A few Micro K'NEX coaster cars include two small lights, which illuminate when the car is in motion - ideal if you want to operate your coaster in the dark.
Light-up coaster cars are supplied in sets such as the 34043 Dragon's Revenge coaster.
The cars can also be bought as individual items in our K'NEX shop.
Note that Hint R3 provides more information about building models using Micro K'NEX coaster cars and track.
The light-up car comes with 3 batteries already installed.
To replace the batteries, use a small Philips screwdriver to loosen the screws, then remove the battery door. Then insert 3 new batteries (LR41, AG3) into the battery compartment with the correct polarity (+/-) as shown in the photo.
