Edit to add - 14 CFR 91.175 also includes this -
"(i) The approach light system, except that the pilot may not descend below 100 feet above the touchdown zone elevation using the approach lights as a reference unless the red terminating bars or the red side row bars are also distinctly visible and identifiable."
But you are now quoting US FAA rules, OP seems to be from Europe, so is it the same in UK / EASA?
I have never read or seen this requirement anywhere, so I am curios what it is for CAA UK / EASA regulations.
