This will fit your super soco TS/TSX blinkers in case you want to remove the stock license plate and blinker holder(the rat tail). If you havent removed it, this will be impossible. If you keep your rat tail, you should put a redundant zip-tie from the license plate to the rat tail, because it will break(the metal you screw the plate into).
It is supposed to be mounted underneath the seat with the 2 screw holes which were previously used to keep the "rat tail" in place. Keep in mind this compromises the waterproof-nes of the connectors underneath the seat.
You may need to buy a separate light for the license plate depending on where you live.
I printed it with PETG with 60% infill but that is crazy overkill, would work with 30-40%, maybe even 20%
