I got a green LED already set up for 15V (or 12V??) from Radio Shack for just a few dollars. Other colors were available. If you're an electrical nerd you can probably do it for less than I paid.

When your driving on the freeway and the fans free spinning,
doesn't that cause the led to light up a little?
