4x6 45W Flush Mount Convex Lens High Low Beam LED Head Light Version 2
The SLL-5045 is a 4x6 inch flush mount LED headlight designed to replace original equipment headlights on off-road vehicles, trucks, and heavy machinery. It delivers 3150 effective lumens with a high-low beam option, ensuring visibility in both close and distant conditions. The die-cast aluminium housing with UV-resistant polyester powder coating and IP68 sealing ensures durability in rain, dust, and vibration. Built for 9–32V operation, it runs on both 12V and 24V systems without requiring a different part number.
- 3150 effective lumens with high-low beam option for both near and distant visibility
- Flush mount design fits original headlight housing without body modification
- IP68 sealing prevents water and dust ingress during pressure washing or off-road use
- 9–32V operating range supports both 12V and 24V vehicle systems with one part number
- 50,000 hour lifespan reduces replacement frequency on machines with long operating cycles
Where This Lamp Is Used
- Replacing original halogen headlights on off-road vehicles and utility trucks operating in wet or dusty conditions
- Fitting as a primary headlight on excavators and cranes used in night construction or mining operations
- Upgrading lighting on full-size SUVs and 4x4s used in remote or unlit terrain
- Installing on fleet vehicles that require consistent lighting across 12V and 24V platforms
- Mounting on engineering vehicles where vibration and exposure to weather degrade standard headlight assemblies
Who It Is For
- Machinery OEMs integrating a direct replacement headlight into new vehicle builds
- Fleet operators upgrading older vehicles with longer-lasting LED lighting
- Distributors sourcing a single model that works on both 12V and 24V systems
- 4x4 accessory brands developing a private label headlight with high beam versatility
- Equipment dealers fitting replacement headlights on machines with damaged or outdated lighting
Problems It Solves
- Original halogen headlights fail early under vibration and draw excessive current from the vehicle’s electrical system
- Non-sealed headlights fog up or fail after exposure to rain, mud, or pressure washing
- Inconsistent performance across 12V and 24V systems forces dealers to stock multiple part numbers
- Narrow beam patterns leave the immediate work zone in shadow while distant visibility is poor
- Painted metal housings degrade under UV exposure and salt spray, leading to corrosion

How It Compares With the Alternatives
| Round 4 inch headlight | The 4x6 inch flat profile fits flush into standard headlight housings without protrusion |
|---|---|
| Single beam LED headlight | High-low beam option provides both close and distant visibility without needing two separate units |
| Larger 6x8 inch headlight | Lower output but fits in compact headlight housings where larger units will not clear |
How to Fit and Use It
- Verify the 4x6 inch flush mount dimensions match the original headlight housing before installation
- Leave a drip loop in the 40cm lead to prevent water from running into the gland
- Use the high beam for distant visibility and low beam for close work or oncoming traffic
- Clean the polycarbonate lens with water and a soft cloth only—avoid solvents that degrade the coating
