LED Warning Light
The SLL-6020A is a 4 inch LED forklift safety warning light designed for industrial environments where visibility and durability are critical. Two 10W CREE LEDs produce a 10° spot beam in both red and blue, projecting 1000 lumens to warn pedestrians and vehicles of approaching forklifts in warehouses, loading bays, and tight work zones. The die-cast aluminium housing with IP68 sealing and UV-resistant polyester coating ensures long life in dusty, wet, or high-vibration conditions. The light operates on 9–48V DC, making it compatible with both 12V and 24V forklift systems without requiring voltage regulators.
- 10° spot beam focuses light over distance to warn pedestrians and vehicles ahead, not just in the immediate area
- Dual red and blue beams increase visibility and recognition in busy industrial environments
- IP68 sealing prevents water and dust ingress during washdowns or outdoor use
- 9–48V DC operation allows one part number to fit 12V and 24V forklifts, reducing inventory
- 50,000 hour lifespan means replacement is needed less than once per year under normal use
Where This Lamp Is Used
- Front and rear warning lighting on forklifts operating in high-traffic warehouse aisles
- Side-mounted warning lights on forklifts used in narrow loading bays or tight storage areas
- Fleet-wide safety upgrades for warehouse operators replacing older incandescent warning lights
- Installation on electric forklifts where electrical noise from motors could interfere with unshielded lights
- Use on forklifts operating in outdoor yards or docks where exposure to rain, dust, and temperature extremes is common
Who It Is For
- Fleet operators upgrading forklift safety systems with reliable, long-life warning lights
- Warehouse managers needing consistent warning signals across multiple forklift models
- Machinery OEMs integrating safety lighting into new forklift builds with a single part number
- Distributors selling forklift safety accessories who need a compact, high-visibility light
- Equipment dealers fitting warning lights on used forklifts before resale
Problems It Solves
- Flickering or failing incandescent warning lights that burn out before 1000 hours
- Lights with poor beam focus that scatter light in all directions instead of warning ahead
- Non-IP68 sealed lights that fail after a single washdown or exposure to coolant spray
- Single-color warning lights that blend into the environment and are ignored by workers
- Voltage-sensitive lights that fail on 24V systems or require additional voltage regulators
- Lights with plastic housings that crack under impact or degrade under UV exposure

Lens bonding and gasket sealing for IP68 integrity
Quality Control on This Model
- Photometric output verified in an integrating sphere
- Sealing tested to IP68 standard under pressure and immersion
- Vibration testing on a vibration test machine to simulate forklift operation
- Salt spray corrosion testing on housing and mounting hardware
- High and low temperature alternating humidity testing across the -40 to +85 degrees Celsius range
Customisation Options
- Deutsch connector instead of standard 40cm bare wire lead
- Single-color version (red only or blue only) instead of dual
- Private label logo on the housing and printed carton
- Alternative cable length to match specific forklift harnesses
- Mixed cartons combining this light with other SUNLITEC models for trial orders
How It Compares With the Alternatives
| Single-color LED warning light | Dual red and blue beams increase recognition in high-traffic zones |
|---|---|
| Flood beam warning light | Spot beam projects light further ahead for early warning, flood spreads light too wide |
| Smaller 3 inch warning light | Same beam focus but larger 4 inch body allows better heat dissipation and higher lumen output |
How to Fit and Use It
- Mount on a flat surface using the standard bracket and verify the 4 mounting holes align with your forklift's existing holes
- Route the 40cm bare wire lead away from moving parts and keep the cable entry pointing downward
- Use a 3A fuse on the positive feed to protect against overcurrent
- Aim the spot beam at the ground ahead of the forklift to warn pedestrians and vehicles in the path
- Clean the PC lens with water and a soft cloth only; avoid solvents that degrade the anti-UV 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
