Converting two way light to one way and add a light

[Tyre Smoke]

Sorry for the heavy title.

Currently I have an outside floodlight that is switched from inside the house and outside via a weatherproof switch on the gatepost. The switch on the gatepost never gets used, so I am trying to get my head around whether it would be simple enough using the existing wiring to substitute the gate switch for a lamp?

The switch on the gate has three wires going to it, red in COM, blue and yellow into L1 and L2, all sleeved with red (to show live). this corresponds with the indoor switch which has red into COM (presumably this is the feed from the supply) and yellow and blue (sleeved red again) in L1 and L2.

The indoor switch is part of a three gang switch, but as far as I can make out, the wiring diagram is like this:

So, am I right in thinking that if I remove the switch on the gate I can substitute a lamp by moving some wires to complete the circuit and if so, which to where?

I see, but surely the live to the gate which is switched there can be made part of the circuit I.e live in and the wire to the existing lamp can be neutral out, completing the circuit? It would effectively make the wire between the two L2 terminals redundant, or actually used as earth?

Sorted it! Many thanks for your help. A bit of further investigation and it would seem there has been a bit of bodging in the past with a junction box filled with silicon sealant amongst other things.
