Why Is My Signal Light Blinking Fast?

If you’re driving on the Plymouth roads and find that your turn signal light is blinking faster than usual, it’s usually related to an issue with your taillight or signal connection. This usually isn’t a serious problem, and it can be easily fixed by the service team at Morrie's Minnetonka Mazda. However, it’s important that you address it sooner rather than later, so it doesn’t turn into a more significant problem.

WHY YOUR TURN SIGNAL IS BLINKING FAST

When you switch on your turn signal by moving the signal arm up or down, you activate something called a signal circuit, which powers the lights on the back of your car. The circuit’s current relies on the load demand or the bulbs. The signal circuit has predefined calculations for the current resistance and voltage, so if anything changes in those variables, it can make the blinker go faster than usual. Here are some of the most common causes for a signal light blinking fast:

Bulb needs to be replaced
Bad ground connection
Weak voltage
Loose or damaged connections

WHY DO MY TURN SIGNALS BLINK FAST WITH LED LIGHTS?

These days, more and more vehicles come with LED signal lights compared to older incandescent lights. If you drive a vehicle with LED lights and find that they’re blinking faster than usual, it’s called “hyper-flashing” and can be reduced by installing a resistor or relay. Here are three easy solutions to reduce flashing in LED signal lights:

Fitting a new turn signal relay or replacing an existing relay
Installing load resistors that copy the original load demand
Choosing LEDs with a decoder and resistor already built in
