Frontier Car LED Marker Lamp
The P46 Series LED Rail Car Marker Lamp is engineered to exceed the performance, durability, and service life of traditional incandescent sealed-beam lamps used across rail car lighting applications. Designed for harsh operating environments, the P46 Series delivers reliable illumination under continuous vibration, wide voltage fluctuations, and long duty cycles common in rail and rugged industrial use.
Built with a die-cast aluminum housing and a hard-coated polycarbonate lens, the P46 Series offers significantly higher impact resistance and environmental durability than conventional glass-encased lamps. Its solid-state LED design ensures stable performance over a wide 24–90V DC operating range, reducing sensitivity to voltage variation while maintaining consistent light output.
The P46 Series is fully compatible with most existing rail car fixtures, enabling straightforward retrofit upgrades without mechanical modification. With a 25,000-hour rated lifetime, high-intensity red LED output, and 5-year full performance warranty, the P46 Series provides a long-term, low-maintenance lighting solution for rail operators focused on reliability and lifecycle cost reduction.

Technical FAQ
Is the P46 car marker the same as a 12-inch railroad crossing light?
No. This P46 product is a round red LED rail car marker lamp. Select a crossing-light model when the installation calls for a 12-inch grade-crossing warning signal.
What electrical input and connection does this car marker use?
The published configuration lists 24–90Vdc input. The CO1 configuration uses rear screw terminals; confirm the exact order code and wiring drawing before installation.
What should be checked when replacing a sealed-beam car marker?
Match the fixture opening and depth, mounting and sealing, voltage, polarity, connection style, and required red indication. The product description calls this a 5½-inch round form factor; verify the mechanical dimensions against the drawing.
