HEISE LED Lighting Systems

<h3>About HEISE LED Lighting Systems</h3><p>HEISE LED Lighting Systems is a flagship brand under <strong>Metra Electronics</strong>, one of the most trusted names in aftermarket vehicle accessories with more than 75 years of innovation behind it. <a href="/13924-heise-led-lighting-systems">Launched in 2014</a>, HEISE quickly rose to prominence by engineering high-performance LED lighting solutions that are held to an exceptionally rigorous standard — one the brand sums up with a simple promise: <em>torture tested</em>.</p><p>What sets HEISE apart from the competition is not just the quality of the light output, but the relentless durability testing baked into every product's development cycle. HEISE lights are frozen, cut in half, submerged, shaken, and even shot before they ever leave the factory. Every unit also undergoes a final round of quality inspection before shipping, ensuring that customers receive lights capable of performing in the harshest real-world conditions — whether that means a muddy off-road trail at midnight or the bow of a boat in heavy seas.</p><h3>Engineering That Goes the Distance</h3><p>HEISE products are exclusively developed and manufactured to meet all international standards. The lighting lineup integrates advanced thermal management along with short-circuit and open-circuit protection — engineering details that directly extend the working life of each fixture. Die-cast aluminum housings, polycarbonate lenses, and military-grade breather valves appear across the product range, reflecting a commitment to materials that hold up under pressure rather than just look good on a spec sheet.</p><p>The brand's extensive catalog spans <a href="/13924-heise-led-lighting-systems-light-bar-1069">LED light bars</a>, cube lights, auxiliary driving lights, accent and RGB underglow kits, replacement LED headlight bulbs, marine-grade lighting, trailer and municipality lights, and Jeep-specific lighting accessories. This breadth means that whether you are building out a rock-crawling rig, outfitting a commercial work truck, or adding accent lighting to a powersports machine, HEISE has a purpose-built solution ready to install.</p><h3>Built for Off-Road, Work, and Beyond</h3><p>HEISE light bars are among the brand's most celebrated products, available in single-row, dual-row, curved, and RGB backlit &quot;Infinite Series&quot; configurations across a wide range of lengths. Their hybrid beam pattern combines intense center spotlights with flanking wide-beam flood lights, giving drivers exceptional illumination depth and spread simultaneously. The bars are backed by a limited lifetime warranty — a testament to how confident HEISE is in its own manufacturing quality.</p><p>Beyond off-road applications, HEISE serves boaters with marine-grade fixtures torture-tested to withstand saltwater exposure, first responders and construction crews with its Municipality Series strobe and marker lights, and Jeep enthusiasts with a dedicated line of model-specific lighting upgrades. The <strong>Heise Connect</strong> ecosystem ties many of these products together, allowing users to control RGB and chasing LED installations through a free mobile app for a fully customizable lighting experience.</p><h3>Why Choose HEISE?</h3><ul><li>Designed and manufactured to international quality standards by Metra Electronics</li><li>Advanced thermal management and electrical protection built into every fixture</li><li>Torture-tested construction using die-cast aluminum, polycarbonate lenses, and sealed housings</li><li>Limited lifetime warranty on light bars</li><li>Wide application coverage: off-road, marine, powersports, Jeep, work, and municipality</li><li>Heise Connect app ecosystem for RGB and chasing LED control</li></ul>

Product Details

The HEISE HE-SLWH1 is a universal plug-and-play wiring harness and switch kit designed to power a single LED light bar or cube light with a DT-style connector. Everything needed for a clean, straightforward installation is included in the kit, making it an ideal solution for off-road, marine, and powersports lighting setups.

The harness features a 9-foot lead for the light bar connector, providing enough reach for most mounting locations. A built-in 12V DC relay and 30-amp fuse protect the circuit, while the waterproof fuse holder ensures reliable performance in harsh environments. Control is handled by the included on/off rocker switch, which mounts easily in the cab or console.

Key Features:

  • Universal plug-and-play wiring harness for 1 lamp with DT connector
  • 9 ft lead for light bar connector
  • Includes on/off rocker switch
  • 12V DC relay for circuit protection
  • 30A fuse with waterproof fuse holder

The HE-SLWH1 is compatible with HEISE light bars 22 inches or smaller and all HEISE cube lights, provided the fixture draws 150 watts or less. For installations requiring two lamps, see the HEISE 2-lamp wiring harness kit.
