Cars have numerous indicator lights. But what do the symbols and colors mean and how do you react when they light up?
Munich - Every driver knows them, but not everyone knows what they mean: We're talking about the indicator lights that provide information about the condition of the vehicle. They come in red, yellow/orange, green, white and blue, with each color having a different meaning. White is intended for information such as upcoming maintenance.
Blue is reserved for high beam, as “R&V Insurance” explains. The green indicator lights indicate that the respective systems, which can be switched on and off, are working and ready for use. This is the case, for example, with the turn signals, parking lights, low beams and fog lights. However, there is one exception: the indication that a light bulb is defective also flashes green and is represented by a lamp with an exclamation mark.
Indicator lights in the car: what do the symbols mean?
Yellow or orange indicator lights indicate that there is a problem that should be checked promptly. A yellow gas pump indicates that the tank is almost empty and you should go to the next gas station. A circle with three lines on the right and left indicates wear on the brake pads or too little brake fluid.
If a horseshoe-like symbol with an exclamation mark appears, the air pressure in the tire is too low and needs to be checked at the nearest gas station. However, there could also just be a problem with the calibration. If you see a car with two S's in front of the wheels, the electronic stabilization program (ESP) usually intervenes. However, if the indicator light stays on, a visit to the workshop is essential.
Indicator lights in the car: Red symbols indicate problems and functional failures
Meanwhile, red symbols indicate problems and functional failures that should be investigated immediately, explains “Allianz Direct”. This is the case, for example, with the battery, the oil level (oil can) or the coolant temperature (represented by a thermometer with waves) or if a passenger is not wearing a seatbelt. The airbag indicator light is also red, but comes on even if the airbag has been turned off.

There is also a red light for the braking system. There is now an exclamation mark in the circle and instead of three lines on the right and left there is now one solid line. If this symbol appears, you should stop immediately and call a breakdown service as there is a risk that the brakes could fail. If there is also a warning tone, it is probably just the handbrake that is still on. This symbol is also similar to the indicator light that indicates problems with the anti-lock braking system (ABS). In this case, the circle says ABS and the symbol is yellow instead of red. The check engine light can light up either red or yellow. In both cases, you should visit a workshop immediately.
