Runway and Taxi Lights (Low Visibility)

[GAMEOVER]

Well, hi matesĦĦ

I know that the Runway Lighting changes the last 3000 ft of the runway:

1. - At 3000 ft remaining, the white R.C.L begin to alternate with the red for the next 2000 ft
2. - At 2000 ft remaining, the white R.E.L begin to change from white to yellow for the rest of the runway.
3. - At 1000 ft remaining, the R.C.L changes to all red.

Also, Taxi Lights consist of:

1. One line of green taxiway centerline lights and two lines of blue taxiway edge lights.
2. And, at certain points on the taxiway there might be red stop bars.

Is there anyone that can explain the difference between Runway and Taxi Lights in Low Visibility?

I know that the separation of Center Lights must be 15m for ILS CAT III and 30m for ILS CAT II. Is it correct?

Anything else please?
