5 Inch 45W 3 600 Lumens 6000K
The SLL-5046 is a 5 inch round LED driving light designed for off-road vehicles that operate in dark, dusty, and high-vibration environments. It delivers 3600 effective lumens with a spot beam pattern, providing a clear and bright long-range beam for safe navigation on unpaved roads and trails. The die-cast aluminium housing and polycarbonate lens resist impact and environmental damage, while the 9–32V DC operating range ensures compatibility with both 12V and 24V vehicle electrical systems. The light includes overvoltage and overheat protection, and the IP68 sealing prevents dust and water ingress during off-road use.
- 3600 effective lumens with a spot beam pattern illuminate distant terrain on unpaved roads and trails
- IP68 sealing prevents dust and water ingress during off-road driving and pressure washing
- 9–32V DC operation allows use on both 12V and 24V vehicles without changing part numbers
- Overvoltage and overheat protection extend service life in unstable electrical environments
- Die-cast aluminium housing and polycarbonate lens resist impact and UV degradation
Where This Lamp Is Used
- Front bumper mounting on off-road vehicles and 4x4s used in mining, forestry, and desert terrain
- Auxiliary lighting on utility vehicles and service trucks operating on unlit rural roads
- Night driving on construction sites and remote job sites where visibility is critical
- Fleet vehicles used in agriculture and logging that travel on unpaved and muddy roads
- Replacement for halogen driving lights that fail under vibration and heat stress
Who It Is For
- Distributors of off-road vehicle lighting needing a single part number for 12V and 24V systems
- 4x4 accessory brands building a private label driving light range with consistent performance
- Machinery OEMs fitting driving lights on production vehicles with limited mounting space
- Fleet operators replacing halogen lights that fail after a few hundred hours of use
- Off-road vehicle modifiers installing lights on custom builds with tight bumper mounting constraints
Problems It Solves
- Halogen driving lights burn out quickly under vibration and heat, requiring frequent replacement
- Cheap plastic lenses degrade under UV exposure and become brittle after a few months
- Inadequate sealing allows water and dust to enter, causing internal fogging and electrical failure
- Narrow voltage range limits use across different vehicle electrical systems, increasing SKUs
- Lack of overvoltage protection leads to premature LED failure during alternator surges

How It Compares With the Alternatives
| Round 5 inch light with flood beam | Spot beam reaches further ahead for long-range visibility while flood covers a wider area but at shorter range |
|---|---|
| Light with 12V only operation | 9–32V DC range allows use on both 12V and 24V systems, reducing the number of SKUs needed |
| Light without overvoltage protection | Built-in protection prevents damage during alternator surges, extending service life in unstable electrical environments |
How to Fit and Use It
- Mount the light on the bumper using the included bracket, ensuring the bracket aligns with the mounting holes on the vehicle
- Route the cable away from moving parts and heat sources, and keep the connector sealed when not in use
- Aim the spot beam at the road ahead, adjusting for distance and terrain; avoid aiming at oncoming traffic
- Clean the polycarbonate lens with water and a soft cloth only; avoid solvents that may 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.
Do you have a minimum order quantity
