Complaints that certain Chevrolet Corvette sports cars might suffer from headlights going dark without warning are prompting an investigation by the National Highway Traffic Safety Administration (NHTSA).
You probably take them for granted and forget to turn them on from time to time, but headlights have made a remarkable journey from the lanterns they literally used to be. Now, they might be able to make rain invisible… sort of.
Results from a new test being conducted by the Insurance Institute for Highway Safety (IIHS) could prompt automakers to modify their cars by making them heavier, more expensive and less fuel efficient.
Considering their prevalence today, it’s easy to forget that just five years ago we saw our first set of LED headlights on a production vehicle. Even back then car makers were putting LEDs on concept cars to dazzle show-goers and catch the eyes of the media. But today, LED (light-emitting diode) lights are no longer isolated to just one-off concepts or premium luxury vehicles.
Porsche may have made a serious mistake in hiring an ex Wile E. Coyote illustrator to assemble their Cayenne SUVs. Sure it’s funny to see the sneaky canine’s eyes pop out, but there’s nothing funny about that happening to your car.
Jokes aside, more than 20,000 Porsche Cayennes from the 2011-12 model year, including the Cayenne, Cayenne S, Cayenne S hybrid and Cayenne Turbo are experiencing just that. It seems that there’s a chance your headlights might become detached during one of those athletic sprints to get the kids to a soccer game, or any time for that matter.
The recall was expected to begin on February 23, owners will be contacted by the automaker if their vehicle needs to be repaired.

BMW engineers are currently working on the introduction of laser light technology as the next logical step in car light development. Laser lights offer a vast improvement over the stock LED bulbs, currently used in luxury cars because lasers use less energy, are brighter, smaller, and can be directed at a smaller area.
LED lighting generates only around 100 lumens per watt, but laser lighting generates approximately 170 lumens, meaning they’re much brighter. The new technology is much more efficient and interestingly, because lasers are much smaller, designers can create very thin lights, seen on futuristic concepts. BMW also sees no reason why they can’t implement all the familiar lighting functions to lasers such as Adaptive Headlights, the Dynamic Light Spot spotlighting system and the Anti-Dazzle High-Beam Assist.
