Heise H3 Pro Series LED Kit - Single Beam

The Heise H3 Pro Series LED Kit (HE-H3PRO) turns night into day with an astonishing 16,000 lumens of crisp white light — dramatically brighter than stock halogen H3 bulbs — in a direct plug-and-play single-beam format. Commonly used in fog light and auxiliary light applications on trucks, SUVs, and off-road rigs, the H3 Pro Series is built for enthusiasts who demand maximum visibility from every light position on their build. 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 fog light housings. Instant full-power illumination right when you need it — no warm-up, no flicker, no compromise.

Running at 70W per set, the H3 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 under sustained use. The fully 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. The integrated EMI filter keeps your radio, GPS, and CB completely static-free. Backed by a 3-year limited warranty, this is the H3 LED upgrade that serious off-road enthusiasts have been waiting for.

The H3 Pro Series fits any vehicle running an H3 single-beam socket — a fitment commonly found in fog light and auxiliary light positions on a wide range of trucks, SUVs, Jeeps, and off-road 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 on high-draw or older wiring applications for maximum output and longevity.

Why Choose the Heise H3 Pro Series LED Kit?

• 16,000-Lumen Output: Dramatically brighter than stock halogen H3 bulbs for maximum fog light and auxiliary light 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: 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 alignment in projector or reflector fog light housings.
• Slim Side-Cable Connection: Clean, compact connector fits tight fog light housings without modification.
• Built-In EMI Filter: Eliminates radio static and interference — critical for rigs running CB, ham radio, or GPS systems.
• 3-Year Limited Warranty: Heise stands behind the H3 Pro Series with one of the strongest warranties in the LED lighting segment.

Installation & Compatibility Recommendations

The Heise H3 Pro Series installs directly into any H3 socket with no modifications required in most vehicles. The single-beam design is a true drop-in replacement for H3 fog light and auxiliary light applications. For vehicles with CANBUS error detection (common on European platforms and some newer trucks and crossovers), 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 to confirm proper beam pattern before driving.

Frequently Asked Questions

What amp rating do I need for the Heise H3 Pro?
The H3 Pro draws 70W per set (35W per bulb), roughly 5.8A per bulb at 12V. Factory H3 fog light 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 H3 Pro for daily driving?
The H3 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 H3 Pro work in my projector fog light housing?
Yes — the rotatable collar allows you to adjust the LED chip orientation for proper beam alignment in both projector and reflector fog light housings.

Do I need a CANBUS decoder?
On most older trucks, Jeeps, and off-road platforms with H3 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.
