Turn Signal Lever


What does it mean when your turn signal blinks quickly? A broken taillight, a bad connection, or other issues could be present. If you’re wondering “Why is my turn signal blinking fast?” you’ve come to the right place. We’ll go over possible reasons and solutions for each, below. If your turn signal is blinking fast our service center here at Nyle Maxwell Chrysler Dodge Jeep Ram of Castroville can help.

Why Your Turn Signal is Blinking Faster Than Normal

Turn signal lights need a signal circuit, which is utilized when you use your turn signals. The signal circuit’s current needs the correct load demand from the bulbs. Putting it simply, the turn signals rely on very specific current, resistance, and voltage. If any of these change, the blinker cadence can be thrown off. Here are some common causes for a signal light blinking fast for San Antonio and Alamo Heights drivers:

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

Why Do My Turn Signals Blink Fast with LED Lights?

If you’ve installed LED lights on an older car that didn’t originally have them, and the blinkers flash much faster than normal, this is called hyper-flashing. Generally speaking, what causes this is a lack of compatibility between the LED lights and the analog systems of older cars. There are several possible solutions to this problem:

  • 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.
