Left out the side clip so it would have a cleaner flush look. For the American standard all the light bulb sockets are the same except for one. Looks like a 194 bulb socket for the J-spec. If you leave this bulb out only half of the red will light up. Instead of changing the bulb socket to the J-spec, I modded the tabs on the OEM socket to make it work.
J-Spec vs. US OEM. The J-Spec has the larger clear reverse light lens. Another difference is the built in reflector is vertical vs the US which is horizontal. The J-specs have a sharp outline dividing up turn , stop, and reverse lights.
