The WG9925720001/3 Left Lamp is a meticulously manufactured component that upholds the rigorous standards of SINOTRUK’s original equipment. Featuring a high‑clarity polycarbonate lens, a precision‑engineered reflector, and a robust housing, this lamp provides superior beam pattern and light intensity, ensuring excellent visibility for the driver while minimising glare for oncoming traffic.
With the WG9925720001/3 reference number, this lamp is precisely dimensioned to fit the original mounting points and electrical connectors of SINOTRUK Howo trucks. The lens is coated with an anti‑scratch and UV‑resistant layer to maintain clarity and transparency over years of exposure to sun, road debris, and harsh weather.
The housing is fully sealed to prevent moisture ingress, eliminating fogging and internal corrosion. The reflector is computer‑optimised to produce a sharp cut‑off line and wide spread of light, maximising the driver’s field of vision while meeting regulatory standards for beam pattern and intensity.
