Marklin 73400 Standard Interior Lighting Kit
One 73400 is required for a short car (example: Langenschwalbach cars); for long cars (example: UIC-x at 28.2 cm / 11-1/8 length) two 73400 are required. The circuit boards can be plugged together in a series or they can be shortened. Mounting hardware is included. The separate 73404, 73405 or 73406 pickup shoe / ground spring power feed set, or the 72020 current-conducting coupler with the 72050 ground spring is required, depending on the car type.
Highlights:

• Coziness in the car: soft light LEDs.
