7 Inch 73W Flush Mount High Low Beam LED Head Light
The SLL-7073 is a 7 inch flush mount LED headlight designed to replace original equipment headlights on off-road vehicles, trucks, and heavy machinery that operate in extreme conditions. It delivers a high beam of 5110 effective lumens and a low beam of 3850 effective lumens, ensuring visibility in darkness, dust, and rain. The die-cast aluminium housing with UV polyester powder coating resists corrosion, while IP68 sealing prevents water and dust ingress during pressure washing or exposure to mud. Overvoltage and overheat protection improve reliability in unstable electrical environments.
- High beam delivers 5110 effective lumens and low beam 3850 effective lumens for clear visibility in darkness and poor weather
- Flush mount design fits original headlight housing without requiring body modifications
- IP68 sealing prevents water and dust ingress during pressure washing or off-road use
- 9 to 32V operating range supports both 12V and 24V vehicle systems, reducing SKU count
- Overvoltage and overheat protection extend lifespan in unstable electrical environments
Where This Lamp Is Used
- Replacement headlight on off-road vehicles and 4x4s used in mining, forestry, and construction
- Primary lighting on trucks and engineering vehicles operating in remote areas with no street lighting
- Fleet vehicles used in agriculture and utility services that run at night or in low visibility
- Heavy machinery like excavators and cranes that require reliable lighting for night operations
- Vehicles used in salt-laden environments where corrosion resistance is critical
Who It Is For
- Machinery OEMs replacing original halogen headlights with LED on production lines
- Fleet operators upgrading lighting on 12V and 24V vehicles to reduce maintenance
- Distributors selling LED headlight replacements for off-road and industrial vehicles
- 4x4 accessory brands building private label headlight kits for aftermarket sale
- Equipment dealers fitting lighting on machines before delivery to end users
Problems It Solves
- Original halogen headlights fail early under vibration and draw excessive current from the alternator
- Non-sealed LED headlights fog up or fail after exposure to rain, mud, or pressure washing
- Narrow beam or low lumen output leaves the road ahead dark during night driving
- Voltage fluctuations in 24V systems damage unprotected LED drivers
- Painted metal housings corrode quickly in salt or chemical environments

How It Compares With the Alternatives
| Round 7 inch LED headlight | Flush mount design fits original headlight housing without body modifications, unlike protruding models |
|---|---|
| Single beam LED headlight | Dual high and low beam allows safe driving in both open and oncoming traffic conditions |
| Lower voltage range LED headlight | 9–32V range supports both 12V and 24V systems, reducing the number of SKUs needed |
How to Fit and Use It
- Ensure the flush mount surface is clean and flat before installation to maintain IP68 sealing
- Route the cable away from moving parts and heat sources to avoid damage
- Keep the cable entry pointing downward to prevent water ingress
- Aim the high beam at the road ahead and low beam at the near field to avoid blinding oncoming traffic
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.
