[MiguelMarie]

A light bulb with an exclamation mark on the dashboard is the vehicle light malfunction indicator. When this warning light illuminates, it indicates that one of the vehicle's lights has malfunctioned. The owner should then inspect which specific light is faulty and proceed with repairs. Vehicle lights are extremely important for automobiles, as they include headlights, position lights, turn signals, fog lights, brake lights, and reverse lights, among others. The most commonly malfunctioning lights are the brake lights and turn signals. Brake lights are particularly crucial for safety, as they illuminate when the driver presses the brake pedal, alerting drivers behind to avoid rear-end collisions.
