asked by on July 21, 2016

I have a 2005 Ford Mustang. My head lights work just fine on bright, but when I turn them to dim, they stay on about 10 seconds, then go completely out (while driving) so I have to quickly switch back to my brights.

My car has 120000 miles.
My car's transmission is unknown to me.
