red LED is flashing all 5 Seconds

[Andreas_HGW]

Hello

I'm using Magic Lantern at a 5 D Mark 3 (ML Version 1.2.3)
I'm new here and I have 3 questions:

1.
My red LED is flashing all 5 seconds even if I do not use the camera.
Is this normal? Can I disable it ?

2.
If I use the MLV format all Overlay's (Magic Zoom...) disappear while recording.
Is there any way to see the Overlay's even while recording?
If I do not use MLV recording then I can see the Overlays while recording.

3.
In all videos about Magic Lantern at youtube I can see a multi color (green, yellow, red,blue) last line with the values for Av,Tv,Iso ...
At my camera the color for this values are not so colorful and I did not find any possibility to change it.
