Bottom line

Car warning lights vary by colour to indicate the severity of a mechanical or system issue.

  • Red warning Light: The issue is very serious and should be attended to by a certified professional. Red light also reminds you of an upcoming car maintenance.
  • Yellow/Orange Light: It means a component needs servicing or repair. If it’s flashing treat it with urgency.
  • Green and Blue Light: This serves as a reminder that the system is actively operation well.

Not all dashboard symbols and car warning lights are universal; they vary by the car’s model or make. Some cars and trucks or high-end vehicles are fitted with more exotic systems.

Over time and with the increase in newer vehicle models, the number of car light symbols keeps increasing.

So it’s advisable to keep your owner’s manual within easy reach to help you decipher these warning signs.

Or an even better idea: just use GOFAR to get alerts on all your car issues in plain English.
