Your both wrong There are 2 kinds of reflector lights: Symmetrical and asymmetrical ones.
JDM/ADM cars have ASYMMETRICAL lights while USDM cars have SYMMETRICAL lights
The DEPO light you bought from the America are symmetrical lights and can be used in both
LHD and RHD countries without any adjustment since the light pattern doesn't tilt to either left or right like a asymmetrical lights would do.
Here you have asymmetrical headlights see how they tilt to the right? If you where to drive in Australia with these lights you would blind everyone from Sidney to Mars. however if you mirrored this image you would get the lightpattern of an aussie/japp car with asymmetrical headlights
Here you have symmetrical headlight, as you see it doesnt tilt to either side thus they
cant blind oncomming drivers in RHD countries. Thats why an american can import a old Austin Mini without needing a headlight convertion since these cars have symmetrical lights.
Bottom line is that asymmetrical lights are LHD and RHD spesiffic and symetrical lights are not. Thats what im talking about.
