  • Maintains OEM Blinker flash rate for a wide range of LED and non-LED blinkers.
  • Plug and play connectivity with OEM fitment (see compatibility list).
  • Recommended accessory for Custom LED Integrated LED Tail Lights.
  • Near zero initial turn-on delay (other LED relays delay when signals are first engaged).
  • 1-year Warranty & Satisfaction Guarantee.
  • Ships same business day.


Now you can finally fix the flash rate on your Suzuki motorcycle with our unique Plug And Play solution!  That's right, our Electronic LED Flasher relay directly replaces the stock combination relay on some Suzuki motorcycles by plugging directly into the harness in place of the OEM flasher relay!  All functions of the OEM combination relay are supported, with a normal blink rate for the flasher relay function.  See the compatibility list for details.  

For other motorcycles not on this compatibility list, please click here.

This unit is guaranteed to operate at the normal DOT blink with stock blinkers, LED blinkers, or any combination of both, provided the total load on the system is within 0.05A to 10A (0.6 Watts to 120 Watts!) - which basically covers the majority of  blinker products on the market!

See the Installation Tab for more important details.

Your motorcycle must have a rectified standard 12VDC system for this flasher relay to work (most bikes are 12VDC).


  • Minimum Rated Current: 0.05A
  • Maximum Rated Current: 10A
  • Rated Voltage: 12VDC
  • Flash Rate: Constant
  • Size: 1.2" x 1.77" x 0.74"

Compatibility List



This list will determine if your motorcycle harness is known to be Plug-And-Play with our ELFR-1-U Flasher Relay!  If your bike is not on the list, it may or may not be plug-and-play.  Please visually compare the flasher relay connector on your motorcycle to confirm before ordering.  The compatibility list is arranged by engine displacement.  If there is no year designation for your bike, that means it fits all years.

The Custom LED ELFR-1 Plug-And-Play Electronic LED Flasher Relay comes with detailed installation instructions.

Installation of this product requires that you identify and remove the OEM flasher relay motorcycle.  If you are unfamiliar with the location of your OEM flasher relay, or electronics in general, please consult a qualified technician or your repair manual for additional information.

Installation of the ELFR-1 is as follows:

NOTE: In some rare instances, when there are NO incandescent loads on the blinker system (LEDs front and rear), additional actions or components may also be required to prevent a wide range of blinker problems.  These problems are all associated with a lack of resistive load on an all-LED blinker system that was designed for incandescent lamps.  Problems such as, but not limited to: the 4-way blink problem (both sides blinking at the same time), the no-blink problem, and Integrated LED Tail Lights staying in "blinker mode" due to non-zero blinker voltages.  Rest assured that Custom LED has the knowledge, experience, and expertise to tackle any issues that may arise on your motorcycle.  

Remember, the Flasher Relay ONLY controls the speed of the blinkers on the motorcycle, and any other problems that arise are independent of the flasher relay, and are resolved separately as well.

LED Flasher

Great quality. Easy installation. Makes my LED turn signals work like magic.

Christopher M. verified customer review of Blinker Genie - for Motorcycles (pair)

Doesn't get much easier.

2005 Boulevard C50, installation took 5 minutes, and solved all my hyperflash issues. Remove the side cover, pull the existing relay, replace with the ELFR-1-U, replace side cover, fire it up! Beautiful.

It works better than TST one but still some problems

This is a review for the 7-pin LED relay unit that fits Suzuki motorcycles. I previously tried the similar produce from TST Industries, which did not work correctly. It did not flash at all, leading me to believe there was not enough load on the turn-signal circuit. I wanted to get these working: https://www.amazon.com/gp/product/B07KBXYBQG/ref=ppx_yo_dt_b_asin_image_o03_s00?ie=UTF8&psc=1 They are sequential (animated) LED signal lights / running lights combo. The are supposed to function as white or red running lights, and then switch to animated amber signals for turning. They did seem to work for a few minutes after I installed the CustomLED flasher, but then for some reason the running light circuit is over-riding the turn signals. I can have them running as running lights, or turn-signals, but not both. Actually I'm not sure if this is an issue with the flasher or the turn signals.

Hello Efrem, thank you for your 5-Star review! The flasher relay on a motorcycle ONLY controls the speed of the blinkers. From your review, it appears that our ELFR-1-U has solved your blink speed issues, and is now allowing the signals to complete the sequential sequence when turning. As for the running light function interfering with the turn signals, this can be either an issue with the aftermarket lamps themselves, OR your motorcycle may be experiencing floating voltage on the turn signal circuit because of a lack of restive load. I'd like to help you troubleshoot this installation if you still need assistance. Please reply to this message, and we can get a dialogue going.


Perfect product!

Took the hyper flasher right out of my 2019 Suzuki sv650x after installing LED's. Plug and play, too easy! And great customer service from Jon!

Works great

It really does the job easy to install couldn’t be happier!

Expensive but worth it. So far so good.

I bought this relay for my SV650 to slow down the blink and accommodate my aftermarket LED flashers I had installed. I tried a cheap eBay relay which worked fine, but it started on an off-blink. This one starts with the on part of the blink, just like the stock setup. No comment on longevity yet but the general look and feel of the relay is encouraging. Four stars only because I have no longevity data and $25 is kind of steep for a little relay. Made in America though!

Hello Charlie, thank you for your 4-Star review! You will be pleased to learn that our product is backed by a 1-Year warranty, so you can put your longevity fears to bed right there :) As for the cost, this device is more than just a flasher relay. It supports other critical functions on the motorcycle, all in one unit. This is why it is a 7-pin device, and not 2-pin. Would you consider revising your review to 5-Stars with this new information? Please let me know :) We work very hard on our products here at Custom LED.


Love the product!

Finally a plug-and-play solution for Suzuki that actually works! As many of you Suzuki owners know, this module is more than just a flasher relay. There are several functions combined into this single relay - hence the 7- pin connection. Some of these functions are critical functions like the side-stand safety switch and neutral safety switch. I wouldn't trust these critical functions to just any relay that claims to be compatible. Custom LED always delivers trustworthy products backed by excellent customer service! Don't hesitate to purchase this item from Custom LED. They have been in business since 2003 and have achieved an exemplary reputation in the motorcycle industry.
