Lights at night do not light up the speedometer. on 1996 Ford Taurus

After some trouble this week of replacing the battery, starter & knocking a hole in the oil filter so a new filter & oil, the new thing is: there is no lights showing on the dash. What next? Is it a fuse or a bulb? And where would I find it to replace it? Trouble in Texas...
