Kids are going to absolutely love these light-up track cars! This 3-pack comes with blue, red, and green cars that each feature FIVE bright LED lights that flash and glow. Just press the button on top and the cars light up with colorful patterns - they look amazing in the dark and make track racing even more exciting. These are designed to be compatible with most glow-in-the-dark race track sets (just make sure the track inner width is at least 2.2 inches for smooth operation). Each car requires 2 AA batteries (not included, so you'll want to grab some rechargeable ones!), and they come with a small screwdriver for easy battery replacement. The cars are made from high-quality ABS plastic with metal components, so they can handle rough play and even the occasional drop from the track. The anti-skid tires work on pretty much any surface - tracks, floors, even carpets. These aren't just for tracks though - kids can race them independently on any smooth surface. The LED lights have multiple modes and the cars are just the right size for little hands. Perfect for birthday gifts, holidays, or just because - they encourage imaginative play and are seriously entertaining for both kids and parents. Watching these colorful cars zoom through dark tracks is like having a mini light show right in your living room! Just a heads up - the track isn't included, but these work with most popular track sets out there.
