On a sheet of paper:
1. Draw three parallel horizontal lines and label them as L, T1, T2 from top to bottom.
2. Draw a fourth parallel line under line T2 from the left but of half the length of the previous three and label it N.
3. Install a luminaire between the mid-point of T2 and the end of N directly under this point of T2.
4. Install a three-way switch at each end of T1 (as the common) with each switching between L and T2.
5. Observe that there are no safety violations with this scheme. It simply requires about 1 to 33% more wire.
