Yellow bulb with an exclamation mark, this is the lighting fault indicator light, indicating that there is a fault with the vehicle's lights. Solution: Go to a 4S shop for inspection and repair as soon as possible, or you can check it yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to see where the problem lies. The exclamation mark is a common fault warning in cars. In addition to the yellow bulb with an exclamation mark, there are four other forms of exclamation marks: an exclamation mark inside a triangle, an exclamation mark inside a yellow gear, an exclamation mark in the middle of a bracket and circle, and an exclamation mark in the middle of a bracket with a line below. Here is a detailed analysis: General fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates that the car's general performance or components and functions have malfunctioned. Mainly includes parking sensor failure, fuel cut-off system intervention or failure, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to a 4S shop for inspection and repair to identify the source of the fault. Automatic transmission fault: An exclamation mark inside a yellow gear. This is the automatic transmission fault warning light, indicating that there is a fault with the transmission or the transmission lubricant is below the normal range. The transmission oil needs to be replaced in time. Brake system fault: An exclamation mark in the middle of a bracket and circle. This represents a warning for the brake system, mainly indicating a brake system failure or low brake fluid level. The brake system needs to be inspected and repaired immediately to avoid accidents. Tire pressure abnormality: An exclamation mark in the middle of a bracket with a line below. This represents the tire pressure monitoring warning light. When the car's tire pressure is too low, this warning light will come on. The car's tire pressure needs to be checked and restored to the normal range.
The other day while driving, I also encountered this bulb with an exclamation mark symbol lighting up on the dashboard, and at first I thought the car was about to break down. After checking the manual, I realized it was a warning for a lighting system malfunction, most likely a burnt-out bulb. I had a friend help by pressing the brake while I got out to check, and found that the right rear tail light wasn't working. I went to the auto parts store, bought a new bulb, and replaced it myself, which solved the problem. I recommend that if you see this symbol, do a simple check first: walk around the car when locking it at night to observe the lights, paying special attention to whether the brake lights and marker lights are out. If a tail light is broken and not repaired, the car behind you may not see you clearly at night, greatly increasing the risk of a rear-end collision, and you could also be fined by traffic police. Changing a bulb yourself isn't actually difficult—there are tutorials online—but if you really don't understand, getting it done at a repair shop is also quick.
