Take full control of your lighting setup with the STEDI™ 4 Output Plug & Play Smart Harness™ — the heavy-duty twin-relay solution purpose-built for running up to four auxiliary driving lights from a single high beam trigger.
This harness is essentially two of our proven dual-output Smart Harnesses merged into one clean, integrated loom. That means double the relays, double the DT-P outputs, and enough current handling to comfortably power quad lightbar or spotlight configurations — all while maintaining full compatibility with even the most complex vehicle electrics.
Features:
- Built-in Microprocessor: Automatically detects positive and negative switched systems — no guesswork, no modification required.
- High Beam Trigger Integration: Plug & Play with HB3 and H4 adaptors included. No cutting, soldering or tapping required.
- 4x DT-P Outputs: Power up to four driving lights with native DT-P connectors, or use the included reducers for DT compatibility.
- Twin Relay Architecture: Two 80A relays and two 45A fuses handle high current draw with ease, ensuring reliable, isolated performance for each circuit.
- Waterproof Illuminated Switch: Low-profile dime-size switch with red backlighting — suits open cabin installs.
- ADR Compliant: Fully compliant when installed correctly — trigger lights only on high beam, with switch acting as an isolator.
- Durable Construction: 10AWG high-current cable, ribbed loom protection, heat shrink-wrapped relay connections — built for Aussie conditions.
