The Importance of Blinker Fluid

Hello people of the internet. I'm Nico and today I will be talking about how often your Blinker fluid needs to be changed and what cars even have them

I know this would have been more fitting for April fools day but a friend from work suggested I write about this 6 days ago (as of May 12th) and so I shall do so. I did (possibly) manage to convince one of my other friends that blinker fluid is a legit thing and now if she ever comes across this article she will understand the science and its importance. Now, grab your notepad and pencil and prepare take in this highly useful info😂.

What even is it?

Tis a fluid, obviously, since it's in the name, and it is used in your blinker, or a indicator/turn signal/flasher, depending on where you live in world. Now this may sound strange to people in the UK for instance, but people in the south, or at least in Alabama, rarely use their turn signal, if at all. So this is why they are often baffled by Blinker fluid and why they never changed it.

So for you Americans that don't know what blinker fluid is, don't worry I am here to enlighten you. Basically it is a fluid that causes your turn signal to flash in the manner it does. The exact operation varies between headlight types but if the turn signal is a halogen then the blinker fluid is injected into the bulb, where it is ignited to produce a flash of light. If it were to be continuous light then the bulb would get too hot and the act of flashing gives it enough time to cool down again.

How often do I have to refill the reservoir?

Depends of how often you use your turn signal. If you use it like the ideal law abiding citizen you may have to refill it once a year, though most Alabamians can get away with never using it. Probably even for a whole car's lifetime if they are really conservative.

Thankfully, as the turn signal is designed to flash, it only requires short squirts of blinker fluid to be injected into the bulb, making it very efficient. Now, the more bulbs are used as the turn signal the more blinker fluid is used to indicate so do please remember that before you decide not to go ahead and my some extra blinker fluid.

There are many variables when it comes to how often you need to refill but most cars, depending on how new they are, will let you know when to refill, usually when the blinker light in the gauge cluster flashes very quickly.

Isn't this just a joke?

Me? Make a joke? I would never in my life do SUCH a thing. Obviously all I stated above is completely true and definitely doesn't have countless prank videos on the internet corresponding to the subject at hand. Also, as I am a super serious, professional, motoring journalist I would never write any articles on any strange subject matters that no one would ever think about. Like I would ever write about motorcycles and cars being equally dangerous, or comparing Apple to both Ferrari and McLaren. So put quite simply...yes this is a joke, I can't help but make jokes. Whoops.

Thank you all for taking your precious time and sacrificing it to read a pointless and very dumb article by yours truly. Good luck, Godspeed, and may the Force be with you in all your endeavors!

    • I wonder if I could get away with selling it to some of my friends who don't know quite as much about cars

  • What's your blinker MPG?

    • Depending on how much time I'm sitting in traffic trying to change lanes I can go anywhere between 1000-7000 MPG. My car is typically pretty efficient since it only has one bulb for the turn signal

  • This goes against everything i learned growing up as a young driver. I understood that using your turn signal was required to keep the fluid charged, just as a car battery will die if it sits with lack of use. Each flash regenerates the photon’s positive charge slightly, keeping the fluid at full capacity. Not using it will make it degrade, much like a fine wine in an open bottle, or the way a cask strength whisky will disappear slowly if left in a glass. This is why BMWs have a much more easily accessed valve and filler for their fluid, as it rarely gets recharged, to the point of failure.

  • You also need to replace the radio filter and rearview mirror bearings while you are at it. 😁
