20466304 Light Module | IP69K & SAE J1455 Thermal Management
20466304 Light Module Control Unit
Multi-Function Headlight Controller
The 20466304 Light Module assembly (20466304, 20942846, 20953573) integrates advanced PWM dimming circuitry for precise headlight level management. Die-cast aluminum housing dissipates heat from high-current circuits during extended operation. Rotary encoder with 36-position resolution enables accurate beam angle adjustment. Sealed membrane switches resist fluid ingress in FMX construction environments. Dual-color LED indicators display active lighting modes (position/daytime running). Galvanically isolated CAN-bus interface prevents electrical interference in FH16 models. Vibration-dampened mounting system protects internal components on rough terrain. UV-resistant polycarbonate lens maintains clarity under solar exposure. Tool-free access panel simplifies fuse replacement in FM9 applications. Integrated thermal cut-off protects against overload conditions. Reverse polarity protection safeguards electronics during battery replacement procedures.
