All outdoor lights of cab use high flux LED chips with 50,000 hour lifespan. They produce up to 120 lumens per lamp while drawing less than 2 watts, eliminating frequent bulb changes.
Every lamp in this outdoor lights of cab kit is rated IP67 or higher. The housings are ultrasonically welded to prevent moisture ingress, critical for rainy African conditions.
The outdoor lights of cab are potted with thermal conductive silicone. This protects the circuit boards from road vibration and shock, ensuring long term reliability on rough roads.
Each light carries ECE R6, R7, R48, or R91 approval as applicable. The reflectors meet ECE R3 specifications. Using certified lights ensures legal compliance for international transport.
The left and right front LED clearance lamps are made from die cast aluminum housings with a black powder coat. The lens is UV stabilized polycarbonate that will not yellow for ten years. Inside, six surface mount LEDs produce a uniform light pattern. The lamp is sealed with a Gore membrane to equalize pressure. These lamps are direct replacements for the original units on HOWO MAX 4X2.
The left and right LED steering lamps are located on the bumper or door mirror brackets. Their amber LEDs produce a flash rate of 90 pulses per minute, synchronized with the flasher relay. The lens features a micro prism structure that spreads light horizontally. These lamps are SAE approved for use as side turn signals.
The door lamps are equipped with a built in door switch contact. When the door opens, a magnet closes the reed switch inside the lamp. The lamp then illuminates for 30 seconds. A timer circuit automatically turns it off to save battery. The door reflecting plates are made from acrylic with a microprismatic reflector film. They reflect light from headlights up to 150 meters away.
The left and right LED marker lights have a chrome plated bezel and contain three LEDs. They are wired to come on with the parking lights. The rear clearance lamps of wind deflector (NJ – 17) have a slim profile to fit under the wind deflector edge. They use side firing LEDs that shine through a prismatic red lens, creating a wide visibility angle of 180 degrees.
The kit includes hex flange nut M6 made from class 8 steel. The flange has a serrated underside that bites into the mounting surface, preventing loosening. The nut is coated with zinc trivalent passivation for corrosion resistance. Torque specification is 8 to 10 Nm. Use these nuts to secure the clearance lamps and marker lights to their brackets.
This outdoor lighting kit is designed for the HOWO MAX 4X2 with standard height roof and low mounted bumper. It also fits the sleeper cab variant. The left and right components are handed correctly. All connectors match the original vehicle harness. No cutting or splicing is required. For the wind deflector mounted rear clearance lamps, pre drilled holes exist on the wind deflector edge.
Tested in Nigerian conditions, these outdoor lights of cab continue to function after 1000 hours of vibration at 4g acceleration. The LED clearance lamps survived salt spray testing for 500 hours without corrosion. The door lamps operated at 80 degrees Celsius interior temperature with no fading. The reflecting plates maintained reflectivity after two years of UV exposure.
Total power consumption for all lamps combined is less than 25 watts. This is 80 percent less than incandescent bulbs. Reduced current draw means less alternator load and longer battery life. The LED technology also generates less heat, reducing fire risk. For fleets, lower electrical load translates to fuel savings over time.
Start by removing the old lights and cleaning the mounting surfaces. Apply a small amount of dielectric grease to the connectors. Install the left and right front clearance lamps using two hex flange nuts M6 each. Torque to 8 Nm. Then mount the left and right LED steering lamps on the bumper brackets.
Use the original screws. For the door lamps, plug the connector into the door harness and snap the lamp into the cutout. The door reflecting plates attach with the adhesive tape after cleaning with isopropyl alcohol.
Mount the left and right LED marker lights on the cab roof or fender. Finally, install the wind deflector rear clearance lamps by inserting them into the rubber grommets on the wind deflector. Test all Outdoor Lights of Cab for function before returning the truck to service.
Each outdoor light carries a 12 month warranty against LED failure or water ingress. Defective units will be replaced directly. The hex flange nuts are not warranted but can be purchased separately. For warranty claims, provide the production date code printed on the lamp housing. Keep the original packaging for return shipping. Authorized HOWO dealers in Nigeria stock these lights for quick replacement.
Aftermarket Outdoor Lights of Cab often use counterfeit LEDs that dim after a few months. Their housings are made from recycled plastic that cracks under UV. The genuine HOWO outdoor lights of cab use virgin polycarbonate and original brand LEDs. The lens optics are computer designed for correct beam pattern. Aftermarket lights may fail ECE compliance tests, resulting in fines during roadside inspections. Investing in genuine parts avoids these problems.
Buying the full set of outdoor lights of cab ensures all lamps match in color temperature and brightness. Individual purchases may result in mismatched amber shades or different LED count. The kit includes all necessary mounting hardware (nuts, washers, screws). It also comes with a wiring diagram specific to the HOWO MAX 4X2. This simplifies ordering and inventory management for workshops and fleets.
The outdoor lights of cab contain no mercury or hazardous heavy metals. The LEDs are RoHS compliant. The plastic housings are marked with recycling codes. At end of life, the lamps can be disposed of as electronic waste. The reflecting plates are pure acrylic and recyclable. Using LED lights reduces carbon footprint due to lower energy consumption.
Drivers report that the LED clearance lamps are clearly visible even in heavy rain. The door lamps prevent slips when stepping out at night. The turn signals are bright enough to be seen in direct sunlight. The wind deflector rear clearance lamps help parking in tight spaces by showing the cab corners. Many fleet operators have converted all their HOWO MAX 4X2 trucks to this genuine LED kit.
The outdoor lights of cab are packed in custom foam lined boxes to prevent damage. Each lamp is individually wrapped in anti static plastic. The hex flange nuts are in a separate poly bag. The box includes a quick start installation sheet. The package dimensions are 40x30x15 cm, weight 2.5 kg. Bulk orders for 10 or more kits are shipped on pallets with reinforced corners.
The left and right front clearance lamps operate at 12V and 24V DC systems. The LED driver circuit includes reverse polarity protection. The rear clearance lamps of wind deflector use a two wire connection with no polarity requirement. All lamps meet IP67 dust and water ingress protection standards. The reflecting plates are compliant with FMVSS 108 for side reflectors.
