Märklin 73404 H0 LED Interior Lighting Kit for Passenger Cars

The Märklin 73404 is a dedicated interior lighting kit for H0 passenger cars, using warm white LEDs to create a realistic, inviting glow. Unlike generic lighting strips, it is engineered for Märklin rolling stock and operates on both digital and analog layouts, with an integrated capacitor that prevents flicker over dirty track or switches.

Highlights

• Warm white LED illumination for a prototypical interior ambience
• Works on digital (DCC/MFX) and conventional AC/DC layouts
• Integrated capacitor ensures flicker-free operation
• Low power consumption, maintenance-free LED technology

In daily use

Install the board inside a compatible Märklin H0 passenger car and connect it to the track pickups. The LEDs light up as soon as track power is present, with no bulbs to replace. The warm white colour temperature complements coach interiors and enhances night-time operation.
