4x6 45W Truck High Low Beam Amber LED Headlight
The SLL-5043 is a 4×6 inch flush-mounted amber LED headlight designed for trucks and heavy machinery that operate in rain, dust, and extreme temperatures. Nine 5W Bridgelux LEDs deliver 3300 effective lumens with a high-low beam option, providing clear visibility in low-light conditions without glare. The die-cast aluminium housing with UV-resistant polyester powder coating and IP68 sealing ensures long-term durability in harsh environments, while the 9–32V DC operating range supports both 12V and 24V vehicle systems.
- Flush mounting reduces aerodynamic drag and protects the lens from impact on off-road terrain
- Amber light improves visibility in rain, fog, and snow compared to white light
- High-low beam option allows one lamp to serve as both main and auxiliary lighting
- IP68 sealing prevents water and dust ingress during pressure washing and prolonged exposure
- 9–32V DC input covers both 12V and 24V vehicle systems, reducing SKU count for fleet operators
Where This Lamp Is Used
- Front lighting on delivery trucks and utility vehicles operating in rainy climates
- Auxiliary headlight on excavators and cranes working at night in wet or dusty conditions
- Side and front lighting on mining trucks and engineering vehicles exposed to constant vibration
- Fleet vehicles with mixed 12V and 24V electrical systems needing a single headlight model
- Trucks used in agriculture and construction where flush mounting avoids snagging on branches or debris
Who It Is For
- Fleet operators managing mixed 12V and 24V vehicle fleets who need a single headlight model
- Machinery OEMs fitting headlights on production line vehicles with flush mounting requirements
- Distributors selling truck and industrial lighting who require a weather-resistant amber option
- 4x4 accessory brands building a private label headlight range with high beam versatility
- Equipment dealers fitting lighting on machines used in wet or dusty environments
Problems It Solves
- Standard white headlights cause glare and reduce visibility in rain and fog
- Non-flush headlights catch on branches, rails, and equipment during operation
- Non-IP68 sealed lights fail after repeated wash cycles or exposure to dust and moisture
- Halogen or low-lumen LED headlights require frequent replacement due to short lifespan
- Lack of high-low beam option forces buyers to stock two separate models for different needs
- Voltage sensitivity in cheap LEDs causes failure in 12V or 24V systems without a wide input range
Technical Features
- Nine 5W Bridgelux LEDs with a total real power draw of 45W and 3300 effective lumens
- High-low beam option selectable via a single switch or relay control
- Flush mounting design with a compact 4×6 inch footprint and low profile
- Die-cast aluminium housing with durable UV-resistant polyester powder coating
- Polycarbonate lens with anti-reflective and impact-resistant properties
- Overvoltage and overheat protection circuits prevent damage from electrical surges
- Operating temperature range of -40 to +85 degrees Celsius for extreme climate use
- 9–32V DC input supports both 12V and 24V vehicle systems without voltage conversion
- IP68 sealing protects against water immersion and dust ingress during operation
- Bare wire lead of 40cm standard, with connector options available on request

How It Compares With the Alternatives
| Standard white LED headlight | Amber light improves visibility in rain and fog but has lower lumen output than white |
|---|---|
| Non-flush headlight | Flush mount reduces drag and protects the lens from impact but requires a flat mounting surface |
| Single beam headlight | High-low beam option allows one lamp to serve dual purposes, reducing the number of SKUs needed |
| Lamp with 12V only input | 9–32V DC range supports both 12V and 24V systems, eliminating the need for separate models |
How to Fit and Use It
- Mount flush on a flat surface using the provided bracket pattern and check the 4×6 inch footprint before drilling
- Leave a drip loop in the 40cm lead to prevent water from entering the gland
- Use the high beam for long-range visibility and low beam for close-up work to avoid glare
- Clean the polycarbonate lens with water and a soft cloth only—avoid solvents that degrade 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.
