Is my truck 4-Wheel Drive and if so how do I turn it on?

This may sound like a dumb question but I just recently got a 1995 Ford F-150 xl and it never crossed my mind that it would be four wheel drive. Howver today when I was driving it i noticed that a little to the right of the spedometer there was a spot that said 4x4 but it wasn't glowing. I looked all over the place for a spot where the switch or lever might be but found nothing. Any help would be greattly appreciated.

Yeah

The easiest way to tell is to look under the truck and see if there's a 4wd drive line. I'm guessing you see the 4x4 on the dash because all ford trucks use the same dash, 4wd or 2wd.
