The wide 12–24V operating range makes it equally at home in passenger cars, SUVs, trucks, and commercial vehicles. With plug-and-play installation, a rotatable collar for beam fine-tuning, and a 3-year warranty backing every set, the HE-D3CPRO delivers a professional-grade HID-to-LED conversion without the complexity. \u003cem\u003eNote: Always verify local regulations regarding LED headlight replacements before installing on street-driven vehicles.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose the Heise Pro Series HE-D3CPRO?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits D3S, D3R \u0026amp; D8S:\u003c\/strong\u003e Covers three of the most common factory Xenon HID fitments in a single kit — ideal for a wide range of European and Asian vehicle applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e16,000 Lumens Per Set:\u003c\/strong\u003e 260% brighter than standard LED replacements — dramatically more light output than the factory HID bulbs being replaced in most applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12–24V DC Operating Range:\u003c\/strong\u003e Compatible with standard 12V passenger vehicles and 24V commercial or heavy-duty applications — one kit covers a broad range of vehicle types.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 mm Solid Copper Thermodynamic Core:\u003c\/strong\u003e Superior heat dissipation versus aluminum-core competitors, maintaining consistent output at just 46.1°C operating temperature.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Speed Smart Fan:\u003c\/strong\u003e Active cooling prevents thermal throttling and maintains full-brightness output across the bulb's lifespan — no output degradation over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully Rotatable Collar:\u003c\/strong\u003e Precise beam alignment for projector and reflector housings ensures a clean cutoff line and optimal light projection for your specific vehicle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-In EMI Filter:\u003c\/strong\u003e Eliminates radio frequency interference — a common issue when converting from HID to LED — without additional inline components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Year Warranty:\u003c\/strong\u003e Heise backs the Pro Series with a 3-year warranty — one of the strongest coverage periods in the aftermarket LED headlight category.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eInstallation \u0026amp; Fitment Recommendations\u003c\/h2\u003e\n\u003cp\u003eThe HE-D3CPRO is a direct plug-and-play replacement for D3S, D3R, and D8S HID bulbs. Before installing, rotate the collar to align the LED chip correctly for your housing type — horizontal orientation (chip parallel to the ground) for reflector housings, or per your projector housing's alignment guide for projector applications. Because this kit replaces a factory HID\/Xenon system, your vehicle's ballast will not be used — the HE-D3CPRO connects directly to the vehicle's wiring harness. If your vehicle's CANBUS system triggers a warning light after installation, a CANBUS adapter may be required. The built-in EMI filter handles interference in the vast majority of HID-to-LED conversion applications without additional components.\u003c\/p\u003e\n\n\u003ch2\u003eFull Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHeise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eHE-D3CPRO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBulb Fitment\u003c\/td\u003e\n\u003ctd\u003eD3S, D3R, D8S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrightness\u003c\/td\u003e\n\u003ctd\u003e16,000 Lumens (per set)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e70W per set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e12–24V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e46.1°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCore Material\u003c\/td\u003e\n\u003ctd\u003e2 mm Solid Copper Thermodynamic Core\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing Construction\u003c\/td\u003e\n\u003ctd\u003eAll-Metal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermal Management\u003c\/td\u003e\n\u003ctd\u003eHigh-Speed Smart Fan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Adjustment\u003c\/td\u003e\n\u003ctd\u003eFully Rotatable Collar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEMI Protection\u003c\/td\u003e\n\u003ctd\u003eBuilt-In EMI Filter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePolarity Protection\u003c\/td\u003e\n\u003ctd\u003eBuilt-In Reverse Polarity Protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e3 Years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEstimated Weight\u003c\/td\u003e\n\u003ctd\u003e0.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the HE-D3CPRO work with my factory HID ballast?\u003c\/strong\u003e\u003cbr\u003eNo — the HE-D3CPRO bypasses the factory HID ballast entirely and connects directly to your vehicle's wiring harness.
