It's not a question of geography, it's survival. There's pretty much a global consensus on what light goes where on vehicles on the road. If you want to go on the road with a unique lighting system, you're risking your own and other people's lives. Pedestrians stepping from the curb will glance left, see a red light that they won't understand as a headlight, and they won't realize they are stepping out right in front of an approaching bike. Same for cars pulling out of driveways. They won't register that you are approaching at speed and they'll pull out into your path. Then you'll crash into them and blame them for being "flat earth" types.
