Hey Mark,

Since that is just a common 741 Op Amp you can get those in quad package design, that is, four 741s in one chip. You could then use each one to drive a different dimmer circuit - overhead done and footwells for example. Seems a lot of the newer cars have different lighting circuits that dim at different rates. Our Volvo dims the footwells quickly but the overhead at a slower rate, a neat effect.
