"AUTOMOTIVE lighting is undergoing a quiet revolution * * * LED lamps are smaller, run cooler and use less energy than standard automotive lamps.
with LED: "Headlights and taillights can now be constructed in different shapes and patterns that, much like a car’s tail fins in the 1960s, immediately identify a particular make and model.
"use [LED] light to make nighttime driving safer. By combining LED lamps with cameras, a vehicle’s headlights can be more than just a set of low and high beams, and instead continuously alter their light patterns to exactly fit the immediate road conditions. * * * Given an LED’s smaller size, cars can pack more bulbs into each headlight, each of which can then be turned on and off to create unique light patterns based on road conditions and the amount of oncoming traffic. This ensures that other drivers are never blinded by oncoming headlights, while the driver of the vehicle using the system receives an optimal view of the road [but current US restrictions, set by National Highway Traffic Safety Administration, limits its application].

I changed my old halogen lamp and replaced it with a led lamp.
