I saw a 1997 4Runner today with fog lights in the center of the front bumper with a swithch in the knock out on the left side of the dash. Was this stock and where can I get this set-up? It looked like the two lights were mounted on the ends of a black tube in the center of the front bumper.

If they were in the center of the bumper, then those are driving lights. Chances are they are NOT stock. You can buy a pair at your local auto parts store. They take about an hour to install and they make driving at night MUCH easier
