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.
There's good news and bad news regarding the sub-systems of today's late-model vehicles. The good news is that new engines and transmissions are more trouble-free than in the past. The bad news is that the infotainment and DVD players are still prone to be "buggy."
For decades, the corporate path to the chief executive's office has often passed through engineering. Automotive, computer, electronics, and oil companies have frequently drawn their leaders from the engineering ranks.
The Texas Motor Speedway has flipped the switch on a high-definition video board that uses 14 million LEDs, weighs more than 200,000 pounds, and is 80% larger than the Dallas Cowboys' world-renowned scoreboard.
