We had a 95 ranger at work that all the dash lights burnt out on...there was 1 light still working the first time I drove it, and that last light burnt out around 450,000 miles, but I highly doubt they were all original, lol.
My 98 with 134,000 has at least 2 burnt out (fuel gauge and voltage are 100% dark).
The 07 ranger at work already has one dash light burnt out (right in the middle of the speedometer)...i think it's at around 60,000 miles right now.
While you're replacing the bulbs I'd recommend putting some LEDs in there so you don't have to ever replace them again. www.v-leds.com
seems to be a good source; I'm sure there's plenty of other places to get them though.
