This left rear taillight (OE:41331001035D001B) adheres to Dongfeng’s genuine standards, exclusively designed for Dongfeng DFAC trucks. Its high-bright LED light source offers 30% higher luminosity than halogen alternatives, ensuring clear brake, turn, and reverse signals even in heavy rain, fog, or night driving—critical for preventing rear-end collisions. Crafted from high-impact PC lens (anti-scratch & anti-yellowing) and robust ABS housing, it withstands bumpy long-haul roads. With IP67 waterproof/dustproof certification, it avoids short circuits from water intrusion, maintaining stable performance in all harsh weather conditions.
