Installing aftermarket LED turn signals or an LED integrated tail light can cause your turn signal flash rate to increase dramatically, or even sometimes cause them to not function properly at all. This plug-and-play LED Flasher Relay is your solution. No custom wiring involved, simply unplug your OEM relay, and install the TST LED Flasher Relay.
Applications: Please refer to the Applications table at below for a full list of compatible models.
Only ONE relay is needed per motorcycle regardless of front and rear signal set-up.
Features:
Slows turn signal flash rate down to an adjustable 85 cycles per minute when turn signals are experiencing hyperflash or stay on continuously
Adjustable turn signal flash rate enables you to speed up or slow down the flash rate to fit your preference
Plug and play installation meaning no cutting, splicing, or soldering
Replaces the stock relay and fits like OEM No need for cumbersome and heat-generating load balancing resistors
Flexible relay housing enables easy access to the flash rate adjustment dial inside of the relay unit
Wide range of compatible models from KTM, BMW, Ducati, and Suzuki - be sure to check the Applications tab specific model compatibility
Our Gen2-SK LED Flasher Relay works with the following signal configurations:
- All stock
- Stock taillight, aftermarket signals
- Integrated taillight, stock signals
- Integrated taillight, aftermarket signals
If you just installed aftermarket LED turn signals or an LED integrated tail light and your turn signals are flashing way too fast, or perhaps simply staying on completely, you're at the right place to find the solution! Our TST Gen2-SK LED Flasher Relay fits a wide range of models from KTM, BMW, Ducati, and Suzuki to fix what we call "hyperflash". It slows the flash rate down to a pre-set 85 cycles per minute but can be sped up or slowed down using the adjustment dial located within the unit so you can get the exact speed you are looking for. The plug-and-play installation means that you don't need to splice in any load balancing resistors that generate unnecessary heat and require splicing into your stock wires. Simply remove the stock relay and install your new TST relay and your wiring job is done. It's that simple!
INTERNATIONAL BUYERS: Please make sure your bike uses a 2-pin relay for the signaling system. If your bike has hazard lights it may need the 4-pin relay. Please also note the pin configuration and make sure it matches what is on your bike. IT IS YOUR RESPONSIBILITY TO VERIFY FITMENT BEFORE MAKING YOUR PURCHASE. If you happen to have a 4-pin relay, there is a chance the relay found HERE will work for you. Again, it is your responsibility to verify fitment before making final purchase.
This LED flasher relay should NOT be used in conjunction with load balancing resistors.
