F01 vs. F10 Turn Signal Indicators

[dbs600]

Why does the F01 7 Series have amber (yellow) rear turn signal indicators and the F10 5 Series have red ones? Can’t be a NAS vs. Euro DOT thing, as both are in the US. Strange...

I wonder that myself...

The orange LEDs are more expensive to produce. The red ones are cheaper, and BMW is pretty much screwing the US if you don't have a 7. The US is the only country in the world to allow red turn signals, and studies have shown driver response to amber turn signals are much quicker than red.

Funny... I just noticed the same thing with the current Mercedes-Benz E-Class and S-Class today; the E- has Red, while the S- has Amber! The cost savings must really add up for these companies, as I'd otherwise think world-wide economies of scale would trump; guess not!
