I'd be curious to hear whether there are any real benefits to interior LED lighting. I know that some luxury cars use LED dome lights and the like. I think that I read that the new S-Class will use only LED lights on the interior, for example.
Is that just for the purpose of being distinct, e.g. a different colour, or are there other factors to it? Normal advantages of LEDs, including long life, low power usage, small size, and the ability to illuminate in a particular colour, don't seem like they'd be terribly useful in an automotive interior context. (As dome/map/accessory lights, anyway.)
