Q. We want to remove 2 wall lights, but we do not want to permanently remove the wires, so we will use blanking plates, but are not sure how you make the wires safe first. Does anyone have suggestions please?
A. You don't say where you are. If you are in the UK you will need to use connector blocks (min 5amp rating) as we stopped using screw on type connections, such as wire nuts /midgets, many years ago. Connector blocks are widely available from diy shops.
Don't rely on turning the wall switch off to make the cables dead as there may still be live cables present. It is probably simpler for you to turn off the main switch (Usually the biggest switch at your fuseboard) After making sure that the cables are definitely dead, put the cables into your connector in exactly the same order as they were connected in the fitting. ie if a black and red cable were connected together in the fitting they must be connected together when you reconnect them. Many people make the mistake of not noting how it came apart. Put all your earth cables together and after gently tugging at all the cables to make sure it doesn't fall apart tape the connectors up before pushing back into the wall and covering with your blank plate.
You may be lucky and find that on removing the old lights you have existing connectors you can retain. In which case visually check there are no loose strands of copper after disconnecting the light and simply tape the connectors up.
If in any doubt of how to make it safe don't attempt it yourself, get someone in. Electricity kills.

Can I use an AC wall light dimmer as a 12V voltage regulator?
Q. Hi. I need to reduce the voltage of a DC power supply from 16V (external laptop battery) down to 12V so I can use it as a power supply for my other 12 volts gadgets. Can I use an AC wall light dimmer for this? I've read that this works by reducing voltage so an incandescent lamp can be dimmed. I'd like to know your thoughts if it will work for my purpose.
A. You need to learn what regulation means. You might get it to reduce the voltage but that is NOT regulating it.
