I've been gone a week (wow...lots of deleting I can tell already). Someone...is it TI or Mot makes a chip to monitor bulbs. I remember seeing it someplace in one of those special ap data books. Ring any bells with anyone? In a discussion with someone else, I was asked if all a car's "auxiliary" lighting could be replaced with LEDs, and/or how to monitor existing bulbs with a PIC (so you can tell when a turn signal bulb burns out, etc.)
