Is your car’s turn signal blinking at an unusually fast rate, nicknamed “hyper flash”? This can be a troubling issue, not only for you but also for other drivers on the road. Fast blinking signals can be distracting and even dangerous. Fortunately, it’s often a simple issue to fix with a relay replacement.

What Causes Hyper Flash?
Hyper flash typically occurs when you replace your incandescent turn signal bulbs with LED bulbs. LED bulbs consume less power than incandescent bulbs, so the vehicle’s electrical system detects this lower power draw and speeds up the blinking rate to compensate. The relay, which is responsible for controlling the blink rate, is tricked into thinking that there is a bulb failure.
Fixing Hyper Flash with a Relay Replacement
The solution to hyper flash is to replace the stock relay with a relay designed specifically for LED bulbs. This will provide the correct amount of resistance to the electrical system, allowing the turn signals to blink at the normal rate.
Steps to Replace the Relay:
- Locate the relay box: Usually found under the dashboard or in the engine bay.
- Identify the turn signal relay: Refer to your vehicle’s owner’s manual for the location.
- Remove the old relay: Gently pull or twist the relay out of its socket.
- Insert the new relay: Align the new relay with the socket and push it in until it clicks.
- Test the turn signals: Start your vehicle and activate the turn signals to verify if the hyper flash issue is resolved.

Choosing the Right Relay
When choosing a relay for LED bulbs, it’s essential to select the correct type and resistance value. Check the specifications of your LED bulbs and choose a relay that matches their power consumption. Using an incorrect relay can lead to other electrical issues.
Other Possible Causes of Hyper Flash
In rare cases, hyper flash may not be caused by a relay issue. Other factors that can trigger hyper flash include:
- Faulty turn signal switch
- Loose or damaged wiring
- Electrical problems in the vehicle’s computer system
If replacing the relay does not resolve the issue, it’s recommended to consult a qualified mechanic for further diagnosis.
How To Fix Hyper Flash With Relay
Conclusion
Fixing hyper flash with a relay replacement is typically a straightforward procedure that can be done in minutes. By understanding the cause and following the simple steps outlined above, you can restore your turn signals to their normal blinking rate, ensuring safe and compliant driving.
Remember, it’s essential to use the correct type of relay for your LED bulbs and to address any other potential causes if the relay replacement does not resolve the issue.
