Then like this
SPUR FROM HOUSE RING FINAL > 13A Switched fused spur > SWA CABLE 2.5mm will be fine > double socket in garage > 5A Switched fused spur acting as light switch > light.
Your challenge will be glanding the SWA corectly at each end. In the garage its fairly easy if the socket is a metalclad type. At the house end you'll need either an external FCU that takes a 20mm SWA gland or a suitable external box. The WISKA boxes are also good for this.
Dont think of bending the SWA to get through the wall, SWA isnt bendy enough!
