LED BEZEL LESS LED DRIVIN LIGHT 4800lm 48W
The SLL-4048D is a bezel-less LED driving light designed for off-road vehicles and heavy machinery that operate in extreme conditions. With 4800 effective lumens from a 48W power draw, it provides a wide, even beam pattern that illuminates the full path ahead without glare or hot spots. The die-cast aluminium alloy housing is sealed to IP67 and rated for -45 to +85 degrees Celsius, making it suitable for use in arctic winters and desert heat. The 10-32V DC operating range supports both 12V and 24V systems, reducing the number of SKUs needed in fleet or OEM applications.
- 4800 effective lumens spread evenly across a wide beam pattern, reducing glare and improving visibility on rough terrain
- IP67 sealing prevents dust and water ingress during off-road use and pressure washing
- 10-32V DC input allows one part number to serve both 12V and 24V vehicle systems
- Die-cast aluminium alloy housing resists deformation under impact and dissipates heat efficiently
- 50000 hour lifespan means replacement is measured in years, not months, reducing downtime
Where This Lamp Is Used
- Front lighting on off-road vehicles and 4x4s used in mining, forestry, and construction
- Auxiliary lighting on cranes and excavators operating at night in remote locations
- Fleet vehicles used in cold climates where standard lights fail at -40 degrees Celsius
- Trucks and buses operating in dusty desert environments where sealed lights fail
- Agricultural machinery running long shifts under low light conditions
Who It Is For
- Distributors of 12V and 24V vehicle lighting who need a single part number for both systems
- Machinery OEMs fitting driving lights on production lines and requiring consistent mounting patterns
- Fleet operators replacing halogen or older LED lights that fail under vibration and temperature extremes
- 4x4 accessory brands building a private label driving light range with a clean, modern look
- Equipment dealers supplying lights for machines used in harsh environments
Problems It Solves
- Halogen driving lights fail under vibration and draw excessive current from the vehicle’s electrical system
- Sealed beam lights with bezels create shadow zones and reduce effective light output at the edges
- Lights with narrow beam patterns leave the sides of the vehicle dark, increasing collision risk
- Standard lights fail in extreme cold or heat due to poor thermal management or material brittleness
- Lights with low IP ratings allow water and dust in, leading to short circuits after a few wash cycles
Technical Features
- 48W real power draw with 4800 effective lumens output
- Wide beam pattern with no central hot spot due to bezel-less design
- Die-cast aluminium alloy housing with a semi-gloss black finish
- IP67 sealing rated for dust and water immersion up to 1 meter for 30 minutes
- Operating voltage range of 10 to 32V DC, compatible with 12V and 24V systems
- Operating temperature range from -45 to +85 degrees Celsius
- Bare wire lead of 40cm as standard, with Deutsch connector available on request
- No visible bezel, allowing full light emission across the entire lens surface
- Lifespan rated at more than 50000 hours under continuous operation

How It Compares With the Alternatives
| Traditional LED driving light with bezel | Bezel-less design eliminates shadow zones and increases effective light output at the edges |
|---|---|
| Narrow beam driving light | Wide beam covers the full path ahead without leaving the sides of the vehicle dark |
| Standard 12V only driving light | 10-32V range supports both 12V and 24V systems, reducing SKU count |
| Plastic housing light | Die-cast aluminium alloy resists impact and heat better than plastic, improving durability |
How to Fit and Use It
- Mount on a flat surface using the bottom bracket and verify the 40mm bracket width matches the machine bracket before drilling
- Wire through a fused feed sized for 4A at 12V or 2A at 24V and keep the cable entry pointing downward
- Leave a drip loop in the 40cm lead to prevent water from running into the gland
- Aim the wide beam at the path ahead and use a spot light separately for long-distance visibility
- Clean the polycarbonate lens with water and a soft cloth only—avoid solvents that can damage the anti-reflective coating
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.
What is the lead time
Sample orders normally take around 3 to 7 working days. Bulk lead time depends on the model and the quantity ordered.
