Incorrect rear light colours on Wentward DT40L

A minor bug, the rear lighting on the bus is the incorrect colour according to North American (USA, Canada) regulations. All the lights pictured in red circles are Amber instead of the correct colour, Red.

 

I'm pretty sure that rear ambers are the european standard. The bus model is North American, but I assume they left it amber to be vague and have it be used in any setting.

Maybe it's an oversight though, who knows.
