This kit made lighting a caboose I built very easy. The components are small and the lighting is perfect. The circuitry insures both steady brightness and continuous lighting regardless of track polarity or dead spots. Additional resistors are supplied if you wish to decrease the brightness. The kit came with everything necessary including truck wheel contacts (trucks are not supplied). This kit makes purchasing and assembling the individual components unnecessary. I highly recommend this kit for anyone thinking about lighting a caboose, or any other railroad car where lighting is desired.
