FARMINGTON HILLS, Mich., Nov. 22, 2016 /PRNewswire/ -- MS -- To many motorists, "vehicle maintenance" means oil changes every 3,000 miles and weekly trips to the car wash. But there's more to maintaining a vehicle than keeping it looking good on the road and tending to what's under the hood.
Recognizing the importance of nighttime visibility and how often headlamp maintenance is overlooked, Lumileds (founded by Philips) has launched a global safety campaign to increase awareness about headlight bulb technology and the importance of replacing headlight bulbs in pairs. What happens to headlight bulbs as they age? The filaments of headlight bulbs age as the bulbs are used and exposed to the elements, which include sunlight, ozone and other environmental factors. As they age, the bulbs become fragile and light begins to deteriorate, typically within two to three years of initial usage. In some cases, aging bulbs may be delivering up to 30 percent less light than they delivered when they were brand new. Why are aging headlight bulbs unsafe? When driving at night, many motorists may notice that sometimes one headlamp seems to be putting out more light than the other. While this is inconvenient, drivers may not know why it's also unsafe. When one headlamp bulb is producing a substantially weaker light output than the other, the result is an unbalanced and inconsistent light beam that can diminish driver visibility at night, when drivers' visual acuity is naturally reduced by as much as 70 percent.
