Side marker lights are essential safety devices that indicate the width and position of a commercial vehicle. Reliable side marker lights make the HOWO MAX 4X2 tractor visible to other road users from the side, especially at night or in poor weather. This genuine HOWO side marker lights kit includes left and right LED lamps and all necessary mounting hardware.
When you choose authentic Howo Parts, you receive a complete side marker lights solution engineered specifically for the MAX 4X2 cab.
The left LED marker light is a compact, high brightness amber lamp mounted on the left side of the cab roof or fender. This side marker light uses six surface mount LED chips that produce a wide 180 degree visibility pattern. The housing is die cast aluminum with a black powder coat finish that resists corrosion. The lens is made from UV stabilized polycarbonate that will not yellow or crack after years of sunlight exposure.
The left LED marker light is wired to illuminate whenever the parking lights are on, marking the left edge of the vehicle. This side marker light meets ECE R48 and FMVSS 108 requirements for side clearance lamps on vehicles over 2.1 meters wide. The lamp is sealed to IP67 standard, preventing dust and moisture ingress even when driving through deep puddles or in heavy rain.
The right LED marker light is the mirror image lamp mounted on the right side of the cab. This side marker light is identical to the left unit in construction and light output, providing symmetrical marking of the vehicle width. The right LED marker light helps oncoming traffic judge the lateral position of the truck, reducing the risk of side collisions. Like its counterpart,
this side marker light uses LED technology that draws only 1.5 watts while producing light equivalent to a 5 watt incandescent bulb. The long 50,000 hour LED life means this side marker light will likely never need replacement during the vehicle’s service life. The right unit also includes a built in voltage regulator that accepts 12V or 24V DC systems, making it compatible with all HOWO electrical architectures.
The hex flange nut M6 is used to secure both LED marker lights to their mounting brackets or directly to the cab sheet metal. Four nuts are supplied in the side marker lights kit, enough for both lamps with two nuts each. These nuts feature an integrated flange that distributes clamping pressure evenly across the lamp housing, preventing stress cracks in the plastic or aluminum.
The flange also eliminates the need for a separate flat washer. The M6 thread mates with the studs molded into the lamp housing, and the serrated underside bites into the mounting surface to prevent loosening from vibration. This side marker lights fastener is made from zinc plated steel with a corrosion resistant coating, ensuring that it will not rust and seize over time. The nuts are designed to be tightened to 6 Nm of torque, which is sufficient to hold the lamp securely without damaging the housing.

These side marker lights use high flux LED chips that produce a bright, uniform amber light visible from over 300 meters. The LED technology consumes only 1.5 watts per lamp, reducing electrical load on the vehicle alternator. The 50,000 hour lifespan eliminates frequent bulb changes and reduces maintenance costs.
Each side marker light is sealed with an ultrasonic welded lens and a Gore Tex membrane that equalizes internal pressure while blocking moisture. The IP67 rating means the lamp can be submerged in one meter of water for 30 minutes without damage, perfect for driving through flooded roads or heavy rain.
The die cast aluminum housing provides excellent thermal management and structural rigidity. The side marker lights are potted with silicone compound that protects the circuit board from vibration damage, ensuring reliable operation on rough African roads.
These side marker lights carry ECE R48 approval for side clearance lamps and meet FMVSS 108 requirements. Using certified lights ensures your HOWO MAX 4X2 complies with international safety regulations and passes roadside inspections.
Side marker lights are required by law on commercial vehicles over 2.1 meters wide. Their purpose is to warn other drivers of the vehicle’s presence and approximate width when viewed from the side. This is especially important at intersections, when changing lanes, or when the truck is parked on the shoulder at night.
The amber color of these side marker lights is universally recognized as a warning for vehicle width. By clearly marking the front and rear edges of the cab, these lights help prevent side collisions that can push the truck off the road or into oncoming traffic. In poor visibility conditions such as fog, rain, or dust, the side marker lights provide an additional layer of conspicuity that can save lives.
Traditional incandescent side marker lights use a glass bulb with a tungsten filament that vibrates and eventually fails. The glass bulb can also break from road shock or thermal stress. LED side marker lights have no filament to break, no glass to shatter, and they consume 80% less electricity. The instant on/off response of LEDs is also faster than incandescent bulbs,
giving other drivers a more immediate warning. While the initial cost of LED side marker lights is higher, the long term savings from reduced maintenance and longer life make them the economical choice for fleet operators. These genuine HOWO LED side marker lights are designed to last the entire service life of the vehicle, eliminating the need for regular bulb replacements.
