    If you are referring to the requirements for operation below the DA/DH or MDA, ten items are listed in 91.175 (c)(3), but (vii) and (ix) each have two items listed and (i) has the addition of red terminating bars or red side row bars to enable continued descent below 100 feet DH/MDH:

     

    (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.
    (ii) The threshold.
    (iii) The threshold markings.
    (iv) The threshold lights.
    (v) The runway end identifier lights.
    (vi) The visual approach slope indicator.
    (vii) The touchdown zone or touchdown zone markings.
    (viii) The touchdown zone lights.
    (ix) The runway or runway markings.
    (x) The runway lights.

    Just to clarify in my head since I don’t read FAR legalese very well. If at MDA/DA and you can’t see any of the references listed in 91-175 (c)(3) i-x, you must go missed. However, if you get to the MDA/DA and CAN make out the approach lighting system, then and only then, you may continue your decent to 100ft above the TDZE. If at that point, you can make out any of ii-x, you have “runway environment” and can legally land. If not, you must go missed. Am I interpreting that correctly?
