SRS Airbag System & How It Works

So exactly how seat belt warning light works?

If you own a modern or relatively modern car, you’ve likely experienced the seat belt warning light and the ding that accompanies it at least once or twice (and probably a lot more!). However, you probably have never delved into how it can do so. Below I will describe just that for you!

The seat belt warning light is a very important and helpful tool. Sometimes, we speak on the phone or to our passengers, or we crank up the music pretty high. With those vocal distractions, it is sometimes hard to hear the ding of the seat belt as it reminds us to buckle in. That is why the seat belt warning light is so beneficial. It is likely that if we don’t happen to hear the seat belt sound over whatever is muffling it, we’ll at least see the glow of the seat belt light on our dashboard.

Now let’s get down to what happens to initiate the seat belt warning light flashes. Inside the driver’s seat belt buckle in all vehicles, there is a switch that is triggered when the seat belt is fastened and unfastened. The car’s computer system monitors this switch and can tell when the driver has not secured his or her seat belt.

An important thing to note is that when an engine is started, the seat belt light usually flashes for a second or two (even if the seat belt is already secured). However, after those few seconds, the light immediately disappears. If the driver and/or front-seat passenger is secured into their seat belt, the light should stay off.

There are times when the seatbelt switch can get broken or get stuck—which will result in a light that does not turn off. In that case, the buckle needs to be cleaned out or replaced, and everything should return to the way it should be. You can turn to the company Safety Restore if you do have this issue, or any other issue with your seat belts. The company provides quality seat belt repairs at a reasonable price point.
