Brain & Immune System
Lights go on and off as your car checks it's systems, Lights that stay on is how your car is talking to you, letting you know a system is in need. Think about your seat belt light! (:

Newer vehicles with a tire pressure monitoring system will have this warning when your tires don't have the correct amount of air, either too much or not enough. Don't drive over any nails!
Your car's dashboard is like your Brain & Immune System
Dash lights are like synapsis in your brain telling you how your vehicle is feeling. Look at the colors of the icons on the dashboard. They're like those on a traffic light.
Your vehicle talks through lights on the dashboard know your colors!
