This OE 37QC9-73020-AE right rear combination lamp combines brake lamp, reverse lamp, turn signal and marker light in one assembly, meeting all rear signal lighting requirements of Dongfeng Captain light trucks. The transparent and red PMMA lens is added with anti-ultraviolet formula, effectively avoiding yellowing and light attenuation after long-time outdoor use. The whole lamp body adopts ultrasonic hot-melt sealing technology between lens and ABS housing, effectively stopping rainwater and dust from penetrating into the lamp cavity to prevent internal fogging and bulb burnout. The reserved mounting lugs and plug-in wiring connector completely follow original vehicle design standards, no wiring modification or gasket processing needed during replacement. Internal light cavity layout optimizes light distribution angle, ensuring uniform light output and high visibility under night, rainy and foggy driving conditions.
