Speaking of headlights -- pretty soon all cars and trucks will come standard with high output Lumiled (Philips) LED headlights. A couple years ago I was on the engineering team at Plansee that developed the copper-tungsten cooling element that keeps them from burning up. I was among the first to witness them in action. They will be brighter, consume less current, and last many times longer then conventional bulbs. Audi and GM are currently designing them into upcoming models.
