This may seem too obvious ... Yes, of course you have a torch. But do you know where it is? If you do, could you lay your hands on it in the dark? If you are milking the cows and the lights go out do you have a lit up exit route? What about in the office?

Emergency lighting can be a great help. It kicks in only when there is a power cut. The bulkhead will light up using power from its recharged nickel-cadium batteries. The light lasts an estimated 3 Hours. 

We have one in the kitchen, one on top of the stairs and another at the end of the hall. From a safety and practical point of view they are great particularly with young children or senior citizens in the house.

In the parlour, it gives you enough light to get yourself sorted out!

These are cheap and contribute greatly to your safety during a power cut. Check out these Luceco IP65 Rated 3 Hour Maintained Bulkhead.
