This is an "upgraded" Toyota 81980-50030 flasher relay with 555 timers (one per side), so now, when the turn signal lever is lightly pressed, the flasher flashes 3 times. It's made as a “sculpture” of components inside the existing relay box. The relay is also modified so it doesn’t check for the presence of light bulbs so they can be replaced with LED ones without adding the resistors. The final schematic is made according to the available components in my handy “scrapyard” during production.
