5.75 Inch 36W Flush Mount Convex Lens High Low Beam LED Head Light
The SLL-5036 is a 5.75 inch flush mount LED headlight designed to replace original equipment headlights on off-road vehicles and heavy machinery operating in extreme conditions. It delivers 2800 effective lumens with a high-low beam pattern, enabling safe visibility in dark terrain, rain, dust, and vibration. The die-cast aluminium housing with UV polyester powder coating resists corrosion, while IP68 sealing prevents water and dust ingress during pressure washing or exposure to mud. The 9–32V operating range ensures compatibility with both 12V and 24V systems, reducing the need for multiple SKUs.
- High-low beam pattern improves visibility in both open terrain and narrow trails without switching lamps
- 2800 effective lumens provide clear illumination across the entire driving path, not just a narrow hotspot
- Flush mount design fits existing headlight housings without requiring body modifications
- IP68 sealing and a durable polycarbonate lens prevent fogging and water ingress after repeated wash cycles
- 9–32V operating range allows one part number to serve both 12V and 24V vehicle fleets
Where This Lamp Is Used
- Replacing original halogen headlights on off-road vehicles used in mining and construction zones
- Fitting as a primary headlight on utility trucks and service vehicles operating in wet or dusty environments
- Installing on excavators and cranes where vibration and exposure to weather degrade standard lighting
- Upgrading lighting on full-size SUVs and 4x4s used for night patrols or emergency response
- Integrating into fleet vehicles that operate across multiple voltage systems without changing parts
Who It Is For
- Machinery OEMs replacing original headlights during production line assembly
- Fleet operators upgrading lighting on 12V and 24V vehicles with a single part number
- Distributors offering drop-in replacement headlamps for off-road and industrial vehicles
- 4x4 accessory brands building a private label headlight line with proven durability
- Equipment dealers fitting reliable lighting on machines sold to clients in harsh climates
Problems It Solves
- Original halogen headlights fail prematurely under vibration and moisture, requiring frequent replacement
- Non-flush mounted LED lights require body modifications and increase wind resistance
- Low-lumen or narrow beam headlights leave the driving path partially dark, increasing accident risk
- Inadequate sealing in aftermarket lights causes fogging and internal condensation after washing
- Voltage mismatch between 12V and 24V systems forces distributors to stock multiple SKUs
Technical Features
- Twelve 3W Bridgelux LEDs with a total real power draw of 36W and 2800 effective lumens
- High-low beam pattern with a clear distinction between wide and focused illumination
- Flush mount design with a compact profile that fits within original headlight housing dimensions
- Die-cast aluminium housing with durable UV polyester powder coating for corrosion resistance
- Anti-UV, impact-resistant polycarbonate lens with scratch-resistant surface
- Overvoltage and overheat protection built into the internal driver circuit
- Operating voltage range of 9–32V DC, compatible with 12V and 24V vehicle systems
- Operating temperature range of -40 to +60 degrees Celsius, suitable for extreme climates
- IP68 sealing rating ensures full protection against water and dust ingress
- 50,000 hour lifespan under continuous operation, measured at 50% lumen maintenance

How It Compares With the Alternatives
| Original halogen headlight | Draws 3A at 12V against roughly 6A for halogen and survives vibration that destroys filaments |
|---|---|
| Standard flush mount LED headlight | Higher effective lumen output and dual beam pattern improve visibility without increasing size |
| Non-flush LED headlight | Fits existing housing without body modifications and reduces aerodynamic drag |
| Low-voltage LED headlight | Operates down to 9V, suitable for vehicles with unstable alternators or weak batteries |
How to Fit and Use It
- Verify the flush mount dimensions match the original headlight housing before installation
- Do not use solvents on the polycarbonate lens—clean with water and a soft cloth only
- Aim the high beam at the road ahead and the low beam at the near path to avoid blinding oncoming traffic
- Check the gasket and seal after installation to ensure no water can enter the housing
Questions About This Model
Can I order a sample before placing a bulk order
Yes. Sample orders are welcome and mixed samples of different models in one shipment are accepted.
