LED Headlamps On The Way
Having worked with white LEDs (in an interior indicator application) quite a bit in the past 3 years, I can say that indeed they've got significant advantages over incadescent bulbs - smaller, "whiter", cooler, more efficient, and certainly much more durable (a glow-hot filament and vibration are poor companions). And for all these reasons, I've been switching over to LED flashlights (I'm partial to Streamlight's low-cost models such as the 3N and 4AA). So I'm anxious to see them put into mainstream use for car headlamps, as well as building lighting.
Plus, it'd be nice to find a better use for tungsten than to burn it up and throw it away (it should be noted that China controls approximately 45% of the world's known reserves and produces 70% of the world's tungsten output).
