Lamp – Genuine HOWO MAX 4X2 Ambient LED Interior Light Kit

The part system in the HOWO MAX 4X2 cab provides essential ambient illumination for night driving and cabin comfort. This genuine HOWO lamp kit includes a high-quality ambient LED light and the necessary mounting screws for a secure installation. When you choose authentic Howo Parts, This part assembly guarantees OE fitment, long-lasting brightness, and a perfect match with the interior trim. Below are detailed descriptions of every component included with This part assembly.

Ambient light

The ambient light is a premium LED lamp that provides soft, diffused illumination for the cab interior. This part is designed to reduce eye strain during night driving while enhancing the cabin’s aesthetic appeal. The part housing is made from high-impact polycarbonate with a matte black finish, blending seamlessly with the overhead console. The part uses energy-efficient LEDs that deliver a warm white glow with a colour temperature of 4000K, creating a comfortable atmosphere for the driver and passengers. This part is rated for 24V operation and consumes only 3W of power,

making it an economical choice for continuous use. The part’s integrated diffuser ensures even light distribution without glare, and its slim profile allows it to be installed in tight overhead spaces.

The part is also weather-sealed to IP54, protecting it from dust and moisture, which is essential for the demanding environment of a heavy truck. Replacing a faded or damaged lamp with this genuine HOWO unit restores the original brightness and ensures that the cab remains well-lit during night shifts. The part’s simple plug-and-play design makes installation quick and hassle-free, and its durable construction ensures years of reliable service.

Hexalobular socket pan head screw

Three hexalobular socket pan head screws (Torx) are supplied to secure the ambient light lamp to its mounting bracket. These lamp screws are made from stainless steel with a corrosion-resistant finish, providing a secure and durable fastening solution for The part. The pan head design offers a large bearing surface that prevents the screw from pulling through The part housing,

while the Torx drive ensures positive engagement and reduces the risk of cam-out during installation. The screws are M4x10 in size, matching the mounting holes of The part perfectly. When installing The part, these screws should be torqued to 2.5 Nm to avoid over-tightening and damaging the plastic housing.

The included screws eliminate the need to search for compatible fasteners, making The part replacement process straightforward. Using the correct lamp screws is essential to prevent The part from loosening due to cab vibration, which could cause rattling or intermittent electrical contact. These lamp screws are also suitable for other interior trim components, making them a versatile addition to any workshop’s hardware stock.

How the Ambient LED Lamp Enhances Cab Lighting

Unlike harsh white lights, This part emits a warm white glow that mimics natural daylight, reducing eye strain during night driving.

The part’s low power consumption means it can be left on without draining the vehicle’s battery. The part’s diffuser panel ensures that light is spread evenly, eliminating hotspots and shadows.

Whether you are resting during a break or preparing for a night shift, This part provides the right amount of light for a comfortable cab environment. Replacing a worn or dim lamp with a genuine HOWO unit restores the original lighting quality and enhances the overall driving experience.

Installation Guide for The part Kit

Before installing The part, disconnect the vehicle battery to avoid electrical shorts. Remove the old lamp by unscrewing the existing fasteners and gently pulling The part from its housing.

Clean the mounting area and ensure the wiring connector is free from corrosion. Position the new ambient lamp into the mounting bracket, aligning the screw holes with the bracket. Insert the three Torx screws and hand-tighten them evenly, then torque to 2.5 Nm using a Torx driver.

Connect the electrical plug to The part, ensuring it clicks securely. Reconnect the battery and test The part by turning on the interior light switch. If The part does not illuminate, check the fuse and the wiring connection. The part should emit a warm, even glow. The installation is now complete.

Troubleshooting Common Lamp Issues

If The part flickers or does not turn on, check the electrical connector for loose pins or corrosion. A poor connection can cause intermittent lighting. Ensure The part is fully pushed into the connector. If The part is dim, the voltage supply may be low; check the battery and alternator output. A buzzing sound from The part may indicate a faulty driver circuit; replace The part immediately.

If The part housing is cracked or the lens is fogged, moisture has entered the unit; replace The part to prevent short circuits. Loose screws can cause The part to rattle; retighten the Torx screws to 2.5 Nm. Always use genuine lamp components for replacement to guarantee correct fit and electrical compatibility.

Maintenance and Service Intervals for The part

The ambient lamp requires minimal maintenance. Inspect The part lens for dust or dirt; clean it with a soft, dry cloth to maintain maximum brightness. Check the electrical connector annually for corrosion and apply dielectric grease if needed.

The part’s LED has a very long life (over 50,000 hours), so it rarely needs replacement. However, if The part becomes dim or fails, replace it promptly. Keep spare lamp screws in the vehicle’s toolbox in case of loss. Regular inspection of The part ensures consistent cabin illumination and contributes to driver comfort and safety.

Compatibility and Applications of The part Kit

This part kit is specifically designed for the HOWO MAX 4X2 tractor cab and is compatible with all production years from 2018 onward.

The part fits both standard and high-roof cab variants. It is also suitable for SITRAK C7H and HOWO T7H models that share the same interior lamp mounting points. The part is not compatible with older A7 or WD615 models, which use a different lamp housing and connector type. Always verify your vehicle’s cab interior configuration before ordering This part kit.

Why a Genuine Lamp Is Essential for Cab Comfort and Safety

Aftermarket lamps often use inferior LEDs that produce harsh, blue-tinged light that causes eye strain and headaches. Generic lamp housings may not fit correctly, leading to rattling or even falling out during driving.

Non-genuine fasteners may strip or corrode, making removal difficult. A failed cab lamp can leave the driver in darkness during a breakdown, creating a safety hazard. Genuine HOWO lamp components are manufactured to SINOTRUK’s exacting standards, using high-quality LEDs, robust housings, and precise fasteners. The small additional cost of a genuine lamp is insignificant compared to the comfort and safety it provides for the driver.
