It's not a factory gauge! it's an aftermarket one! I know the oil pressure will drop as the engine warms up, but I get a lower reading when the lights are turned on. An elec oil press gauge is juts a fancy ohm meter, so something weird is going on electrically. This has happened with toher guages too, not just this one.