The housing of each side marker light is made from A380 aluminum alloy, which provides excellent heat dissipation for the LEDs. The black powder coat finish is electrostatically applied and baked for a durable, corrosion resistant surface that will not peel or fade. The lens is molded from Bayer Makrolon polycarbonate, the same material used for automotive headlights.
A silicone rubber gasket between the housing and lens provides the primary water seal. The circuit board is FR4 grade with 2 oz copper traces and a conformal coating that protects against humidity and vibration. Each side marker light contains six 5630 SMD LEDs in a parallel series configuration, so if one LED fails, the others continue to operate. The constant current driver accepts input from 9V to 32V DC, making the lamp suitable for 12V and 24V systems without modification.
The M6 hex flange nut is a class 8 steel fastener with a yellow zinc finish. The flange diameter is 14mm, which provides a wide bearing surface that prevents the nut from pulling into plastic lamp housings. The hex height is 5mm, and the wrench size is 10mm across flats.
The nut features a serrated underside that creates a positive lock when torqued to 6 Nm, preventing loosening from vibration. These nuts are also resistant to galvanic corrosion when used with aluminum housings because the zinc coating acts as a sacrificial barrier. The M6 thread pitch is 1.0mm, which is the standard fine pitch for M6 fasteners in automotive applications. Each nut is individually inspected for thread quality and plating thickness before being packaged.
Before starting, disconnect the battery ground cable. Locate the existing mounting holes on the left and right sides of the cab roof or fenders. If holes are not present, mark and drill 6mm holes. Clean the mounting surface thoroughly. Peel the protective backing from the lamp housing gasket. Position the left LED marker light over the holes, ensuring the wiring pigtail is oriented downward to prevent water entry.
Insert the studs through the holes. From inside the cab or fender well, install the hex flange nut M6 onto each stud. Tighten to 6 Nm using a 10mm socket. Do not overtighten, as this could crack the housing. Connect the lamp wires to the parking light circuit: black to ground, red to positive. Repeat the same procedure for the right LED marker light. Reconnect the battery and test the lights. The side marker lights should illuminate whenever the parking lights are turned on.
These side marker lights are designed for all HOWO MAX 4X2 tractors with standard cab or sleeper cab. They fit the factory mounting holes on the cab roof and also on the fenders.
The lamps are compatible with both left hand drive and right hand drive configurations, as the left and right positions are symmetrical. For vehicles with custom bodywork, the low profile design (only 15mm thick) allows mounting in tight spaces. The 6mm mounting stud spacing is 58mm center to center, which matches the standard hole pattern on HOWO cabs. If your vehicle has a different mounting pattern, adapter brackets are available separately.
Inspect the side marker lights every 20,000 kilometers or during routine vehicle service. Check the lens for cracks, yellowing, or moisture inside the housing. If moisture is present, the seal has failed and the lamp should be replaced. Verify that the mounting nuts are still tight; retorque to 6 Nm if needed. Clean the lens with a soft cloth and mild soap solution.
Do not use abrasive cleaners or pressure washers directed at the lamp, as this can force water past the seals. If an individual LED fails, the lamp will still function but with reduced output; replacement is recommended. The hex flange nut M6 can be reused if the serrations are still sharp; otherwise, replace with a new nut.
If a side marker light does not illuminate, first check the parking light fuse. If the fuse is good, test the lamp by connecting it directly to a 12V battery. If the lamp works, check the wiring for corrosion or loose connections. If the lamp does not work, the internal driver may have failed; replace the lamp. If one lamp is dimmer than the other, check for voltage drop in the wiring harness.
If the lens is fogged internally, the seal has failed and the lamp must be replaced to prevent short circuits. Loose mounting nuts can cause the lamp to vibrate excessively, leading to internal component failure. Always use genuine HOWO side marker lights for replacement, as aftermarket lamps may have different mounting stud spacing or incorrect light output.
Aftermarket side marker lights often use lower quality polycarbonate that yellows and crazes within a year. The LEDs may be underpowered and dim, or they may be overpowered and overheat. The housings are often made from recycled plastic that becomes brittle and cracks. The sealing is often inadequate, allowing moisture to enter and corrode the circuit board.
The mounting studs may be positioned incorrectly, requiring modification to the cab. Genuine HOWO side marker lights are manufactured to the highest standards, using certified materials and rigorous quality control.
