Some 13 years ago when we started this site, we believed that the driving public had no idea what it was up against in trying to understand the warning lights and dashboard symbols being thrown at them by their car’s instrument panel.
We had no idea where this would lead.
We now host 986 (now over 1000!) of warning lights and indicators! Nine hundred and eighty six! Most are image-style indicators but there are also nearly 200 text indicators.
Every year we update the warning lights from 47 manufacturers who have or currently do sell vehicles in North America and we made the mistake of counting them last week.
If this sounds absurd to you, well we couldn’t agree more. The table below illustrates the problem.
If you count them, you’ll find 22 different images representing suspension systems. Essentially every manufacturer gets to choose an image style to use. Some include text, which is helpful, and others include a sketch of a vehicle, which is also helpful.
But note the pair that look like a hat with an arrow inside and others that don’t bear any resemblance to anything an average person can relate to!
Idiot lights, or tell-tales, as they are known only in the industry, were designed to help drivers who didn’t understand how to read a gauge and to get your attention. To those who actually did know how to read the gauges, and watched them like a hawk, the tell-tales came to be known as Idiot lights. And the term stuck.
However, in today’s vehicles, there could never be a corresponding gauge to compliment a Check Engine light, or the ABS (anti-lock brake) light for example. There actually could be a pressure gauge associated with air suspension systems represented by some of the symbols in the table. But the industry is long past gauges.
There may be 30 to 40 picture or text tell-tales on a modern instrument panel, each connected to some system in your car. We’ve counted as many as one hundred in some models! And they may illuminate in twos and threes if a problem is detected. That is, a problem with one system causes other systems that are dependent on the first to be shut off. Each of those systems will have an associated, and now illuminated, tell-tale. Today, a driver needs to be an automotive prodigy to know what’s going on.
We’ve called on the industry to trash this near useless system in the past in favor of the car actually telling a driver what’s up and what they can and can’t do. The information is in the vehicle’s computer, but is accessible only to technicians with the proper equipment.
There has been some talk of simplification, but we update the symbols in new cars every year, and when we’re done with 2024, we can assure you that another 30 to 50 symbols will be added to our pages.
We think you, the driver needs help and we are here to do just that. We ultimately hope that the way vehicles communicate with drivers is changed. In the meantime, if you are confused by the symbols that show up on your instrument panel, bookmark this site. We’ll do everything we can to help you not feel like an an “Idiot”!
