LEDs in cars for the brand statement

High-power LEDs in cars are there for the brand statement

Most engineers working with power-miserly electric vehicles (EVs) and plug-in Hybrids (PHEVs) say that the highly efficient high-brightness (HB) LEDs are currently too expensive.
But here are some conventional cars that have announced and have photos of their LED headlamps and/or daytime running lights...

...designers of these cars are using LEDs for branding, not energy efficiency. That branding isn’t necessary for the much-anticipated Chevy Volt PHEV or Tesla EV, and they’ll make do with the less-expensive traditional headlamps, at least until HB LED prices fall.

The bulb in the following article has been glowing for 107 years now.

The Tesla documentary Mad Electricity told of a story where Tesla/Westinghouse won the bid to electrify the Chicago worlds fair, and Edison was so off-put that he refused to let them use _his_ electric light bulb (like the one at the Livermore firehouse). Tesla responding by inventing altenative light bulbs including fluorescent lights.

Some good comments there.

I like the way they look.

True, they do look cool, but I think that most of these layouts could be recreated more economically with a conventional lamp, perforated metal and a bunch of plastic tubes.
