Bright lights mean a greater risk of being dazzled
Car makers and light manufacturers have made headlights signi cantly brighter in the past few years, including by using light-emitting diodes (LEDS), which turn on instantly and consume much less energy than other types of bulbs. LEDS, in particular, tend to be used more on expensive luxury and sports cars, due to their high cost, partly for decorative purposes and partly because they produce a longer, cleaner beam. The problem is that LED and HID lights are so intense that they can dazzle drivers in oncoming cars, even on dipped beam.
The UK has an ageing population, and as we age, our eyes cope less well with the glare of bright lights. In extreme cases, people can develop a condition called ‘disability glare’, which means it can take them up to 10 seconds to recover from the glare of bright lights.
A recent RAC study revealed that nearly two-thirds (58%) of drivers had been dazzled by the oncoming lights of cars with LED and HID lights.
The British Government and others have acknowledged that the brightness of modern car headlights is a problem and are working with the UN’S Working Party on Lighting and Light Signalling to nd a solution.
