The university’s transportation institute believes LED usage will increase significantly in the next five years.

Engineers at the institute said LEDs, a form of solid-state light, have numerous benefits, but also potential issues, and more research is needed.

Most new cars have LED headlights, a trend that has agitated thousands of drivers who say the lights are too bright and bad for the eyes. Research, online petitions and news stories—including a Consumer Reports article—all have targeted bright headlights like LEDs.

One Change.org petition, supported by the American Motorists Association, has nearly 15,000 signatures, asking the National Highway Transportation Safety Association to ban bright LED headlights.
