That's true in general, but high-powered LEDs are still somewhat inefficient and very sensitive to high temperatures so they still require a lot of heat-dissipating hardware (heatsinks and even fans, like people already pointed), which adds in extra weight and bulk, so the difference is not very significant.

Theoretically - yes, however a lot depends on build quality of LEDs and their circuitry... We have LED traffic lights everywhere, I've seen plenty of them become defective after a year or so... Also, replacing full LED assembly (with multiple LEDs) can be much more costly than old-fashioned lightbulbs. Try and look at Audi forums how much the LED headlights cost to replace out-of-warranty, you'll be surprised.

Yes, they most likely will be in all future cars, BUT there's currently no NEED for full LED headlights at all in gasoline-powered cars (where their efficiency is basically irrelevant) aside from "cosmetic" effects They may last longer than xenon headlamps BUT you're paying up to $2000 for this option right now, you'll probably spend less than that on xenon lightbulbs (unless you have a defective ballast/bulb) over the lifetime of your car
