This is the smallest load-independent flasher relay we've encountered yet. The m-Flash digital flasher relay is perfect for replacing conventional flasher relays when switching to LED turn signals.

This tiny relay is necessary to avoid incorrect installation of LED turn signals, ensuring your LED turn signals aren't blinking like disco lights.

  • Can be routed in the handle bar, frame tubing or in the cable harness
  • Virtually independent of load (min. 1 Watt)

    This was purchased with m-Blaze Disc LED Turn Signals . Very easy to install, very small and easy to place . They even supply resisters if you need them. This will be my go-to for future builds.

    Great product. I have purchased 3 other LED flasher relays that were suppose to do the trick and didn't. Added resisters, still not functioning. My bike is a 78 Honda CB550. This "starburst" size resister just simply does the job.
