Ambiance Lighting

While driving in a 03 BMW 330ci I noticed they have what BMW calls Ambiance Lighting.  And all it was, was 2 amber LED's in the over head console that Shine down on the center console area.  I thought it would be a pretty cool Idea to add something like this to my car (2000 Mustang GT convertible) after doing some searching I came across what seems like the only after market manufacturer that seems to have anything like it ( www.gentex.com) they have it built into the mirror.  Unfortunatly I only found one place to buy it at a rediculous $250.00 

Now In my mustang my mirror has my map lights built into my mirror.  I was wondering if anyone had done something like this and or has an idea on how to make it possible?   These lights that were in the BMW were extreamly dim. just enough to light up the console.

Any help/suggestions are appreciated

Thanks Nick

rig a LED inside the console, and have have some resistor i believe, to dim it. have it on a push button switch- open console it lights up. Something like that.
