Why is my Subaru turn signal blinking fast?
So the strip cooled faster and cycled faster. Well, most late model Subaru vehicles use an electronic flasher relay to switch power on and off to the turn signal bulbs. The electronic flasher monitors current flow to the bulbs. If it detects less current draw, like is present when you have a burned out bulb, it will go into rapid blinking mode.
