What does the exclamation mark inside a sun symbol indicate as a warning light?

An exclamation mark inside a sun symbol represents the lighting system malfunction indicator. Below are relevant details: Lighting system malfunction indicator illumination: When this light turns on, it indicates a failure in the exterior light bulbs. Vehicle owners should promptly visit a repair shop for diagnosis to identify the cause of the issue and replace the corresponding components. Typically, this occurs either due to the bulbs reaching their service life or wiring faults in the lighting system. Precautions to prevent lighting system damage: Avoid submerging lights in water. While driving, water splashing from the front generally doesn't affect the lights. However, during car washing when opening the hood to clean the engine and lights, water can easily enter the light assemblies. Any water ingress should be promptly dried and cleaned.
When I see the warning light with an exclamation mark in the middle of a sun symbol, I immediately think it might be a tire pressure issue, as I've encountered this several times during my years of driving. This light is usually a yellow indicator, shaped like a tire with an exclamation mark in the center, indicating that the TPMS system has detected low pressure. Possible causes include a tire puncture, pressure drop due to cold weather, or a sensor malfunction. If the light comes on, I recommend pulling over immediately and using a pressure gauge to check each tire's pressure. The normal range is between 200-300 kPa, but you should refer to your vehicle's manual for specifics. Ignoring it can lead to unstable driving, increased fuel consumption, and in severe cases, a blowout causing an accident. I've developed a habit of checking tire pressure every two weeks at gas stations as a preventive measure. If the light remains on despite normal pressure, visit a professional repair shop to inspect the sensors. Safety first—never delay addressing this issue.
Not long after I bought my new car, I saw this warning light flashing - it looked like a sun with an exclamation mark in the middle, which really made me nervous. Later I learned it was the tire pressure warning light, indicating abnormal tire pressure. Common causes include slow leaks, aging tire valves, or pressure drops after expansion and cooling in hot weather. When the light comes on, I find a safe place to stop and use a simple pressure gauge to check which tire is below standard. If not addressed promptly, it can lead to bumpy rides, higher fuel consumption, and even premature tire wear. I've developed the habit of paying extra attention during seasonal changes - for example, adding air when tire pressure tends to drop in winter. If you can't fix it yourself or the light keeps coming on, I recommend going to a 4S shop for a thorough check, as it involves driving safety.
