I want to make my cars turn signal flashers flash like….left, right, left, right, left, right, etc. not all at once only one side at a time. Is there some kind of flasher relay or something that can do this? What type of store could i buy it from? or is it online? or should i make my own by just using 2 different flasher relays and turning them on at different times?
What type of flasher can I use to make my signal lights flash simultaniously?
