Indicator Blinks Too Fast
Step 3 of 4
"Your blinkers are in turbo mode. Looks funny, but it's not a joke."
The Hyperactive Blinker
This often means one of the bulbs is out, causing a drop in total resistance — flasher relay speeds up as a result.
The flasher relay is designed to blink faster when it detects a lower resistance in the circuit. This is actually a built-in warning system to alert you that a bulb needs replacement.

🎙️ Listen to Explanation
🛠️ Diagnostic Steps:
- Check all bulbs visually
- Replace missing/dead bulb
- Watch flasher timing restore
In this lesson, you'll learn:
- Why indicators blink faster when a bulb is out
- How to diagnose which bulb needs replacement
- How flasher relays work
- The relationship between resistance and blink rate
