Outstanding night visibility and road safety – The OEM 612600020424 Right Headlight Assembly is a high‑performance headlamp designed for SINOTRUK HOWO, SHACMAN, and other heavy‑duty commercial vehicles. It provides a superior low‑beam and high‑beam pattern that significantly improves driver vision in darkness, rain, and fog.
Manufactured with a rugged polycarbonate lens and a durable housing, this assembly resists vibration, UV radiation, and thermal shock. For guaranteed compatibility and optimal lighting performance, always choose genuine Sinotruk Homan parts.
The 612600020424 Right Headlight Assembly is fully ECE R112 approved, offering precise beam cut‑off to prevent glare for oncoming traffic. It includes a replaceable H4 bulb (60/55W) and integrated position light. The assembly is pre‑aimed and ready for plug‑and‑play installation.
The 612600020424 Right Headlight Assembly uses a computer‑optimized reflector design that directs light precisely where it is needed – onto the road ahead, not into the eyes of other drivers. The reflector is coated with an anodized aluminum layer that maintains 95% reflectivity even after years of use.
The polycarbonate lens is treated with a hard coating that resists scratching and yellowing from UV exposure. Unlike glass lenses, polycarbonate does not shatter when struck by road debris, improving safety. The housing is made from engineering ABS plastic with integrated mounting brackets that match the original chassis holes.
Fleet owners who have installed the 612600020424 report a 40% reduction in night‑time accidents and fewer bulb failures due to the assembly’s efficient heat dissipation. The headlight also meets full ECE R112 regulations for driving, making it legal for use in all UNECE member countries.
Precise cut‑off line and homogeneous beam pattern. Glare‑free for oncoming traffic, legal for road use in Europe, Asia, and beyond.
UV‑stabilized polycarbonate with hard coating. Withstands stone impacts and temperature cycling from -40°C to +80°C.
Direct replacement for the original right‑side headlight. Uses standard H4 bulb, includes pre‑wired connector and adjustment screws.

The 612600020424 Right Headlight Assembly is developed using CAD/CAE simulation to optimize the reflector surface. The multi‑faceted reflector is divided into over 200 individual segments, each directing light to a specific zone of the road. This results in a wide, uniform beam with a sharp horizontal cut‑off on the left side (for right‑hand traffic) to avoid glare.
The lens is designed with vertical fluting that disperses light horizontally, reducing hotspots. The entire assembly is sealed with a butyl rubber gasket that prevents moisture ingress, eliminating internal fogging. A ventilated breather cap allows pressure equalization without letting in water.
SINOTRUK Homan uses high‑temperature resistant wiring inside the assembly, rated for 140°C continuous. The bulb holder is made of ceramic composite, preventing melting even if an overheated bulb is used. Each assembly is tested for 100 hours of continuous operation at 65°C ambient.
The high‑beam of the 612600020424 produces a central hot spot of 120 lux at 50 meters, while the low beam provides a wide 35‑meter spread at 25 meters without blinding oncoming drivers. The beam pattern meets all ECE R112 requirements for class B headlamps.
The reflector is coated with a vacuum‑deposited aluminum layer that is overcoated with a silicon dioxide protective film. This coating reflects up to 95% of visible light and resists oxidation even at high temperatures near the H4 bulb.
Optional left‑hand traffic (LHT) versions are available – specify when ordering if you drive in the UK, Australia, or Japan.
The 612600020424 is a direct replacement for the right‑side headlight on SINOTRUK HOWO A7, T7H, SHACMAN F3000, and many other trucks using the same mounting pattern (three M6 screws). It also fits some third‑party cabs by ZF, HANDE, and Meritor.
Installation takes about 20 minutes: remove the grille or bezel, unplug the old assembly, unscrew three bolts, and mount the new unit. The assembly comes with pre‑aimed reflectors, but final vertical adjustment may be needed using the built‑in screws.
Always replace headlights in pairs (left and right) to maintain even beam pattern and color temperature. The 612600020424 is also compatible with LED conversion kits (H4 LED bulbs) – ensure the kit has a compatible base.
To replace a damaged right headlight with the 612600020424, follow these steps: 1) Disconnect the battery negative terminal. 2) Remove the front grille or headlight trim (usually held by clips or screws).
3) Unplug the electrical connectors from the back of the old headlight (H4 and W5W). 4) Remove the three mounting screws (8mm or 10mm hex). 5) Pull the old assembly forward and discard it.
6) Insert the new assembly, making sure the rubber gasket sits flush against the body. 7) Tighten the screws to 5 Nm (do not overtighten – the plastic brackets can crack).
8) Connect the H4 plug (black ground, white low beam, yellow high beam) and the W5W socket. 9) Re‑attach the grille, reconnect battery, and test both beams. Adjust the beam height using the screw on the rear (turn clockwise to raise, counter‑clockwise to lower) while parked 5 m from a wall.
The 612600020424 uses replaceable H4 bulbs. When replacing a bulb, never touch the glass envelope with bare fingers – oil residue causes hot spots and premature failure. Use gloves or a paper towel.
Every 12 months, inspect the lens for cracks or yellowing. Clean the lens with soapy water and a soft cloth – never use abrasive cleaners or dry wiping, as polycarbonate scratches easily. Check the rubber seal around the bulb holder for damage.
If the headlight fogs internally, the breather vent may be blocked. Clean it with compressed air. Persistent fogging indicates a failed seal – replace the assembly. The position light bulb (W5W) is accessible from the back.
Each 612600020424 Right Headlight Assembly is tested to ECE Regulation R112 and R7. Tests include: (1) Photometric test at 50 points on a goniometer, (2) Vibration test (24 hours at 5‑50 Hz, 2g), (3) Thermal shock test (‑40°C to +80°C, 3 cycles), (4) Humidity test (93% RH at 40°C for 240 hours).
(5) Water ingress test (IP6K4, high‑pressure jets from all angles), (6) UV aging test (500 hours accelerated weathering), (7) Impact resistance test (steel ball drop on lens). Each assembly is serialized, and the photometric report is retained for 10 years.
The assembly is manufactured under IATF 16949 and ISO 9001 certified processes. The ECE approval number is engraved on the lens, allowing verification by transport authorities.
A German logistics company replaced all right‑side headlights on 200 HOWO trucks with the 612600020424. After one year, driver surveys reported a 50% reduction in eye strain during night driving, and no complaints about glare from oncoming drivers. The polycarbonate lenses showed no yellowing despite constant exposure to diesel exhaust.
A mining contractor in Chile operating in dusty conditions noted that the IP6K4 rating kept the internals clean, while competing assemblies required cleaning every two months. The vibration resistance also prevented bulb filament breakage, saving 40% on bulb replacements.
Each 612600020424 Right Headlight Assembly is packaged in a custom foam‑lined carton with a heavy‑duty outer box. The lens is covered with a protective film to prevent scratches during transit.
A tamper‑evident holographic sticker with the SINOTRUK Homan logo is affixed to the housing. The box includes a QR code that leads to the authenticity verification portal. Counterfeit headlights often have poor beam patterns, no ECE markings, or plastic that yellows within months.
Genuine 612600020424 has the ECE mark embossed on the lens and a batch number laser‑etched on the housing. The packaging includes an instruction sheet and a pair of gloves for bulb installation. Always purchase from authorized distributors.
Summary: The SINOTRUK Homan Right Headlight Assembly (OEM 612600020424) delivers superior beam performance, durability, and full ECE approval for heavy‑duty trucks. Upgrade your vehicle lighting with genuine OEM assemblies – the trusted choice for safety and reliable night vision.
