I want to move a light switch from inside our toilet to outside, there is already a switch outside for a hall light can I use the same switch for both lights and if so which wires would I use?

So you want to switch the toilet light and the hall light together? Sounds inconvenient to me.

We can only tell you what wires to use if you tell us every wire in the box. Every box is different.
