Upgrade your Kenworth lighting system with the ROADWEST LED 4x6-inch Headlight Housing Base with Wire Harnesses. Designed for trucks running 4x6 sealed-beam headlights, this assembly provides a solid mounting base and plug-and-play wiring for both halogen and LED lamps.

Engineered for popular Kenworth models using dual 4x6 headlights, including T400, T600, T800, W900, K100 and C500, this housing and harness kit is ideal for restoring damaged headlight mounts or supporting a modern LED upgrade.

The heavy-duty composite housing and weather-resistant connectors are built to withstand constant vibration, road grime and harsh weather. A direct-fit design helps you reuse existing mounting points, while the pre-terminated harness makes installation faster and cleaner.

LED-ready headlight base – supports 4x6-inch halogen or LED sealed-beam headlights.
Kenworth-specific fit – designed for T400, T600, T800, W900, K100 and C500 trucks using 4x6 lamps.
Plug-and-play harness – pre-wired connectors for easy installation and reliable power delivery.
