This is a completed toy designed for children.
Well, it's not actually a laser...but the car will follow the light from the included light gun! Very cool! You can also control it with pushbuttons, and there's even a mode where the car will follow another car of the same series. Even more very cool! Requires 3 AAA and 2 AA batteries, not included.
Please note that the photos shown are of a prototype; the production version may vary.
