This circuit made from three 12V
DPDT PCB (printed circuit board) relays turns your rear turn
signals into additional brake lights while allowing them to
still function as brake lights.
I soldered wire to the
appropriate relay pins, put pieces of popsicle stick between
them, wrapped them in electrical tape and then filled the
tape with epoxy to hold them together and waterprofo them.
