As automakers start churning out electric vehicles, some features that help boost the car's range have become permanent necessities -- things like regenerative braking and lightweight materials. Now, it seems LED headlights will need to be added to that list.
According to bulb manufacturer Osram Sylvania, replacing halogen bulbs with LEDs in electric vehicles can add six miles to their range. Far more efficient LEDs draw less than 25 percent of the energy that halogen bulbs do, and in a car that depends solely on battery power for its range, that makes a nice difference. Six miles may not seem like much, but all EV owners would be grateful for six more miles to find a charging station on a long trip or six miles may make the difference between making the roundtrip to work or not for some people.
LED bulbs have other benefits too like extremely long life and high vibrating tolerance, meaning the bulbs could last as long as the car does. The carmaker may have a little extra cost upfront, but the driver will save some money with less charging and without the need for replacing the head lamps.
