BTW, I just noticed how this official documentation, page 11, states that inner angel eyes are purposely made brighter than the outers. Pre-LCI. It's no wonder nothing aftermarket (even the LUX) can make them equally bright.

The daytime driving light is produced by the inner and outer corona ring. The inner chamber
of the bi-xenon headlight is used for the daytime driving light.
The inner corona ring is illuminated from behind. The reflector is designed to ensure that
the light mainly illuminates the corona ring. There is a darkened shutter in the middle of
the corona ring that blanks off the forward light from the reflector.
Light from the same headlight chamber is coupled in two fiber optics cables and fed to
the outer corona ring.
The outer corona ring functions as a light guide. The inner corona ring is brighter than the
outer corona ring in daytime driving lights mode.
