The Most Common Car Warning Lights Explained

A vehicle’s dashboard warning lights are nothing new, but the variety and number of messages they relay have increased significantly, especially on newer vehicles. Not all warning lights are universal, either – they can vary widely by model and make, especially in foreign-made cars and trucks or high-end vehicles with more exotic systems. Keeping the owner’s manual handy will make it easier to decipher seldom seen or unknown warning symbols.

While warning lights indicate that a fault has occurred inside the vehicle’s system, few of them pinpoint the exact component or system that has failed. At Autologic in Fort Lauderdale, our automotive specialists use the latest diagnostic technology to determine exactly what and where the problem is on any type of domestic or foreign vehicle.

  • Warning lights also vary in color in order to indicate the seriousness of a mechanical or system problem. A red warning light indicates either a potentially serious problem or safety issue, which should be attended to immediately by a professional. However, a red light might also serve as a reminder to the driver about service maintenance.
  • When a yellow or orange light activates, it’s usually a signal that a component needs servicing or repair. If the light flashes, it’s important to contact a repair shop or dealership.
  • Green and/or blue dashboard lights only serve to let the driver know that a system is active and operating.

The following list of warning lights contains some of the more serious alerts used by auto manufacturers. If any of these symbols light up, take no chances – stop the vehicle immediately and contact an authorized repair shop.

  • Brake warning light: Usually in red text, it indicates a serious problem with the main or emergency brakes.
  • Temperature warning light: If the symbol (a thermometer sitting in water) is red, it indicates an overheated engine. If the light is blue, it means the coolant temperature is too low. Blinking from red to blue signals an electrical wiring malfunction.
  • Oil warning light identifiable by an oil can symbol, a red dripping oil can indicate low pressure; if underscored by wavy lines, it means the oil level is low.  The text symbol “Oil Level”, used by some manufacturers, indicates the oil level or engine needs to be checked.
  • Charging system warning light: The appearance of a bright red battery symbol means either a bad battery or a failing alternator. In either case, the vehicle will not be running for long. Stop the vehicle and immediately contact roadside assistance.
