If you’ve upgraded your factory indicators to LEDs and suddenly noticed your blinkers flashing at double speed, you’ve encountered one of the most common issues in modern car modification ‘hyperflash’.

LED indicator lights draw significantly less current than traditional halogen globes. While that’s great for efficiency, brightness, and longevity, your vehicle’s factory flasher relay is designed to detect the electrical load of standard incandescent bulbs. When the load drops too low, the system assumes a globe has failed triggering rapid flashing.

That’s where a dedicated anti-hyperflash solution comes in.

Designed specifically for replacement low-current LED indicator lights, this unit restores proper indicator operation without the need for bulky load resistors or complicated rewiring. With an ultra-low minimum load requirement of just 0.02A, it works seamlessly with most aftermarket LED setups while maintaining a factory-style flash rate.

Not only does hyperflash look annoying, but the excessive flashing frequency can also shorten the lifespan of your indicator globes over time. Correcting the flash rate helps protect your LEDs while keeping your vehicle compliant and easier to notice on the road.

Another common issue with LED conversions is dashboard bulb-out warnings. Because the vehicle interprets the low power draw as a failed globe, some cars will constantly display a burnt bulb indicator even when everything is functioning correctly. This unit eliminates that problem by properly regulating the signal the vehicle expects to see.

Compared to traditional resistor-based fixes, a dedicated relay solution is cleaner, more reliable, and far more efficient. Resistors generate unnecessary heat and essentially waste power to mimic the original bulb load. A purpose-built anti-hyperflash relay achieves the same result without the drawbacks.

Whether you’re building a show car, modernising an older vehicle, or simply upgrading to brighter LED indicators, solving hyperflash properly is an essential part of the conversion. It keeps your indicators operating correctly, removes annoying warning lights, and ensures your new LED setup performs exactly the way it should. This easy solution from Jaycar is available here.
