Autodimming and compass
Slots straight onto the standard mount and wires into the light (just botched for now). Each function has on/off switch so (hopefully) no battery drain.
And if you're thinking it's a bit big - it's not.

There are hundreds of these on ebay as they come standard on many cars - they are made by Gentex and some include temp sensors/display, garage door opening, LED map lights and even LCD displays for reversing cameras!.
