Turns out that the bulb must be bad. The bulb was secure in the socket and the socket seated good in the gauge. I did pull it out and the bulb isn't lit. I have pulled it out and going to buy a new one tomorrow. The bulb is clear glass but has a small red rubber over it. I guess that's for the red illumination. Don't know if I can find a red glass replacement or not. Tomorrow's shopping trip will tell what's ready available at Autozone or Advanced Auto.
