I did it a long time ago....very easy. Nowadays more cars are starting to have the lights like Audis, Mecedes, Acuras etc. Most of the time the light emanates from the underside of the rearview mirror. Mine are mounted into the panel where the sunroof switch is and are tapped into the lighting for the switch. My LEDs are blue though because I like the blue tone at night. As a matter of fact my interior is tricked out with a number of subtle sexy lights. Not that it matches the orange hue of the dash lights but it is a kool contrast everyone notices in my car... I have 2 more small blue LEDs that light up the floor of the rear seat too. Plus I have black lighting under the driver and passenger side of the dash. Interesting the black lighting with the blue LEDs are a matching combo. And one of the coolest things are my blue lighted door sills that say "BMW". I was careful not to go overboard with the lighting. Everything was installed clean, recessed, tasteful and out of sight. Best thing is everything is switch controlled so I can choose on my mood when I want the lights or not. I think it costed me about $30 to do all this. Anyone with imagination can do it too....The wiring is not rocket science.
