考虑事项包括修改前照灯标准以及打击非法销售功率过强灯泡的行为
随着夜晚变长、时钟回拨，英国政府开始关注对向车辆头灯的刺眼强光问题，正考虑修改车灯标准并打击非法销售超高功率灯泡的行为。
英国汽车服务公司RAC周二发布的一项调查显示，超过四分之一的驾驶员表示，明亮的车头灯让他们对夜间驾驶感到紧张。
这一突出问题有望在政府年底前出台的新道路安全战略中得到解决。据悉，政府随后将向联合国监管的国际车辆照明法规提交修订提案。
政府于18个多月前委托开展了关于汽车前照灯眩光成因的独立研究，预计最终研究成果将在新战略出台时公布。
这项道路安全战略预计将包含一项承诺，即对不同品牌和型号的车辆开展进一步研究，以准确识别哪些设计因素可能导致眩光加剧。
可能的影响因素包括：亮度更高的LED（发光二极管）车灯数量不断增加，以及驾驶SUV的人数大幅上升——这类车型的车灯通常位置较高，容易直射小型车辆驾驶者的眼睛。
老年司机尤其容易受到影响，因为他们的眼睛在被强光照射后需要更长时间才能适应。
相较于传统的卤素灯，LED灯具有显著的节能优势，在降低英国碳排放的单项技术中贡献最为突出。
对汽车而言，这意味着减少用于车灯发电的燃料消耗，从而节省成本并降低污染。根据验光师学院的数据，与卤素灯相比，LED每单位电力产生的亮度是其八倍。
然而，在老旧车辆上改装LED车灯可能引发问题，因为这些车辆的设计并未考虑更亮的灯光，这意味着对向行驶的车辆可能会受到更强的光线干扰。
据了解，负责机动车年检（MOT）的英国驾驶员和车辆标准局已加强对车辆前灯的检查。安装不合规前灯灯泡的车辆将无法通过年检，非法销售此类灯泡的商家可能面临1000英镑罚款。
英国交通部发言人表示：“我们深知车头灯眩光问题令许多驾驶员困扰，尤其在夜幕降临时更为明显。为此我们委托开展了独立研究，以更深入地理解眩光的成因及其影响，相关结论将为即将出台的道路安全战略中的新措施提供依据。”
与此同时，英国驾驶员与车辆标准局（DVSA）已加强监管力度，以打击非法改装车头灯泡在道路上的销售行为，违规者最高可面临1000英镑的罚款。
英国汽车协会（RAC）高级政策官员罗德·丹尼斯表示：“不幸的是，对许多驾驶员而言，每年夜幕提前降临的同时，还会迎来另一个不受欢迎的现象——他们认为过于明亮的车头灯会因眩光和不适感而增加驾驶难度。”
尽管冬令时调整后，大多数人不得不更频繁地适应夜间驾驶，但车头灯眩光成为引发驾驶焦虑的主因，这一事实凸显了解决问题的紧迫性。与此同时需注意，更明亮的车灯能让驾驶员更清晰地观察前方路况——因此需要在两者间取得平衡。
验光师学院建议驾驶员通过确保挡风玻璃和眼镜清洁，并调整车内后视镜以减少后方车辆眩光的影响来缓解眩目问题。该机构表示：“当遇到迎面而来的强光时，请保持眼睛睁开，短暂看向路缘或路边，直到视线恢复清晰。”理想情况下，受眩光影响的驾驶员应减速并在安全情况下停车，直至视力恢复正常。
Considerations include changes to headlight standards and clampdown on illegal sale of overly powerful bulbs
With nights getting longer and the clocks going back, the bright glare from oncoming traffic has the attention of the UK government, which is considering changes to headlight standards and a clampdown on illegal sales of overly powerful bulbs.
More than a quarter of drivers say bright headlights made them nervous of driving in the dark, according to a survey published on Tuesday by the RAC motoring services company.
The glaring problem is expected to be addressed in a new road safety strategy from the government before the end of the year. It is understood the government will then propose amendments to international vehicle lighting regulations overseen by the United Nations.
The government commissioned independent research on the causes of headlight glare more than 18 months ago, with the findings finally expected to come by the time of the new strategy.
The road safety strategy is expected to include a pledge of further research on different vehicle makes and models, to identify exactly what design factors may be responsible for increased glare.
Possible factors might include the increasing number of brighter LED (light-emitting diode) headlamps, and the huge rise in the number of people driving SUVs , whose headlights are usually higher, pointed into the eyes of drivers of smaller cars.
Older drivers can be particularly affected because it takes their eyes longer to adjust after being dazzled.
LED lights offer huge energy-saving benefits over older halogen lights and have made one of the biggest contributions to cutting the UKs carbon emissions of any single technology.
In the case of cars, this means reducing the amount of fuel used to generate electricity for lighting, saving on costs as well as pollution. LEDs generate eight times more light for each unit of power compared with halogen, according to the College of Optometrists.
However, retrofitting LED lights on older cars can cause problems because they are not designed for the brighter lights, meaning more light may be visible to oncoming cars.
It is understood that the Driver and Vehicle Standards Agency, which carries out MOT roadworthiness tests, has stepped up checks on headlights. Cars with unsuitable headlight bulbs will not pass the MOT, and sellers of illegal bulbs could face a 051,000 fine.
A Department for Transport spokesperson said: We know headlight glare is frustrating for many drivers, especially as the evenings get darker. Thats why we commissioned independent research to better understand the causes and impact of glare, which will inform new measures in the upcoming road safety strategy.
Alongside this, DVSA has stepped up surveillance to intercept the sale of illegal retrofit headlamp bulbs for on-road use, and anyone caught could face a fine of up to 051,000.
Rod Dennis, the senior policy officer at the RAC, said: Unfortunately, for a lot of drivers the annual onset of darker evenings coincides with another unwelcome arrival C that of overly bright headlights that they believe make driving more difficult due to dazzle and discomfort.
While most of us have no choice other than to adapt to driving at night more often as the clocks go back, the fact headlight glare is the leading cause of nervousness underlines its a problem that needs tackling. At the same time, its important to remember that brighter headlights can give drivers a better view of the road ahead C so theres a balance to be struck.
The College of Optometrists advises drivers to mitigate glare by ensuring windscreens and glasses are clean and adjusting interior mirrors to reduce dazzling from vehicles behind. It says: When faced with bright oncoming headlights, keep your eyes open and briefly look to the curb or side of the road until you can see clearly again. Dazzled drivers should ideally slow down and stop C if safe C until their eyes have recovered.
