Colour Phasing Mode For some cool mood lighting, set the Pac-Man Ghost Light to its colour phasing mode where it will cycle through 16 different colours. The colourful LED light is inspired by the 8-bit style found in the original Pac-Man games.	Party Mode Turn up your music with party mode on to see the ghost flash in time with your beat. There’s no need to plug the light into your phone or stereo, the sound reactive light will automatically respond to music. Change how the light reacts by adjusting the sound sensitivity dial.	USB Powered Power up the light by plugging in the included USB cord into any USB port whether that’s your laptop, gaming console, power bank, or your own USB adapter (adapter not included).
