These 20m battery-operated fairy lights feature 200 LED bulbs, which are available in either white or warm white, along a green cable. The waterproof battery box boasts 4 different settings and a timer function too. Ideal for outdoor trees, bushes, hedges and decking, they're perfect for all events, including BBQs, weddings, Christmas, parties and festivals. We almost forgot...of course you can use them indoors as well! The plastic battery pack is both robust and waterproof, ensuring the batteries, function switch and timer survive all that the British weather can throw at them. Simple to use, the handy timer function allows you to leave the lights switched on; they will remain illuminated for six hours, before turning off for eighteen hours and switching back on at the same time as the previous day, it’s that easy! This is brilliant for two reasons; firstly, it saves you having to remember to switch your beautiful lights on/off every night and, secondly, it conserves the battery
