Forklift Safety Lighting
The SLL-6020C is a 4 inch red LED forklift safety light designed to prevent pedestrian and vehicle collisions in industrial environments. Four 5W LUNIMUS LEDs project a clear, bright red line beam on the ground around the forklift, creating a visible boundary that warns nearby workers and operators not to approach. The light operates on 9–48V DC, survives extreme temperatures from -40 to +85 degrees Celsius, and is sealed to IP68, making it suitable for use in dusty, wet, and high-vibration warehouse and factory settings.
- Projects a precise red line beam on the ground to mark a safe exclusion zone around forklifts
- IP68 sealing prevents water and dust ingress during washdowns and in high-moisture environments
- Operates reliably across 9–48V DC, compatible with 12V, 24V, and 48V forklift electrical systems
- 50,000 hour lifespan reduces replacement frequency and maintenance downtime
- Overvoltage and overheat protection prevent damage from electrical spikes or prolonged operation
Where This Lamp Is Used
- Side and rear mounting on forklifts in busy warehouse aisles to prevent pedestrian entry into blind zones
- Installation on industrial vehicles in manufacturing plants where forklifts operate near walkways
- Use in high-traffic loading docks where multiple forklifts and personnel share the same space
- Mounting on forklifts used in cold storage facilities operating at -40 degrees Celsius
- Integration into fleet safety systems where consistent visual warnings are required across multiple machines
Who It Is For
- Fleet operators managing forklifts in warehouses, factories, and distribution centers
- Machinery OEMs fitting safety lighting as a standard feature on new forklift models
- Industrial equipment dealers offering safety upgrades to existing forklift fleets
- Facility managers implementing safety compliance measures in high-risk work zones
- Distributors of industrial vehicle lighting seeking a reliable, low-maintenance safety light
Problems It Solves
- Pedestrians walk into forklift blind spots because there is no visible boundary marking the danger zone
- Forklifts without visual warnings increase the risk of leg injuries and collisions in tight spaces
- Standard warning lights fail in dusty or wet environments due to poor sealing or lens fogging
- Inconsistent voltage across forklift fleets requires multiple part numbers for different systems
- Lights with short lifespans need frequent replacement, increasing maintenance workload
Technical Features
- Four 5W LUNIMUS LEDs with a total output of 1000 effective lumens
- Line beam pattern projects a continuous red line on the ground for clear visual warning
- 9–48V DC operating range supports 12V, 24V, and 48V forklift systems without voltage conversion
- Die-cast aluminium housing with semi-gloss black UV-resistant polyester powder coating
- Durable polycarbonate lens with anti-scratch and UV protection
- IP68 sealing prevents ingress of water and dust during washdowns and in harsh conditions
- Overvoltage and overheat protection circuits prevent damage from electrical surges or prolonged use
- Operating temperature range from -40 to +85 degrees Celsius for use in cold storage and high-heat environments
- Bare wire lead of 40cm standard, with connector options available on request

How It Compares With the Alternatives
| Standard warning beacon or flashing light | Line beam creates a continuous boundary that is easier to see and interpret than a flashing point source |
|---|---|
| Low-cost plastic safety light | Die-cast aluminium housing and polycarbonate lens resist impact and UV degradation over time |
| Non-IP68 rated light | Sealed construction prevents water and dust ingress during daily washdowns and in high-moisture areas |
| Single voltage light (12V only) | 9–48V operation supports multiple forklift systems without requiring different SKUs |
| Halogen-based safety light | 20W LED draws less than half the current of a comparable halogen unit and lasts 10 times longer |
How to Fit and Use It
- Leave a drip loop in the 40cm lead to prevent water from running into the gland
- Aim the line beam across the ground at the forklift’s operating radius to create a clear exclusion zone
- Clean the polycarbonate lens with water and a soft cloth only—avoid solvents that may damage the anti-scratch 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
There is an MOQ for standard orders, but smaller orders are also accepted, which suits distributors testing a new model.
How is the lamp shipped
Samples usually go by DHL, UPS, FedEx or TNT in around 4 to 7 days. Bulk orders ship by air in about 7 to 15 days or by sea in about 15 to 30 days.
Will this lamp work on both 12V and 24V forklifts
Yes. The operating range is 9–48V DC, so the same part number works on 12V, 24V, and 48V systems.
Can you supply the lamp with our own brand
Yes. OEM and ODM service is available, including a private label logo on the housing and printed cartons.
Is it approved for industrial safety use
The lamp is IP68 sealed, has overvoltage and overheat protection, and is designed for use in industrial environments where safety lighting is required.
