    I would like to fit an outside light on the back of my garage c/w PIR sensor so that it only works in the dark when it senses motion, and no need for an on/off switch. Can I just tee into the wiring from the inside light in the garage?

    Yes. Just connect the permanent live, neural and earth to the corresponding wires in your ceiling rose. You’ll probably have someone come on here telling you to get a time-served electrician out to make those three connections......

    Probably get someone pointing out that the ceiling rose in the garage may not contain a permanent live...

    You might be able to tell just by looking.

    If there are two or more red or brown wires connected together but connected to nothing else they will more than likely to be permanent live.

    Post a picture ?

    No permanent live there, just switched live, neutral and earth.

    No, looks like you will have to wire it from the switch.

    Great. Is there anyway I can wire it so it only comes on when motion is detected?

    Scott - please apply a little thought.

    If the live at the light was a permanent one, how would the light ever be off?
