Why Car Windows Have Little Black Dots

  • Published on Nov 14, 2019
  • Every now and then, you get stuck in traffic. So what do you do? You stare blankly at your windshield, right. And you probably notice the little black dots around the edges. Ever wondered what those are for?
    But black dots aren’t the only part of your car that might have you wondering, “What on Earth is that for?” Since you’re still looking at your windshield, did you notice that little line with an arrow pointing down and AS1 written on it? Or what about the black lines going across the back window and that little snowflake on your dashboard? Let's figure out!

    - The dots come out of the black band that goes around the window. That band is called the frit. It's the ceramic paint that protects the sealant holding your windshield in place.
    - They make a nice gradient transition from the black frit to the clear window. This gradient is also a safety feature.
    - The black dots are there to even out the heat and minimize optical distortion. Without them, the windshield would deform.
    - Those black dots above the rearview mirror have another important function: they help protect your eyes from the sun while you're driving.
    - AS1 means that the glass should let in no less than 75% of the light. The line and arrow mean “from this point and downward.” S
    - Have you ever noticed a little snowflake light up on your dashboard? This is the Frost or Freeze Warning, and it lights up automatically to inform you that the temperature outside has dropped so much that the roads are likely to freeze.
    - Gas tank locator tells you which side the tank is on! By the way, there are no strict regulations as to which side the tank should be on.
    - Drowsiness detector does exactly what it says: if the car “feels” that you’ve been on the road for too long or you keep slowly drifting out of your lane, then this indicator will come on.
    - When sensors decide your vehicle is about to spin out or isn't turning far enough, a little skidding car icon lights up on the dashboard.
    - The original purpose of ceiling handles was to help you get in and out of the car.
    - In most mini-vans and some crossover SUVs, you can pull down a convex mirror from a special compartment in front of your rearview mirror. It helps you keep an eye on the kids, pets, or just passengers in the back seats without taking your eyes off the road for a second longer than needed.

    The fuel door side is also depends on which side the exhaust system runs. If you ever notice in the rear of the vehicle what side the exhaust pipe or muffler (if it's single exhaust) is on, the fuel fill door is on the opposite side of it. On dual exhaust vehicles it could be on either side. Also most of the time most brands use one side for fuel doors on most of their models, an example would be Toyota has the fuel door on the drivers side.

    44 seconds in and I have all the info i need.
    The dots are called the frit and they protect the adhesive that holds the windshield in from the sun's rays.
    Also, who doesn't know what a rear defroster is?

  • Holly Y

    Ford cars have black lines on the front windscreen, very thin but visible. Also for defrosting. So much better than air vents

  • Jorge DSM
    Jorge DSM 18 days ago

    I thought the lines were a wired circuit which when the glass was broken it also breaks the circuit and sets off an alarm in case someone tries to break into your car. I thought this for all my life until now.

    Gas tank fill openings are always on the opposite side from the exhaust. It has been a U.S. Federal regulation for many years.

    • Pirate Labs
      Pirate Labs 13 days ago

      @Rosa Amarillo Well, dual exhausts do not fit into the regulation. Most factory "dual exhausts" are actually a single exhaust that only empties into twin outlets in the back. Some are real though and I am not sure how this works unless there is a waiver for those. If you look at all of the singles though, you will see the gas fill on the opposite side.

    Having that convex mirror to see the back seats its not a great idea really, its a distraction, if ya needa see whats going on elsewhere in the car ya needa pull over.

    Speaking of front window defrosters, I saw the coolest thing on this Focus Diesel I rented in Europe. It had virtually invisible lines running through it for defrosting. Works the same as the rear, but without having to blast the heat. Probably does a better job from a cold start as well. I haven't seen that before on other cars, but will definitely keep an eye out for that feature on the spec sheet next time we're buying.

  • Mark Sandstrom
    Mark Sandstrom 20 days ago

    I have a theory about gas cap sidedness - that it tends to relate to the home country of the manufacturer, whether that place drives on the right or the left. There is (maybe?) somewhat greater tendency for more-dangerous side-swiping accidents to occur on the driver's side of a car whichever it is, so that is a not-as-good side to locate the gas cap. Japan has RHD at home, and generally Japanese cars have left side gas caps. Germany has LHD at home, and German cars generally right side gas caps. On the other hand, reengineering a vehicle to move its gas filler for export markets is expensive and of little other benefit. I know this theory doesn't explain all cases - 2 Mazdas and 1 Subaru I've owned all violate the theory. But my several Hondas and VWs have all fit it.
