Hi just wondering if anyone can help. Im changing an old 2 switch light socket in room for a new one but cant get both lights to work. There are 2 grey cables each with a red, earth and black wire in. I have tried RED to COM, BLACK to L1 - only 1 light then works. RED to COM, both BLACKS in same L1 - 1 light works. I have used a loop wire as well but light then doesnt switch off. Please can anyone help?

This is two switches on one plate I assume and no other switches control the lights concerned. And assuming it is a normal wiring set up
If so there will be two commons (one for each switch) and two L1s ( one for each switch .
The reds go to commons and the blacks to the L1s.

Do both lights come onIf you connect the red to its own black (using a term block eg) ?

I tried RED to COM, BLACK to L1 with both cables, didnt work. I have now wired : CABLE 1 RED to COM BLACK to L1
CABLE 2 RED to L1 BLACK taped off
and linked the two COMs together with RED link wire. Does this sound ok, it makes both lights work but is it safe?

Put that spare black in a bit of choc block. Tape can come unstuck over time. If it works, wonderful!
Thanks for all replies, now sorted.
