Custom Dynamics Turn Signal Flasher

Custom Dynamics Turn Signal Flashers: The LED Upgrade Your Bike Deserves

When you swap your stock incandescent turn signals for modern LEDs, the factory flasher relay often can't keep up — the lower electrical draw of LED bulbs causes the dreaded hyper-flash, where signals blink too fast or not at all. Custom Dynamics engineered a direct solution with their Electronic LED Flasher relay, purpose-built to restore correct, reliable flash rates on LED-equipped motorcycles without complex wiring or custom calibration.

Since 2002, Custom Dynamics has been helping riders see better and be seen better. The brand was founded by Dave Pribula, who leveraged his electrical engineering background and nearly two decades of experience at IBM and Philips Semiconductor to build one of the motorcycle industry's most trusted lighting brands. That engineering DNA carries directly into their turn signal flasher products.

What Makes Custom Dynamics Flashers Stand Out

The Custom Dynamics Electronic LED Flasher relay directly replaces the stock flasher relay on most metric motorcycles and is compatible with loads from 0.5A up to 10A. These units are plug-and-play on specific motorcycle models and hardwire with any other 2 or 3 pin flasher. That broad compatibility range means one compact module covers a wide spectrum of LED turn signal upgrades — from a simple single-bulb swap to a full front-and-rear conversion kit.

For riders who want more than a standard blink, Custom Dynamics also offers advanced flasher-style controllers like the Magic Strobes™ module. Designed for 2014–2021 CVO Touring models, the Magic Strobes™ Brake Light & Turn Signal Flasher applies strobe patterns to the rear LED panels, and riders can easily select from 10 flash/strobe patterns by simply spinning the dial on the module. To keep signals clear and legal, normal turn signal flash automatically overrides the brake flash/strobe when simultaneously braking and turning.

For builders who want a fully sequential look, the Sequential Turn Signal Control Module takes things further. Optimal sequential flash speed is programmable via dip switches depending on the number of LED segments desired, and the output is programmable from 2–5 LED segments — complete with a running light output control wire to shut off the running light when the turn signal sequence is activated for maximum visibility when dual-color amber/white LEDs are used. The unit is housed in a weather-tight hard case with 36" wire leads and backed by a Lifetime Warranty.

Whole-System Compatibility

If your motorcycle's flasher relay is not two-wire and/or replaceable, Custom Dynamics offers a universal load equalizer as an alternative, and for Harley-Davidson riders, a dedicated Signal Stabilizer. This ecosystem approach — where flashers, load equalizers, and signal stabilizers are designed to work together — means you're not left hunting for workarounds after your LED upgrade.

These flasher solutions are engineered to complement the full range of Custom Dynamics turn signal products, including the ProBEAM®, Genesis®, and Shark Demon® LED signal lines.
