Change dash light bulbs in 1996 ford ranger?

You must remove the instrument panel. There a several forms that show how to remove the panel.

The bulbs are in plastic holders. They are a wedge base bulb and pull straight out of their holder. The gauge illumination bulbs are #194. Don't believe the bit of all bulbs are #194. The warning light bulbs are a smaller bulb. I think they are a #73.

Both these bulbs are available from Mouser electronics under a dollar. To remove the bulb holder just twist counter clockwise. Takes a lot of force.
