TROY, Mich.—Despite US dominance in so many different areas of technology, we're sadly somewhat of a backwater when it comes to car headlamps. It's been this way for many decades, a result of restrictive federal vehicle regulations that get updated rarely. The latest lights to try to work their way through red tape and onto the road are active-matrix LED lamps, which can shape their beams to avoid blinding oncoming drivers.

From the 1960s, Federal Motor Vehicle Safety Standards allowed for only sealed high- and low-beam headlamps, and as a result, automakers like Mercedes-Benz would sell cars with less capable lighting in North America than it offered to European customers.
