why are my running lights and tail lights staying on all of a sudden.

I think those are actually your parking lights. Check out this thread here, you have the same button: http://www.cargurus.com/Cars/Discussion-c3468_ds577751#msg319118

Also, after you've seen the above, please let me know if that is or is not the fix :)

There is a switch on the steering column that turns on the parking lights. Below is a piture of the switch on my 2001 Subaru. If you see the orange the lights are switched on
