I think this is a step in the right direction. Dimmable LED lights that are "warm" would be a great product for the home, much less cars. I have many dimmable lights in my home. Alas, all are incandescent. The dimmable LEDs available have a very narrow "dimming range."
I intend to do something similar, Charles. At the moment, I'm in a temporary location, but when if the lighting is similar when I get a permanent home, I expect to be getting myself a desklamp that will throw some warmer light on my work area. My previous company actually supplied halogen desklamps for that purpose and one of the part-time student admins who works for me already brought in an incandescent light for this purpose.
That's a really clever technique. I worked with a pinball company (OK, there's really only ONE pinball company), and their solution was to mix additional colors in with the white LEDs to make them look a little less ghostly. Reflectors were also used to warm the white LEDs up a little bit. As you can imagine there are quite a few bulbs in a pinball machine and finding a solution was really important.
White LEDs did make great replacement for flashers, which was really a 12V bulb hit with 24V, as you can imagine, they wear out pretty fast.
