Heise H4 Pro Series LED Kit - Dual Beam

The Heise H4 Pro Series LED Kit (HE-H4PRO) delivers a skull-rattling 16,000 lumens of pure white light — 260% brighter than stock halogen bulbs — in a direct plug-and-play H4 dual-beam format. Whether you're blasting down a dark trail or upgrading your daily driver's headlights, the H4 Pro Series is engineered to outperform, outlast, and outshine everything in its class. Built on an extreme LED chipset with an all-metal housing and a 2 mm solid copper thermodynamic core, this kit runs cool, starts instantly, and stays completely static-free thanks to integrated EMI shielding.

Under the hood, the H4 Pro runs at 70W per set and maintains a running temperature of just 46.1°C — a feat made possible by Heise's IC thermal controller paired with a high-speed smart fan that actively pulls heat away from the diodes. The rotatable collar lets you fine-tune the beam pattern for perfect alignment in both projector and reflector housings, while built-in reverse polarity protection means you can't wire it wrong. Backed by a 3-year warranty, this is a kit built for enthusiasts who demand performance without compromise.

The H4 Pro Series is compatible with any vehicle running an H4 (9003) bulb socket — including Jeeps, trucks, off-road rigs, and older domestic and import platforms. Installation is plug-and-play with no relay harness required in most applications. For vehicles with CANBUS systems or LED warning lights, a CANBUS decoder is recommended. Pair with a quality relay harness for maximum output and longevity on high-draw applications.

Why Choose the Heise H4 Pro Series LED Kit?

• 16,000-Lumen Output: 260% brighter than standard halogen H4 bulbs for dramatically improved night visibility on and off the trail.
• 70W Per Set: High-output power draw engineered for maximum lumen delivery without overloading factory wiring.
• 2 mm Solid Copper Thermodynamic Core: Pulls heat away from the LED chipset efficiently, extending bulb life and maintaining consistent output.
• IC Thermal Controller + Smart Fan: Active cooling system keeps operating temps at just 46.1°C even under sustained high-output use.
• Rotatable Collar: Dial in your exact beam pattern for proper cutoff alignment in projector or reflector housings.
• Built-In EMI Filter: Eliminates radio static and interference — critical for off-road rigs with CB, ham radio, or GPS systems.
• Reverse Polarity Protection: Foolproof installation — the kit protects itself if wired backwards.
• 3-Year Warranty: Heise stands behind the H4 Pro Series with one of the strongest warranties in the LED headlight segment.

Installation & Compatibility Recommendations

The Heise H4 Pro Series installs directly into any H4 / 9003 socket with no modifications required in most vehicles. The dual-beam design handles both high and low beam functions from a single bulb, making it a true drop-in replacement. For vehicles with CANBUS error detection (common on European platforms and newer trucks), add a CANBUS decoder to prevent flickering or error codes. On high-draw applications or older wiring, a relay harness is recommended to ensure the full 70W draw is sourced directly from the battery rather than through aging factory wiring. The rotatable collar should be adjusted after installation with the headlights aimed at a wall to confirm proper beam cutoff before driving.

Frequently Asked Questions

What amp rating do I need for the Heise H4 Pro?
The H4 Pro draws 70W per set (35W per bulb), which is roughly 5.8A per bulb at 12V. Your factory H4 wiring can typically handle this, but a relay harness is recommended for older vehicles or high-use applications to protect factory connectors and maximize output.

Can I use the H4 Pro for daily driving?
The H4 Pro is labeled for off-road use only, as aftermarket LED headlight kits are not DOT-certified for on-road use in the US. Many enthusiasts use them for off-road, overlanding, and trail driving where DOT compliance is not required.

Will the H4 Pro work in my projector headlight housing?
Yes — the rotatable collar allows you to adjust the LED chip orientation for proper beam cutoff alignment in both projector and reflector housings. Projector housings typically produce the cleanest beam pattern with LED bulbs.

Do I need a CANBUS decoder?
On most older trucks, Jeeps, and off-road platforms, no decoder is needed. If your vehicle has a CANBUS system that monitors bulb resistance (common on European vehicles and some newer trucks), you may see a warning light or flickering — a CANBUS decoder resolves this instantly.
