- Not to be confused with Light Gaia.
The Light Chip is an unseen object that can be equipped to Sonic's Custom Shoes. Once obtained, it allows Sonic to use the Light Dash. It replaces the Light Speed Shoes from previous games in the Sonic the Hedgehog series and is the equivalent of Shadow's Air Chip Level Up Item from the same game. The Light Chip is required to reach Wave Ocean.
The Light Chip becomes available at the local Shop, once Sonic obtains the Custom Shoes from Alberto Robert as a reward for completing his first Town Mission, "The winder of a Shoemaker". It can then be bought for 100 Rings.
