Power Into Light Box, and From Light Box to Switch #1 and Switch #2
The following diagram illustrates the power entering the light box, and from
the light box to switch #1, and from the light box to switch #2.
Again, in this case, a larger than normal device box is required at the light, due to box fill calculations (most regular size octagon boxes will only accommodate seven wires; in this situation, you will have eight wires).

NOTE: The white wires that are being used as hot conductors need to be identified as such by the use of black tape or coloring a section of the wire near the splice with a black felt marker to indicate that it is not a neutral in this particular situation.
