down their necks over headlights, expect automakers to frantically upgrade their badly performing models before next year to avoid embarrassment.

    The worst headlights I had seen were on a Lincoln Mark VIII that I owned some time ago. They were barely better than DRLs. The best headlights I used were on my Toyota Tundra 5.7. They were halogens, but were very powerful. They illuminated the road like the eyes of God on low beam. High beam was searing and could easily illuminate 200 feet ahead. I miss those headlights.

    Got a chance to see the BMW seven series laser lights in action at 250km/h on a BMW test vehicle on the way to Dresden. Very, very impressive and the way part of them moves to read passing signs is creepy. Now I'm sure all of us tootling along at 90Mph here in the US will never need such bright lights and I had no idea what the poor bastards on the other side of the road saw but these were the most impressive thing about the new seven - oh and also the way the car can move out of a parking space without anyone being inside while being controlled from your keychain remote!

  • Bd2 Excellent article, very nice car. Thank you Murilee.
  • Make_light I like Subarus, and I often think they don't get enough credit for how they drive. Lots of people say it's the faux-rugged image that accounts for their popularity, but they also drive with a solidity and plantedness that's absent from a lot of the Japanese competition. That being said, this thing is ugly. I never felt that Subarus were as ugly as commenters claim they are. Boring, sure, but not necessarily ugly. But between this and the refreshed Legacy, it's like they're trying to make their vehicles look as incohesive and awkward as possible.
  • SCE to AUX I think the 2.2 was a pretty durable engine.
  • Rochester We'll probably be trading in our 2018 Touring Edition Forester for the next model, and are waiting to see what the Hybrid is all about. Would be nice if they disclose whether or not it will be a plug-in Hybrid.
  • CEastwood I have a friend who drives an early aughts Forrester who refuses to get rid of it no matter all it's problems . I believe it's the head gasket eater edition . He takes great pains regularly putting in some additive that is supposed prevent head gasket problems only to be told by his mechanic on the latest timing belt change that the heads are staring to seep . Mechanics must love making money off those cars and their flawed engine design . Below is another satisfied customer of what has to be one of the least reliable Japanese cars .https://www.theautopian.com/i-regret-buying-a-new-subaru/
