Key Features & Benefits​
Quick-Connect Installation​
Pre-Assembled Harness: Includes DT connectors (e.g., 2-pin, 4-pin) and color-coded wiring for tool-free setup—no soldering or factory wire splicing required .
Broad Compatibility: Works with common vehicle-specific adapters (e.g., HB3, H4) and popular lighting brands, supporting both positive and negative switched systems via an integrated microprocessor for automatic detection .
Rugged & Safe Construction​
IP68 Sealing: Fully sealed connectors and insulated wiring resist water, dust, and corrosion, ensuring performance in extreme environments .
High-Temperature Resilience: Operates from -40°C to 125°C, with flame-retardant PVC/XLPE insulation (UL94 V-0 rated) for enhanced safety .
Circuit Protection: Integrated relay and fuse safeguards (35A–60A) prevent overcurrent, short circuits, and voltage spikes .
High-Efficiency Electrical Performance​
Low Voltage Drop: 12–16 AWG tinned copper conductors minimize power loss, supporting loads up to 35A@12V (420W) for high-power LEDs .
Multi-Light Support: Capable of powering multiple lights simultaneously (e.g., light bars and spotlights) using DT/DTP connector layouts .
Customization & Scalability​
Flexible Configurations: Available in 2–4 pin DT variants with customizable lengths (0.5–10m) and OEM/ODM support for colors and branding .
Adapter Versatility: Includes piggyback adapters (HB3/H4) and DT-to-DTP converters for broad cross-compatibility .
