Tändningslampor

Tändningslampor, often referred to as the ignition warning light or engine warning light, are crucial indicators on a vehicle's dashboard. Their primary function is to alert the driver to a potential problem within the engine's ignition system or other critical engine-related components. When the ignition key is turned to the "on" position, most of these lights will illuminate briefly as part of a system check and then extinguish if all is functioning correctly. If a tändningslampa remains illuminated after the engine has started, or if it flashes unexpectedly, it signals that the vehicle's onboard diagnostic system has detected a fault.

The specific meaning of a tändningslampa can vary depending on the vehicle's make and model, and the color of the light itself often provides a clue. A steady red light typically indicates a more serious issue that requires immediate attention, potentially including low oil pressure or overheating. A steady yellow or orange light usually suggests a less urgent problem, such as a loose gas cap or a minor emissions system fault, but still warrants investigation. A flashing tändningslampa, regardless of color, often signifies a severe misfire that could damage the catalytic converter and requires prompt diagnosis. Ignoring a lit tändningslampa can lead to further damage and more costly repairs. Consulting the vehicle's owner's manual or seeking professional diagnosis is recommended when this warning light appears.
