If I understood it correctly :
Engine Off = white/transparent
Normally dim lights (front) are on in Belgium when the engine is running including the red tail lights (inner 2).
Breaking in the EU will only activate the inner 2 taillights.
The outer ones are reserved for the orange turning signals.
The famous RED mustang Tri-Bar is gone....
even when lights are on.
I would expect all should be RED in ON mode and when turning the outer ones turn into orange...
These are LEDs and can have all colors. Many brands (audi, BMW are full red)
Let's see what happen and let's hope this is the Asian version ! (taillights look like 2x3 standing up rice grains anyway)
