Can your headlights keep you dark?

Only one Toyota Prius V model has achieved good results.

The LED headlights in the Prius V test can illuminate a straight road enough to see 387 feet of pedestrians, bicycles or obstacles ahead.
At this distance, the vehicle can travel 70 metres. p. h.
There\'s still time to stop.
But the halogen lamp of the BMW 3 Series, the worst-
Rated models can only illuminate 128 feet ahead.
At this distance, the vehicle cannot travel more than 35 metres. p. h.
According to the study, there is still time to stop.
It\'s important because more than 32,000 people died in traffic accidents last year.
Half occurs at dawn and dusk at night or with low visibility.
The reason for the big performance gap is that headlights help drivers see more than just the brightness of the bulb, even the type of bulb used, and more, says David Zubi, executive deputy researcher at the Institute.

\"We found that the same bulb, depending on the reflector or lens it goes with and how it fits on the vehicle, can give you very different visibility on the road, he said.
Things get more complicated.
Consumers cannot buy more expensive models, nor can they add more expensive technology packages, and will inevitably expect better headlights, the report said.
Basic model four halogen lamps for price economy-
For example, menbentian accord received an acceptable rating in two higher-priced Mercedes-Benz, while halogen lamps and LED headlights
Mercedes-Benz models were rated poor.
Because there are no reliable leads, such as the price of a car or the type of light, it is difficult for consumers to determine which vehicles can provide the safest visibility, Zuby said.
He suggested that car buyers check the rating of the Institute.
The report comes as halogen lamps are being raised-
Discharge of strength (HID)
In many vehicles and LED lights.
Headlights that help to see the curves around them are becoming more common as cars turn to turn.
While these changes can have an advantage, the report says, good performance cannot be guaranteed.
The researchers tested the headlights after dark on the institute\'s test track in Va Ruckersville.
When the vehicle is traveling on five different routes, a special device measures light from a low beam and a high beam: a straight line, a sharp left curve, a sharp right curve, the left curve of the gradient and the right curve of the gradient.
The researchers also evaluated the headlights for excessive glare.
They were surprised to find how much the headlights changed from the base model to the higher trim or accessory pack, Zuby said. Eighty-
The 31 2016 models evaluated in this study have two different headlights systems. To get the top-
Rated headlights for Prius V, consumers must purchase an advanced technology package that can only be provided at the top trim level.
Standard halogen lamp without high matching
The less expensive Prius V trim level beam assist was rated poorly. High-
Beam Assist automatically adjusts the headlights range for front or oncoming vehicles.
Toyota officials declined to comment.
BMW said in a statement that the company was disappointed with the rating but was still confident that its headlight system was \"very effective\" for a variety of models at different prices \". Mercedes-
Mercedes-Benz said in a statement that it was \"very surprised\" by the test and still \"believes that our lighting system provides important security benefits for the real world \".
\"The government\'s criteria for judging the performance of headlights are basically unchanged,\" Zuby said, because they were delayed in the 1960 generation.
\"In the standard, they are measuring the light emitted by the light source --
Right in front of the bulb, essentially-
\"Don\'t look at how the light is projected along the road, and that\'s what our tests do,\" he said . \".
The institute hopes its research will encourage the National Highway Traffic Safety Administration to raise standards or inspire automakers to make better headlights themselves, Zuby said.
