What does the bulb symbol on the car dashboard mean?

The bulb symbol on the car dashboard is the bulb failure indicator light. If the license plate light, width indicator light, reverse light, etc. are damaged, this warning light will illuminate. Below is an introduction to the car dashboard: Introduction: The car dashboard is a device that reflects the working conditions of various vehicle systems. Different cars have different dashboards. However, conventional dashboards in most cars include a speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. Beneath the surface of modern car dashboards, various indicator or warning lights are installed, such as the coolant level warning light, fuel level indicator, washer fluid level indicator, charging indicator, high/low beam indicator, transmission gear indicator, anti-lock braking system (ABS) indicator, traction control indicator, airbag (SRS) warning light, etc. Tachometer: It is generally located within the instrument panel, placed symmetrically with the speedometer. The tachometer operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted. It converts these signals into a displayable RPM value. The faster the engine speed, the more pulses the ignition coil generates, and the higher the RPM value displayed on the gauge. Most modern cars use electronic tachometers, which come in analog (pointer) and digital (LCD) display types.
I was a new driver and used to feel nervous about the various symbols on the dashboard. Recently, I encountered a bulb-shaped indicator light that turned on. After checking online, I learned it indicates a fault in the external lighting system, most likely a malfunctioning headlight or taillight. When it lights up, it means the lights may not be working, directly affecting nighttime driving safety. If you can't see the road clearly or the car behind you doesn't notice your taillights, the risk of accidents increases significantly. After parking, I first check which light isn't working and try to see if the fuse is blown—usually, the fuse box is under the steering wheel, and replacing it yourself is quite simple. But if the light is truly broken, don’t try to save money; get it fixed immediately. Remember, safety comes first. I make it a habit to spend a few minutes each month checking my car lights. Developing good habits can prevent problems, so don’t underestimate this indicator.
