The oil pressure light is an important warning indicator on a vehicle's dashboard. It alerts the driver when the oil pressure in the engine is too low, which can lead to serious engine damage if not addressed. Low oil pressure may result from insufficient oil levels, a faulty oil pump, or a clogged oil filter. When the oil pressure light illuminates, it is crucial to stop the vehicle as soon as it is safe to do so. Checking the oil level and condition is the first step. If the oil level is adequate, further investigation may be needed to identify the underlying issue, such as a malfunctioning oil pump or a leak.
