The Start Signal is an item that only Lakitu can use at the start of every race or battle. The signal also provides the pre-race countdown. The design of the item varies depending on which Mario Kart game you're playing. This device has three lights and each one tells you when the race or battle officially begins. The signal's sequence goes from top to bottom in the first three games, then left to right since Mario Kart: Double Dash!!. If the lights are red or yellow (depending on which game you're playing), that means it's time to start your engines and when the signal turns green, that means GO! The Start Signal does not appear in Mario Kart DS, probably due to the space, processing, or graphical limitations.
