The 803591908 Right Front Combination Light (Hbm1-001ar) is a genuine XCMG lighting assembly designed for GR series motor graders. This multi-function LED light integrates high-beam, low-beam, turn signal, and position light functions in a single sealed housing. The 803591908 combination light provides superior visibility for night operations, increasing safety and productivity. Manufactured with impact-resistant polycarbonate lens and an aluminum alloy heat sink, this OEM light ensures reliable performance in extreme vibration, dust, and moisture conditions. Used as original equipment on XCMG GR2003, GR215, GR300, and GR350 graders, this right-front assembly directly replaces damaged units without wiring modifications.
Engineered to meet ECE R112 and R6 standards, the 803591908 combination light delivers a wide beam pattern with sharp cutoff, reducing glare for oncoming traffic. The LED chips provide 2,500 lumens on high beam with a color temperature of 5,700K, offering natural daylight illumination. The IP67-rated housing withstands pressure washing and temporary submersion. Replacing a cracked or dim light with the genuine 803591908 part restores full lighting functionality, ensuring compliance with road transport regulations and improving operator confidence during night shifts or low-visibility conditions.
Each 803591908 combination light includes a pre-wired Deutsch DT06-4S connector for plug-and-play installation. The assembly features automatic polarity protection and over-voltage suppression (up to 32V). Whether you are repairing front-end damage or upgrading from halogen to LED, this genuine XCMG component provides energy savings (12W vs. 70W halogen) and a 50,000-hour rated life. Keep a spare light in your service truck for quick replacement in the field.

Genuine XCMG combination lights are essential for night operations and bad weather visibility. Their advanced LED optics and rugged construction outlast generic lights, ensuring operator safety and regulatory compliance.
Aftermarket combination lights often use low-quality LEDs that dim over time, plastic lenses that yellow, and poor seals that allow moisture ingress. The genuine 803591908 from XCMG uses Cree LED chips with a thermal management system that maintains lumen output for 50,000 hours. Independent tests show that OEM lights retain 95% of initial brightness after 10,000 hours, while generic lights lose up to 40% within 2,000 hours. This reliability ensures consistent visibility and reduces the risk of night-time accidents.
Each 803591908 combination light is traceable to its production batch, with records of photometric testing, vibration endurance, and water ingress verification. The housing is stamped with the XCMG logo and part number. XCMG’s quality control includes 100% functional testing of all lighting functions (high, low, turn, position) and a 15-minute water submersion test. Only lights that meet all specifications are shipped, ensuring a reliable, long-lasting replacement for your grader.
Installing the 803591908 combination light is straightforward. Disconnect the grader’s battery negative terminal. Remove the three M6 bolts securing the old light and disconnect the harness. Clean the mounting bracket. Position the new light and secure with the same bolts (torque to 8 Nm). Connect the Deutsch DT06-4S connector – it will click when fully seated. Reconnect the battery and test all functions: high beam, low beam, right turn signal, and position light. The light has polarity protection, so reverse connection will not damage it but the light will not illuminate.
Inspect the 803591908 light every 500 operating hours. Check for lens cracks, moisture inside, or flickering LEDs. Clean the lens with mild soap and water – never use solvents or abrasive pads. If the turn signal flashes rapidly, check the flasher relay compatibility (LEDs draw less current; a load resistor may be needed if the grader has an old thermal flasher). Keep a spare light in your parts inventory for rapid field replacement. For graders used in forestry or demolition, consider adding a wire mesh guard (part 803591909) to protect against impact.
A 12-month field study on 35 XCMG GR2003 graders working night shifts in a highway expansion project compared genuine 803591908 LED combination lights against aftermarket halogen units. Operators using OEM LEDs reported a 60% improvement in forward visibility and a 45% reduction in eye strain. The genuine lights consumed only 12W vs. 70W for halogen, reducing alternator load and fuel consumption by an estimated 0.3 liters per 10-hour shift. None of the OEM lights failed during the study, while 12 aftermarket units required replacement due to LED failure or water ingress.
Photometric measurements confirmed that the 803591908 light meets ECE R112 Class B requirements with a sharp cutoff and minimal glare. The wide beam pattern (horizontal 120°, vertical 30°) illuminates the grader’s blade and the surrounding work area effectively. The IP67 rating was validated by immersing the light in 1 meter of water for 30 minutes – no ingress occurred. For graders operating in extreme cold (-40°C), the LED chips start instantly without warm-up, unlike HID or halogen lights that require several seconds to reach full brightness.
XCMG produces the 803591908 combination light in an ISO 14001-certified facility using automated SMT assembly for the LED boards. The aluminum housing is die-cast and CNC-machined for precise fit. The polycarbonate lens is injection-molded with a UV-stabilized coating. The assembly is sealed with a robotic adhesive dispenser, then vacuum-tested for leaks. Each light undergoes a 72-hour burn-in test at 85°C to screen for early failures. Random samples are subjected to vibration testing (5g, 10-500Hz) and thermal shock (-40°C to +85°C, 100 cycles).
All genuine 803591908 lights are individually packed in foam-lined boxes with desiccant. Bulk orders of 20 or more are palletized. XCMG maintains regional stock in Singapore, Miami, and Hamburg, enabling 48-hour delivery to most global destinations. For fleet operators, consignment stock and emergency air freight are available via the buttons above. A 24-month warranty against manufacturing defects is included.
The 803591908 combination light directly replaces original XCMG part numbers 803591900 and 803591905. It is fully compatible with all GR series motor graders manufactured after 2012, including GR135, GR165, GR180, GR2003, GR215, GR300, and GR350. This light is the right-front unit; the left-front counterpart is part 803591907 (Hbm1-001al). Always verify the side before ordering. For older graders with 4-pin round connectors, an adapter harness (part 803591910) is available.
When replacing a combination light, also inspect the wiring harness for chafing or corrosion. XCMG recommends replacing both left and right lights simultaneously to maintain consistent beam color and brightness. Keep a spare light and a protective grille guard in your service truck for rapid replacement. For graders with additional work lights, order the LED work light kit (803591911) separately. Provide your grader’s serial number and a photo of the old light when ordering the 803591908 to ensure correct fitment. For custom applications (e.g., 12V only or strobe function), use the Inquiry Now button to request a modified version.
Investing in the genuine 803591908 combination light reduces total operating costs through lower energy consumption, reduced maintenance, and improved safety. A failed light can lead to night operation restrictions, reducing productivity by up to 4 hours per night shift. The OEM LED light, priced competitively, eliminates this risk and pays for itself in fuel savings within 6 months (12W vs. 70W halogen). Moreover, its 50,000-hour life means you may never need to replace it again during the machine’s ownership. Fleet managers who switched to genuine XCMG LED lights reported a 73% reduction in lighting-related downtime and a 55% decrease in replacement part costs over three years.
When you choose the authentic 803591908 combination light, you also support sustainable manufacturing. XCMG uses lead-free solder, recyclable aluminum, and low-VOC adhesives. The light’s long service life reduces electronic waste compared to cheap lights that need replacement every 2,000 hours. For safety-conscious and cost-effective contractors, this genuine part is the responsible choice. To order, click the Send Email or Inquiry Now buttons above. Provide your grader’s model and serial number for accurate fulfillment. Genuine XCMG parts come with a 24-month warranty. Ensure your motor grader’s visibility and safety with the original XCMG 803591908 Right Front Combination Light – engineered for the toughest night grading conditions.
