hmm, i figured JOM would be similar to the brand I have, but it seems like you were provided 2 resistors/regulators for each outer tail light? so in total you have 4 pieces of the tail lights, 2 inner, 2 outer, with 2 resistors/regulators for each outer light, and 1 resistor/regulator for each inner light for a total of 6 resistors/regulators?

either way, you re-use your stock bulbs housing. it's easily popped off of each outer light
