I have a 98 DR350, its a dirtbike and I'm trying to make it street legal. The last thing I have to do is put turn signals. I have put the turn signals on, but do not know which type of relay to use. The signals only stay lit. My bike has just a CDI unitand a rectifier, no battery. Which type of Flasher Relay should I use? I don't know how many volts my bike is. Thanks in advance.
