What does a bulb with an exclamation mark on the car dashboard indicate?
1 Answers
A bulb with an exclamation mark on the car dashboard is the lighting system fault indicator. It typically illuminates when brake lights, license plate lights, marker lights, or reverse lights are malfunctioning. The causes for this indicator appearing are: 1. Poor circuit connection; 2. Burnt or damaged bulb filament; 3. Loose wiring affecting the lighting circuit resistance value, causing the vehicle computer to misjudge. The method to eliminate this warning light is: Turn off the engine, use a wrench to remove the negative terminal of the battery, wait 15 seconds, then reconnect it - the warning light should disappear.
