The WG166424307 Left Lamp Shade is a high-quality, impact-resistant lighting cover designed specifically for the left-side lamp assemblies of SINOTRUK Howo heavy-duty trucks. As a leading provider of genuine Sinotruk howo parts, we offer this OEM-grade left lamp shade as a direct replacement for the original factory component. The WG166424307 shade provides durable protection for the left headlight, turn signal, or combination lamp, shielding the bulb and reflector from stones, moisture, dust, and road debris while ensuring optimal light transmission. Manufactured from high-grade polycarbonate with advanced UV-stabilizing additives, this left-side shade resists yellowing, crazing, and impact damage, maintaining its optical clarity and structural integrity even after prolonged exposure to harsh sunlight, extreme temperatures, and off-road environments.
The WG166424307 left lamp shade is engineered to preserve the original beam pattern and brightness, ensuring that your truck remains clearly visible to other motorists and complies with ECE lighting regulations. Its precision fit and robust construction make it an essential replacement part for restoring both safety and aesthetics on the driver’s side.
OEM direct replacement • UV-stabilized polycarbonate • Impact & scratch resistant • Left-side specific design • Easy clip-on installation
The WG166424307 is a left-side lamp shade (also called a lens cover or light housing protector) designed for the SINOTRUK Howo A7 and T7H series trucks. It serves as the protective outer cover for the left front combination lamp, which typically includes the headlight, turn signal, and parking light functions. This OEM-grade shade precisely matches the original part’s contours, clip locations, and optical properties, ensuring a seamless fit and consistent light performance after replacement.
Manufactured from high-impact polycarbonate with a durable hard-coat scratch-resistant layer, the WG166424307 offers superior resistance to stone chips, minor abrasions, and chemical attack from road salts and cleaning agents. Its optically clear (or lightly smoked) finish delivers excellent light transmittance, allowing the full luminous flux of the bulb to reach the roadway while protecting the internal reflector and bulb from moisture, dust, and corrosive contaminants.
The shade is also formulated with UV-absorbing compounds that prevent yellowing and hazing over time – a common failure mode of inferior aftermarket covers. By maintaining optical clarity, the WG166424307 ensures that left-side signals and headlights remain highly visible, reducing the risk of side-impact collisions and enhancing overall road safety for both the driver and other road users.
This left lamp shade is specifically handed for the driver’s side and is interchangeable with earlier revisions (WG166424306). It is a popular choice for collision repairs, UV-damage replacements, or fleet-wide lighting restorations. Its lightweight yet rugged design reduces the risk of shattering in minor impacts, protecting the expensive lamp assembly behind it.
The WG166424307 Left Lamp Shade is specifically engineered for the left (driver’s) side front combination lamp of SINOTRUK Howo A7 and T7H series trucks, including models ZZ4257, ZZ3257, and other variants with the same lighting housing design. It is a direct replacement for the original left-side lamp cover and is also backward-compatible with the earlier part number WG166424306.
This left shade is used in conjunction with the main headlight unit, turn signal, and position light. It is specifically handed for left-hand drive (LHD) configurations, but it also fits right-hand drive trucks where the left side corresponds to the passenger side – always verify the vehicle’s orientation. The WG166424307 is a popular choice for collision repairs, UV-damage replacements, and fleet-wide lighting upgrades.
In demanding applications such as long-haul transport, mining, construction, and military logistics, the left lamp shade is constantly exposed to flying stones, insects, mud, and harsh chemicals. The WG166424307 is built to withstand these elements, preserving the left-side lighting performance and ensuring continuous compliance with ECE and DOT safety regulations.
When replacing a cracked, hazy, or missing left shade, always confirm the lamp type (halogen, LED, or HID) and the housing dimensions, although the WG166424307 fits the vast majority of Howo A7 and T7H left lamp assemblies. For fleets, this part helps maintain consistent left-side lighting across the entire vehicle inventory.
Replacing the WG166424307 left lamp shade is a simple, tool-free task that typically takes less than 5 minutes. Start by opening the hood to access the rear of the left headlight assembly or, if the shade is externally clipped, work from the front of the vehicle. Locate the four retaining clips on the existing shade – these are visible as small tabs around the perimeter.
Gently press each clip inward while pulling the shade outward. If the shade is stuck due to dirt or rubber seal adhesion, use a plastic trim tool to carefully pry it loose without damaging the housing or paint. Once removed, clean the lamp housing with a soft, lint-free cloth to remove dust, dead insects, and moisture.
Align the new WG166424307 shade over the left housing, ensuring that the clips line up with their corresponding slots. Press firmly around the entire perimeter until you hear each clip snap securely into place. Visually inspect that the shade sits flush and that no gaps exist between the shade and the housing.
For maintenance, regularly wash the left shade with mild soap and water to remove road grime and insect residue. Avoid using abrasive cleaners, solvents, or pressure washers at close range, as these can damage the hard coat. If the shade becomes scratched, light polishing with a plastic-safe compound can restore clarity.
Inspect the shade periodically for cracks, yellowing, or loose clips. A damaged left shade should be replaced immediately to protect the lamp internals and maintain proper light output. The WG166424307 is designed for long service life, but harsh environments may accelerate wear, so regular checks are recommended.
The WG166424307 Left Lamp Shade is manufactured in an ISO 9001-certified facility using advanced injection-molding technology. The raw polycarbonate resin is sourced from globally recognized suppliers and compounded with a proprietary blend of UV absorbers, heat stabilizers, and impact modifiers to meet SINOTRUK’s rigorous performance standards.
Each left shade undergoes a series of quality checks, including optical clarity measurement (haze < 2%, transmission > 88%), accelerated UV aging (3500 hours per SAE J576), and impact resistance testing (DIN 53373). Clip retention force is also verified to ensure that the shade stays securely attached even under severe vibration and wind loads.
We back the WG166424307 with a comprehensive warranty against material and workmanship defects. Our quality control processes ensure that every shade delivers the same optical performance, fit, and durability as the original factory part, giving you confidence in your truck’s left-side lighting reliability.

By replacing it with this genuine OEM-grade left shade, you restore the original light intensity and beam pattern on the driver’s side, ensuring that your turn signals and headlights are clearly visible to oncoming traffic and pedestrians. The UV-stabilized material prevents the clouding and hazing that plague cheap knock-offs, keeping your truck’s front end looking professional and ensuring that your lighting remains effective for years.
Fleet managers will appreciate the quick, clip-on installation that minimizes labor time and vehicle downtime – a critical factor in high-utilization operations.
