Heise 9004 Pro Series LED Kit - Dual Beam

The Heise 9004 Pro Series LED Kit (HE-9004PRO) lights up the darkest night trails with a dazzling 16,000 lumens of crisp white light — 260% brighter than stock halogen 9004 bulbs — in a direct plug-and-play dual-beam format. Built for trucks, SUVs, and off-road rigs running the 9004 (HB1) socket, this kit handles both high and low beam functions from a single bulb with zero compromises. An extreme LED chipset, all-metal housing, and 2 mm solid copper thermodynamic core keep operating temps locked at just 46.1°C, while a slim side-cable connection keeps the install clean in tight engine bays. Instantaneous full-lumen startup, integrated EMI shielding, and built-in reverse polarity protection round out a kit built for enthusiasts who demand the best.

Running at 70W per set, the 9004 Pro's IC thermal controller pairs with a high-speed smart fan to actively pull heat away from the diodes — extending LED life and maintaining consistent output even on the longest trail runs. The fully rotatable collar lets you fine-tune the beam pattern for perfect cutoff alignment in both projector and reflector housings, while the built-in EMI filter eliminates radio static and interference critical for rigs running CB, ham radio, or GPS systems. Backed by a 3-year warranty, this is the 9004 LED upgrade that serious off-road enthusiasts have been waiting for.

The 9004 Pro Series fits any vehicle running a 9004 / HB1 dual-beam socket — a common fitment across a wide range of domestic trucks and SUVs from the late 1980s through mid-2000s. 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 on high-draw or older wiring applications for maximum output and longevity.

Why Choose the Heise 9004 Pro Series LED Kit?

• 16,000-Lumen Output: 260% brighter than stock halogen 9004 bulbs for dramatically improved night visibility on and off the trail.
• Dual Beam (Hi/Lo): Handles both high and low beam functions from a single 9004 / HB1 bulb — true drop-in replacement.
• 70W Per Set: High-output power draw engineered for maximum lumen delivery without overloading factory wiring.
• 2 mm Solid Copper Thermodynamic Core: Efficiently pulls heat away from the LED chipset, extending bulb life and maintaining consistent output under sustained use.
• IC Thermal Controller + Smart Fan: Active cooling system keeps operating temps at just 46.1°C even during extended 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 running CB, ham radio, or GPS systems.
• 3-Year Warranty: Heise stands behind the 9004 Pro Series with one of the strongest warranties in the LED headlight segment.

Installation & Compatibility Recommendations

The Heise 9004 Pro Series installs directly into any 9004 / HB1 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. The slim side-cable connection keeps the install tidy in tight engine bays common on older domestic trucks and SUVs. For vehicles with CANBUS error detection (common on European platforms and some 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. 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 9004 Pro?
The 9004 Pro draws 70W per set (35W per bulb), roughly 5.8A per bulb at 12V. Factory 9004 wiring can typically handle this, but a relay harness is recommended for older vehicles or sustained high-use applications to protect factory connectors and maximize output.

Can I use the 9004 Pro for daily driving?
The 9004 Pro is labeled for off-road use only, as aftermarket LED 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 9004 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 and SUVs with 9004 sockets, no decoder is needed. If your vehicle has a CANBUS system that monitors bulb resistance, you may see a warning light or flickering — a CANBUS decoder resolves this instantly.
