Adding an inline switch?

Yep, point taken...I'd missed that, and thought that the bell wire stuff had gone long ago.
I saw a (working) glass table lamp with such cable/wire (and an unearthed brass lampholder!) only a few days ago :-)
Fairy lights.......all wired in series so if one is dud, that's it!
Quite so - particularly when more than one is dud! Mind you, even LED's tend to go out in batches of 20 or 40!

If chance gets it wrong, you switch the neutral which means that all the lights remain live whilst not illuminated (not a safe situation)
Indeed. I don't know if they exist but, if they do, a double-pole in-line switch would solve this problem for the OP.

A few of us suggested to avoid buying from e-bay so by way of explanation :

Many firms are selling stuff which they claim as genuine replacement spare parts or manufacturers genuine items, CE certified.

The reality for many of these claims is that they are copies of genuine goods (ie fakes) and are not manufactured or certified to the the same standards.

By way of example, I've just bought an aircraft seat belt extension. Whilst it looks OK, a critical engineering inspection of it shows that it is little better than scrap. Cheaply made with screws that have no threads, rough stamped metal edges, chrome plating that you can rub off with a duster etc. Mind you, it was cheap, so I got what I paid for.

So, getting back to electrical equipment, unless your e-bay seller is a genuine company selling genuine certified goods (CE or BSI marked) you are very much taking a chance on quality.

All electrical equipment for us in the UK must be CE marked. That, of course, still doesn't stop the eastern fakers from shipping in CE marked items.
 
I don't know what JohnW2 is getting at when he says that my writing that the cable is transparent shows that I have so little knowledge that I should not do this job. The cable really is transparent ~ you can see the wires within. The plug is also transparent. I can provide photos. (Yes, I really can operate a camera LOL).
I missed this one! I wasn't suggesting that your knowledge/ability was limited because you said that the cable was transparent. I fully accepted that the cable was transparent but, as has now been explained, the fact that it was transparent (i.e. not with red/black or brown/blue wires within it) meant that you probably would not have the knowledge (and/or equipment) to enable you to ascertain which wire was live/line and which was neutral.

However, now that TTC has raised some doubts, a photo of the cable and (in particular) the plug would serve to reassure us (or otherwise!) that we fully understand what you have.

Kind Regards, John

Well, I am just up to bed now, so I will take my camera with me!

Right I am in bed now, and my laptop has a card reader so I am just uploading the pics to photobucket...








 
Okey dokey....I've never seen a transparent plug!
So - it's either a remote operated switch, or a two pole switch connected into the cable.
Keep the 3 amp fuse......it makes things as safe as possible.
Bon soirée
John :)
 
The CE mark is not correct so the product is suspect.

This creates a problem with wiring up of an inline switch as you have no way of identifying the line (aka live) wire.
There is a remote possibility that the individual wires may have a coloured tracer thread in them but unless you can confirm which is the line then there is only a 50:50 chance that fitting a single pole switch will switch the line.
If chance gets it wrong, you switch the neutral which means that all the lights remain live whilst not illuminated (not a safe situation)

Surely the live wire would be the core connected to the Fuse in the plug, as it is flat twin wire it would not be hard to follow.

In most cases I think the live is also the core that terminates at the first bulb, whereas the neutral passes by right to the last bulb, usually 20 bulbs

Sometimes there is a sort of ridge moulded along the side of the plastic sheath of one core
