Liquid crystal in auto lights?

Has anyone heard about using liquid crystal on headlights and tail
lights? I searched yahoo for liquid crystal lamps and found this site:

No. LCD's do not generate light. They only block light.
I would think it would be simpler just to turn the light on and off
as needed.

It looks like they are using liquid crystals to control the beam
pattern.

Looks like they reduced the number of housings and bulbs to 1 per side.

Someone told me in another thread recently that the backward USA had
finally abandoned red rear turn signals.
Is this company trying to bring them back?

The LED lamp video shows a yellow, I think the halogen was designed for
GM, looks like their lamps...

This thread was started (by you I think) about liquid crystals.

Everyone knows there are yellow LEDs but why are they touting an LC lamp
with various formats of RED?

Does GM drag the USA backwards for its own commercial ends?

That's not correct at all. The US still permits red rear turn signals,
either as the brake light flashing or as a separate red light, identical
to the brake light and often right next to the brake light, so you get
"duelling reds". And what's more, the US is actively trying to force the
rest of the world to accept the red rear turn signals they (the rest of
the world) rejected entirely by the mid '60s.

The assembly will probably wind up costing more then multiple bulb
systems, and if the one bulb burns out you will have neither stop/turn
nor tail lamps.

So why are they (the US) trying to drag the rest of the world back to
the 1950s
It can not be that much cheaper when you have to have a more
complicated Turn switch.
And surley Red stop and Amber turn is better for safety.
