2 pin flasher relay with built in resistor.
If you have upgraded to LED indicators and they flash too fast it is because there is not enough resistance in the circuit for the flasher relay (some people call them a flasher can) to operate correctly.
The choices are - add some resistors to the wiring or replace the flasher can with one that has a resistor built in!
This one has the resistor built in and will suit bikes with a 2 pin relay set up.
The picture is part of the description, so put simply if your relay does not look like this one, then it's probably not it.
If in doubt send a picture of the one you have and we'll let you know.
