A stop or indicator lamp is normally 21w
21w/12v= just shy of 2A circuit current.
A lot of led lamps will not stand that current through them so connecting a resistor in parallel so that it shunts the led lamps but gives a circuit current of 2A will work. Problem is the current will try to take the path of least resistance so the led lamps may suffer either way.
I have never measured the resistance of an led, reverse polarity they are open circuit correct polarity no idea.
