I don't think the rear indicators are LEDs at all. They don't look like it in the photographs and now I've just read this:
"The Rear lights with lighting elements in LED technology consist of individual high-performance LED lighting elements and have the characteristic BMW "L" shape. That strengthens the rear end's identity as a BMW and makes the vehicle recognisable as a BMW even in the dark.
The large indicators and fast-acting LED brake lights also play a role in making the BMW 3 Series even safer."
If they were LED surely it would say "LED indicators"?
