When you change your bike's stock incandescent signal lights to LEDs, you have to install resistors or you get "hyper flash"... that annoying super fast signal flashing. Adding resistors can be annoying so thankfully there is another option!
You can swap your bike's flasher relay out and replace it with a flasher specifically made for use with LED signals. The install is quicker and easier than adding resistors to four signal lights and its cheaper too!
