This OE 3714170-C6201 truck side reading lamp adopts integral high-toughness PC injection molded housing, with anti-aging matte surface finish to avoid yellowing and cracking under long-term sun exposure and road vibration. An independent tactile push button switch is embedded on the lamp surface, enabling drivers to control local lighting separately without turning on the main overhead cabin lamp, effectively reducing unnecessary 24V power drain when parked. The built-in LED lamp bead assembly outputs uniform soft focused light without harsh glare, suitable for checking logistics documents, reading maps and personal night rest inside the cab. The rear integrated plug socket is 1:1 matched with Dongfeng GX & KX original cab wiring harness, supporting direct clip-on snap installation without cutting cables or extra adapters, greatly shortening interior repair time. Internal metal conductive terminals are plated with anti-rust coating to prevent poor contact caused by cab humidity.
