Villanova Prof. Says Laser Technology May Mean Brighter, More Expensive Car Headlights

VILLANOVA, Pa. (CBS) – Your car’s headlights could be getting a new look.

With lasers, the German automaker BMW is already planning the demise of xenon lamps and LEDs, only now becoming standard over halogen headlights.

BMW says lasers shine a thousand times brighter than current technology.

“The benefit would be higher energy efficiency, so you get more output power for the amount of energy that you’re putting into the laser,” explains Pritpal Singh, professor and chairman of the Electrical and Computer Engineering Department at Villanova University.

Singh (right) says the light from a laser headlamp would be very bright.  But what about all the times we’ve been warned not to look directly at lasers?  BMW says there would be no risk to other drivers, pedestrians, or animals.

“The intensity can be controlled, so it’s not zapping you with a high-focused beam,” explains Singh, so you presumably won’t be able to “set your phasers to stun” to deal with that sluggish driver ahead.

But you might have to reach deeper into your pocket when laser headlights are available in the coming years, Singh notes.

“I think the biggest question would be the cost, because lasers are significantly more expensive than LEDs,” he says.

    Deport the snake charmer. I don’t need brighter lights from oncoming traffic.

    What a dumb idea. The only reason you would need such bright lights is to avoid hitting a skunk.

    This is a bit ridiculous! How much light do we need to drive a car at night? I guess it would be just as ridiculous to suggest driving during the daytime only. Who paid for this research?
