Heise Pro Series LED Bulbs - Fits D3S, D3R, D8S

The Heise Pro Series HE-D3CPRO is a high-output LED replacement for D3S, D3R, and D8S HID bulb fitments, delivering a blinding 16,000 lumens per set at just 70 watts total — 260% brighter than standard LED replacements — while running on a wide 12–24V DC operating voltage that makes it compatible with both standard 12V passenger vehicles and 24V commercial or heavy-duty applications. Built around an extreme-grade LED chipset in an all-metal housing, the HE-D3CPRO is engineered for enthusiasts and professionals who need maximum light output, long-term thermal reliability, and a clean, interference-free install when replacing factory HID systems with modern LED technology.

Heise's thermal management system is the engineering highlight of the Pro Series. A 2 mm solid copper thermodynamic core paired with a high-speed smart fan keeps operating temperatures at just 46.1°C — far below the thermal thresholds that cause LED degradation and output loss in lesser kits. A fully rotatable collar allows precise beam alignment in both projector and reflector housings, ensuring a clean, properly aimed light pattern regardless of your vehicle's headlight housing design. The built-in EMI filter eliminates radio frequency interference that commonly causes static on AM/FM, DAB, and other vehicle electronics when switching from HID to LED, and reverse polarity protection prevents bulb damage from incorrect wiring during installation. Backed by a 3-year warranty, the HE-D3CPRO is built to last.

At Trinity Car Audio, the Heise Pro Series D3S/D3R/D8S LED kit is the recommended upgrade for vehicles equipped with factory Xenon HID lighting systems that use D3S, D3R, or D8S bulb fitments. 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. Note: Always verify local regulations regarding LED headlight replacements before installing on street-driven vehicles.

Why Choose the Heise Pro Series HE-D3CPRO?

• Fits D3S, D3R & D8S: 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.
• 16,000 Lumens Per Set: 260% brighter than standard LED replacements — dramatically more light output than the factory HID bulbs being replaced in most applications.
• 12–24V DC Operating Range: Compatible with standard 12V passenger vehicles and 24V commercial or heavy-duty applications — one kit covers a broad range of vehicle types.
• 2 mm Solid Copper Thermodynamic Core: Superior heat dissipation versus aluminum-core competitors, maintaining consistent output at just 46.1°C operating temperature.
• High-Speed Smart Fan: Active cooling prevents thermal throttling and maintains full-brightness output across the bulb's lifespan — no output degradation over time.
• Fully Rotatable Collar: Precise beam alignment for projector and reflector housings ensures a clean cutoff line and optimal light projection for your specific vehicle.
• Built-In EMI Filter: Eliminates radio frequency interference — a common issue when converting from HID to LED — without additional inline components.
• 3-Year Warranty: Heise backs the Pro Series with a 3-year warranty — one of the strongest coverage periods in the aftermarket LED headlight category.

Installation & Fitment Recommendations

The 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.

Frequently Asked Questions

Does the HE-D3CPRO work with my factory HID ballast?
No — the HE-D3CPRO bypasses the factory HID ballast entirely and connects directly to your vehicle's wiring harness. The ballast is not used in this conversion. If your vehicle's system triggers a fault code after removing the ballast, a CANBUS adapter may be required.

Will this kit trigger a CANBUS warning light?
It depends on your vehicle. The HE-D3CPRO includes a built-in EMI filter but does not include a CANBUS adapter. If your vehicle displays a bulb-out or system warning after installation, a separate CANBUS adapter is recommended. Check your vehicle's compatibility before ordering.

How do I align the beam pattern after installation?
Rotate the collar on each bulb so the LED chip sits horizontally (parallel to the ground) for reflector housings. For projector housings, follow your housing's specific alignment guide. Correct chip orientation is critical for a clean cutoff line and proper beam projection.

What vehicles use D3S, D3R, or D8S bulbs?
D3S and D3R fitments are common in European vehicles including BMW, Mercedes-Benz, Audi, Volkswagen, and Porsche, as well as many Japanese models from Toyota, Lexus, and Nissan. D8S is a newer fitment found in select late-model vehicles. Always verify your specific vehicle's bulb fitment before ordering.
