A gorgeous set of lights to brighten the place up. These lights have multi coloured fibre optics which sparkle. The lights have also got an 8 function controller so you can change the setting from steady on to flashing ect. Led lights are very bright and energy efficient. The total length of the battery operated light set is 2m and has an extra 40cm lead wire. The lights take 3 aa batteries which ar not included. The picture only shows two colours, when the chain is seperated on this setting it would go blue/red, blue/red and then change to the other colours. You can change the setting so you have all colours showing.
