Bright lights mean a greater risk of be­ing daz­zled

What Car? - - Advice -

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.
