[VanWalker]

Volkswagen's bulb exclamation mark warning is the bulb failure indicator, indicating that a bulb has burned out. A vehicle has various lights such as headlights, parking lights, turn signals, license plate lights, fog lights, brake lights, etc. If any of these bulbs are not functioning, the bulb failure warning light will illuminate. Below are introductions to other related warning icons with exclamation marks: 1. On the left is an icon resembling a steering wheel, and on the right is an exclamation mark, with the entire icon in red. This is the steering system warning light, indicating an issue with the steering system. 2. A triangle with an exclamation mark in the middle is the general fault indicator. This light indicates that certain components of the vehicle have issues, such as overheating of the dry dual-clutch transmission clutch, parking sensor problems, engine oil pressure sensor issues, external light problems, etc. 3. The entire symbol is yellow, featuring an irregular arc that is not closed at the top, with four small protrusions at the bottom and an exclamation mark in the middle. This symbol is the tire pressure monitoring indicator, also known as the TPMS warning light, indicating abnormal tire pressure.
