BKS's "US" version is the Euro version but no rear fog.
When BKS says "US Version" they probably mean the wiring (harness). This is the same with Audiamant. The tails are still the Euro tails.
The US FL tails are visually different than the Euro ones, not just in terms of wiring. There was a discussion about this on the Vortex forums and someone had uploaded an image.
