HEISE 1 Lamp DR Wiring Harness & Switch Kit

The HEISE 1 Lamp DR Wiring Harness & Switch Kit is a universal plug-and-play electrical system designed to simplify the installation of HEISE LED light bars and cubes on boats and marine vessels. This single-lamp wiring harness kit eliminates the complexity of custom marine electrical work by providing a pre-assembled solution with all necessary components for safe, waterproof operation in saltwater environments.

The kit includes a 12V DC relay, 30-amp fuse housed in a waterproof fuse holder, an on-off rocker switch, and a 2-pin DT connector specifically configured for single-lamp applications. The 30-amp fuse rating matches the electrical demands of HEISE LED light bars and cube lights 22 inches or smaller, preventing overcurrent conditions while allowing full brightness output. The waterproof fuse holder addresses a critical consideration in marine electrical installations—saltwater corrosion and moisture ingress that can compromise standard fuse holders. The DT connector design ensures reliable, water-resistant connections that maintain integrity through repeated on-off cycling and exposure to spray and humidity.

This wiring harness is ideal for boat owners upgrading from incandescent to LED lighting systems, whether for deck illumination, cabin lights, or auxiliary spotlighting. Weekend fishermen adding a single light for night operation and offshore anglers installing tactical lighting systems both benefit from the standardized installation footprint. The kit eliminates the need to source individual relays, fuses, and connectors separately, reducing installation time and ensuring compatibility with HEISE LED products across recreational and professional marine applications.
