The interior lighting system of the box trucks for sale is a smart, energy-efficient solution designed for operational excellence. Standard equipment includes four 24V LED panel lights (18W each), providing 2,800 lumens of uniform illumination (lux level ≥ 200 at floor height). The lights feature IP65-rated casings, resistant to water and dust, and are controlled by a central management system with three modes: full brightness, dim (50%), and emergency (backup battery operation for 4 hours). In electric models, the lighting is integrated with the vehicle’s CAN bus, automatically activating when the cargo door is opened and deactivating after 15 minutes of inactivity to conserve battery. Optional upgrades include motion sensors (PIR, range 5m), color temperature adjustment (3,000K-6,500K), and explosion-proof fixtures for hazardous materials transport. The wiring harness is shielded with braided stainless steel to prevent electromagnetic interference, and all connections are sealed with heat-shrink tubing for reliability.
