Well, this could be due to a couple of different things. First off, you must make sure that you have the wires hooked up correctly (meaning these only come with 2 wires and your bike's stock lights may have come with 3 wires......if this is the case then you need to make sure that the running-light-wire isn't connected and that the signal and ground wires are connected to the new LED signals instead...... if you have the running light wire connected then the signals will always be solid, so you can simply disregard the running-wire and leave it discontinued). Secondly, if the wires are hooked up correctly and they still light up but don't flash, then you will need to get an LED flasher relay to essentially slow down the flash (this acts as a resistor and limits the rate of flash for the LED turn signals).
