Acura’s Jewel Eye LED Headlights are standard on some Acura models, including the RLX sedan and MDX crossover. The systems use LEDs to provide a brighter, whiter beam than either HID or halogen headlights. LEDs also last longer than other lighting systems, and use less energy, potentially increasing fuel economy. The RLX uses the four outer LEDs and eight lenses (in four pairs, two lenses per LED) for each of the lowbeams. During the day the lowbeams are also used as daytime running lights. When the inner high beams are activated they allow you to make out distant objects 200 milliseconds faster than with traditional lights (which works out to about 17 feet at 60 mph).
MDX models use only one lens per LED, but uses basically the same system as the RLX. The low beams consist of the three outer LEDs on each side. Each lens is designed to precisely aim the light over a wide area. The highbeams consist of another two LEDs per side. During the day all 10 lenses work as daytime running lights, making sure that your vehicle is noticeable to other traffic and providing a unique look day or night.
