I've not yet tested it to see if it is a ring, if it was a spur off a spur what would the implications be just to supply a 60 watt outside light?
IMHO the work you have done would have improved the situation since you have 1 less socket to draw power from anyway and a 60Watt bulb would use next to no power in comparison to running say an electric heater from the socket you removed plus you will have a seperate fuse for the light anyway.
I'm sure however that you will be told it's a no-no so best work out if it is on a ring and post the answer so that you can be advised the way forward.
