Why is the position light indicator always on in the car?
2 Answers
It is normal for the position light indicator to be on in the car because the position lights and headlights are interconnected. When the headlights are turned on, the position lights also illuminate, and this is not caused by a malfunction. However, if the position light indicator remains on when the headlights are turned off or the headlight switch is in the OFF position, you should check whether there is poor contact in the headlight switch. Methods for maintaining car lights include: 1. Preventing water from entering the headlights; 2. Regularly replacing bulbs, as they are consumable items and should be replaced promptly; 3. Periodically checking whether the lights are functioning properly, and repairing any issues immediately; 4. Cleaning the lamp covers promptly when they are dirty, as dirt can affect illumination.
As a truck driver with twenty years of experience, I've seen this situation way too many times. That marker light indicator is on, most likely because you forgot to turn off the marker lights after parking. I made the same mistake last week while unloading, and the next day the battery was completely dead and couldn't start the engine. Some car designs are more thoughtful, beeping an alarm when you open the door to remind you to turn off the lights, but older models don't have this feature. If you're sure the switch is off but the lights are still on, it might be due to damp wiring causing a short circuit, especially common during the rainy season. Check it immediately—not only does it drain the battery, but other drivers can't see your car's outline clearly, which could easily lead to an accident.
