Diode Dynamics LED Turn Signal Flasher

 

Diode Dynamics LED Turn Signal Flasher is a direct replacement relay option for compatible vehicles that hyperblink after LED turn signal bulbs are installed. It is designed for customers whose vehicle uses a replaceable flasher module and needs a cleaner correction method than adding load resistors.

When incandescent turn signal bulbs are replaced with lower-draw LEDs, many vehicles sense the reduced load as a burned-out bulb and respond by flashing quickly. A compatible LED flasher relay restores normal blinking behavior by replacing the original relay with an LED-friendly module.

This group includes several relay styles across a wide range of vehicles, including CF18, EP26, EP27, EP28, EP29, LM470, LM487, LM526, and CF15-style configurations. Terminal counts vary by configuration, so relay style and vehicle compatibility must be matched before installation.

The product is focused on turn signal correction, not brightness or color output. It supports compatible LED bulb upgrades by addressing the vehicle-side flash rate issue that can appear after the lower-current bulbs are installed.

Installation is typically a simple relay swap when the factory flasher is accessible and replaceable. Customers should confirm the vehicle uses a replaceable module, match the relay style, and test turn signals and hazards after installation.

Whether customers are upgrading for LED turn signal upgrades, hyperflash correction, or direct relay replacement, the Diode Dynamics LED Turn Signal Flasher delivers a focused lighting solution with clean integration and confident everyday usability. Now Available at LEER! The upgrade is especially useful for customers who want a finished result that looks intentional rather than improvised. Its compact, application-matched design helps the finished installation blend naturally with the vehicle. The result is a practical electrical or lighting upgrade that supports a cleaner final build.
