   • b

     on the same post below the first Stop signal or the last Stopsignal.

4. 4When placed in accordance with clause (b) of sub-rule (3), the variable light of the Stop signal shall take the place of the fixed green light of the Warner signal and the mechanical arrangement shall be such that the Warner signal cannot be taken ‘off’ while the Stop signal above it is ‘on’.
