One pair red and black to com at top and L1 at bottom.
Second pair com bottom L1 top.
L2's are not used. However if switch works wrong way changing from L1 to L2 will swap which way is off and on.
The earth to terminal on backing box if there is one. If not just tape up.

I am guessing that some one has tried to connect a second lamp to the light switch rather than the ceiling rose.
There is no neutral at the light switch so one can't take a supply from the switch.
