Ok, So I bought a used 98 mitsu eclipse spyder about a month ago. I love the car (despite the many problems I've already had with it). It is the first mistu that I have ever owned so I really don't know much about it.

One thing that has baffled me though is this little switch below my fog light button on the left. It is a little round switch with a tiny red light on it. When I flip the switch it makes a "zzzzzzrrrrp" sound and the little red light comes on.... but that seems to be about it. I've looked inside and outside of the car trying to figure out what the hell this button is or what it does, but I can't figure it out. This button also doesn't seem to be anywhere in the owners manual. Anyone know what this mystery button is?
