4 Inch 30W Flush Mount LED Fog Light with Bracket
The SLL-4032 is a 4 inch flush mount LED fog light designed to replace original equipment headlights on off-road vehicles, trucks, and heavy machinery. It delivers 2100 effective lumens with a low beam pattern, operates across a 9 to 32V DC range, and is built for continuous use in extreme conditions with IP68 sealing and a 50,000 hour lifespan. The die-cast aluminium housing and durable polycarbonate lens resist impact, UV degradation, and corrosion, making it suitable for machines exposed to dust, rain, and vibration.
- Flush mount design replaces original headlights without requiring body modifications
- 2100 effective lumens with low beam pattern provide clear visibility in fog, rain, and dust
- 9 to 32V DC operation supports both 12V and 24V vehicle systems, reducing SKU count
- IP68 sealing prevents water and dust ingress during pressure washing or off-road use
- Overvoltage and overheat protection extend service life in unstable electrical environments
Where This Lamp Is Used
- Front fog lighting on off-road vehicles and 4x4s used in wet or dusty terrain
- Auxiliary lighting on trucks and engineering vehicles operating in low-visibility conditions
- Replacement for original headlights on fleet vehicles where OEM parts are no longer available
- Mounting on excavators and cranes where space is limited and flush fit is required
- Lighting on utility vehicles and service trucks that operate in variable weather
Who It Is For
- Distributors sourcing replacement fog lights for 12V and 24V vehicle fleets
- Machinery OEMs integrating a flush mount fog light into new machine designs
- Fleet operators replacing failed halogen fog lights with longer-lasting LED alternatives
- 4x4 accessory brands building a private label fog light range with OEM compatibility
- Equipment dealers fitting fog lights on used or modified vehicles for resale
Problems It Solves
- Original headlights fail quickly under vibration and exposure to moisture in off-road use
- Non-flush mount lights require body cutting and create aerodynamic drag or snag points
- Low-lumen fog lights leave the immediate area around the machine dark in poor visibility
- Voltage fluctuations in older vehicles damage standard LED lights without protection
- Painted metal housings corrode or peel after repeated washing or salt exposure
Technical Features
- Three 10W CREE LEDs with a real power draw of 30W and 2100 effective lumens

- Die-cast aluminium housing with durable UV-resistant polyester powder coating
- Anti-impact polycarbonate lens with UV protection and scratch resistance
- Overvoltage and overheat protection circuits to prevent damage from electrical surges
- IP68 sealing with a gasketed cable entry to resist water, dust, and pressure washing
- 9 to 32V DC input range compatible with 12V and 24V vehicle systems
- Operating temperature range from -40 to +60 degrees Celsius
- Flush mount design with optional bracket mount for flexible installation
- 50,000 hour rated lifespan under continuous operation

- Private label logo on the housing and printed carton
- Custom cable length to match a specific machine harness
- Mixed cartons combining this fog light with other SUNLITEC models for trial orders
How It Compares With the Alternatives
| Round 4 inch fog light with external bracket | Flush mount fits flush with the vehicle body and avoids snag points, while the bracket version allows tilt adjustment |
|---|---|
| LED fog light with 12V only operation | 9 to 32V DC range supports both 12V and 24V fleets without changing part numbers |
| Fog light with lower IP rating | IP68 sealing prevents water and dust ingress during pressure washing and off-road use |
How to Fit and Use It
- Install flush with the vehicle body using the standard mounting pattern and check clearance before drilling
- Leave a drip loop in the 40cm lead so water runs away from the gland rather than into it
- Use the optional bracket mount if tilt adjustment is needed for beam aiming
- Clean the polycarbonate lens with water and a soft cloth only, as solvents may degrade the UV coating
Questions About This Model
