Utilizing advanced Reflector Facing Technology and producing 2500 lumens per lamp, this ECE-certified 20W kit provides both long-range visibility and superior peripheral illumination. Built for extreme durability with a 10G vibration rating and IP67 waterproof protection, it is the ultimate street-legal auxiliary lighting solution for any vehicle.
A New Standard in Wide-Range Visibility The PIAA DKW539E represents the pinnacle of the LPW530 series, offering a massive leap in light output and beam coverage compared to previous generations. This 3.5-inch round LED lamp is specifically engineered to solve the challenge of seeing both distance and detail simultaneously. Featuring PIAA’s signature Reflector Facing Technology (RFT), the DKW539E delivers a high-intensity 6000K white beam that combines long-range reach with a wide-angle spread, ensuring no detail is missed on winding roads or high-speed motorways.
Key Technical Advantages:
-
Hybrid Wide Driving Beam: The DKW539E is unique in its ability to project a beam that is both wide and long simultaneously. This "2-in-1" lighting profile provides excellent distance visibility while illuminating the shoulders of the road and tight corners.
-
Reflector Facing Technology (RFT): By aiming the high-output LEDs rearward into a computer-designed multi-surface reflector, PIAA achieves 100% light capture. This results in a precise, powerful beam pattern that maximizes lumen output while maintaining strict control to avoid glare.
-
Professional 2500lm Output: Each lamp generates 2500 Raw Lumens, producing a staggering 53,100cd of luminous intensity. This ensures daylight-like clarity (6000K) even in the pitch-black conditions of rural or off-road environments.
-
ECE R112 Approved: This kit is fully street-legal and ECE certified, meeting rigorous international standards for safety and beam quality.
-
Robust 20W Performance: Operating at 20W per lamp, it offers an incredible brightness-to-power ratio. The powder-coated aluminum housing is rated for 10G vibration resistance and is IP67 waterproof, making it suitable for cars, trucks, and motorcycles.
-
Advanced Thermal Management: Features updated internal heat dissipation technology (Effective Dec 2025) to ensure consistent performance and an extended lifespan during prolonged use.
