Outdoor light junction

I live in a rented property so I am unable to power my outdoor lights direct from the house so I intend to run an extension cable to be able to plug the lights 3 pin plug Into. when not in use though this would leave this plug outside in the weather. is there a way that I can wire the lights to a box that I could then plug the extension lead into to power the lights when I need them so that the lights 3 pin plug is not exposed all the time?

Don't do it.
Ask your Landlord or Lettings Agent to get an electrician in to fit an outdoor IP rated socket.
Running an extension lead from an indoor outlet outside is not a good idea at all.

I take it that you intend occasional outside lighting with a lead run through an open door or window, and that you intend to bring in the extension lead when you don't want the outside lights (?).
First, make sure the socket in the house is on an RCD. (It should be, but you never know!)
Then put the outdoor plug, when not in use, in a strong polythene bag sealed with a rubber band and suspend it so rain cannot run into it.

Buy a Dry Box?

Thanks fellas for the advice. I had considered a dry box as an option but just let me throw this in the mix. I have a narrowboat that has an external socket for when I moor up with shore power. Can I not use this type of socket to plug the mains into to power the lights when required?

That's a completely different question to what you asked. I don't know much about boats, but I expect it involves BS4343 type connectors and a detachable lead between a fixed supply socket on land and a weatherproof inlet connector on the boat .
Both the fixed supply socket and the inlet connector will be weather resistant to some extent when unused, unlike the plug you asked about.
If you want to use that sort of connector then the plug you are leaving outside would need to be weatherproof when disconnected.

It f it's a point for taking on shore based power than I sobtit is a socket. Appliance inlet connector yes, socket doubtful
But I know as much about boats as someone who knows nothing about them , apart from almost all the ones I have bin on/in have been under the water, under a LOT of water

Ok, I appreciate the concept is a different one but I’m trying to adapt the principle. Geoff is right with what I want to do, use an extension from the house to power the lights and disconnect when finished. This leaves the lighting plug outside so this is the reason why I ask if I could use a socket as describe. Boats/caravans use the same plug. It’s waterproof a and the extension could then be plugged into it. Do you agree?

No, because it's only waterproof or actually splashproof, when plugged in and the correct way up. When unplugged the plug is no longer waterproof. (At least the ones for my caravan aren't).

You need the ip66 version with locking ring

...and a free socket, not mountable socket of the style in that catalogue image posted by Paddler1. But the plug on the cable feeding the lights will presumably still live outside when unplugged, and that doesn't have a weatherproof cover, so storing that in a dry box would be a good idea just to stop the rain filling it up and causing the contact pins or insulating seals to degrade. Note that 60309 plug (wow, they haven't been BS4343 for donkey's years!) can still be plugged in to an industrial socket even if it's a bit damp, as worrying as that may sound, because an IP66 socket provides the necessary insulating space between conducting parts, so long as you remove as much surface water as practicable (i.e. you don't need to get the hair dryer on it first!). Plug it together before plugging in the indoor plugto energize it.
This method you suggest sounds like a good solution in your instance, since you are familiar with using them and already thinking of the importance of keeping the exposed end dry, and a plug & socket pair won't break the bank!

Thanks guys, I think I am agreeing with Dranok and going to go with the 60309 plug and connecto. Would something like this be a good solution as it has a screw cap.

Maybe, this might be better from CEF?
