Tired of mixing up cables and turning on the switch to another line when you meant to switch on the one beside it? Well, this first-world problem is solved with these Cable Labels. As its name implies, these are labels that are meant to be attached to your cables for easy identification. Just write down what the cable connects to (for example, your TV, printer, speaker, etc.) and tack it onto the corresponding cable. Easy peasy.
The Cable Labels are available online for £7.50 (or about $12+.)
