A gauge is borderline on its mark to set the light

A gauge just at the point at which an alert is triggered, can cause warning lights to activate and deactivate. One example is the temperature gauge. If the engine temperature is very high, but the cooling system is still operating, the temperature may very just at the point to cause a warning as the coolant circulates.

Causes

Depending on which warning light is activated, or which gauge you are looking at, this can be caused by a variety of issues.

Poor Coolant Circulation

If the coolant is not circulating properly, the engine temperature may fluctuate just enough to trigger a warning light.

Low Oil or Other Liquid

If an engine is low on oil, it may be at a point just at the sensor so that slight vibrations and movement will cause the oil to slosh around and activate the sensor.

The same principle applies to other liquids such as coolant or gasoline. There may be just enough to keep a warning from being activated.
