Light up the light switch

 I've been groping around again.

My interior light switch is a pain to find. The little pushbutton for the spotlight evades detection by seemingly moving about the headliner.

But I don't want it to be continuously lit up with a backlight.

One solution is to briefly switch the backlighting on when a person's hand is near it (so called proximity detection). This might be useful for other switches as well.

       It would be really interesting to compare the cost of (a) proximity detector vis-a-vis (b) continuously lit backlight.   

       As a wild guess the cost ratio (a)/(b) would be ~ 500.

       Perhaps it could respond with the door unlock button or proximity device on the keyfob. Then again, your lights could probably just come on automagically.

       Some of those switches are hooked into the vehicle diagnostic systems by way of the body controller. Mess with them and your mechanic will have you by the short hairs.
