James, now a day's most of the incandescent and traditional illuminant lamps are getting replacing either by CFL or LED bulbs. When we look in energy saving angle LED lamps are the preferable one, but its little bit expensive when compare with CFL. I think in coming days, when mass production happens, the cost may come down further. In future, it may replace all the existing lighting sytem across all sections like automobile domain, street lights etc

naperlou, Based on the amount of heat being dissipated by the LCU/LEDs, it makes sense to remove the headlamp driver function from the Body Control Module (BCM). The LCU will be control by the BCM through CAN (Control Area Network) communications.

The idea of being able to control the output of the light to such a degree is going to prove very useful to the automotive industry.  I wonder what other industries might be able to take advantage of this flexibility.

I do marvel at contemporary automobiles.  As one who works with microcontroller devices in many types of applications, it is no supprise that the lights mentioned here use a microcontroller to control functionality.  Whatius really interesting is that the lighting microcontroller talks to the body control microcontroller. 

This is just one step to an optimal lighting architecture that is automated.  I can remember the days when I put driving lights (with a 1 mile range) on my Austin Healey.  I had to be careful of where I used them, but no longer.  Just program the LED  lights and they will sense the on-coming traffic.
