Szdystar LED Lights Bar Remote Wiring Harness Kit – 12V/24V, 40A Relay, 3.5m

Overview

The Szdystar LED Lights Bar Remote Wiring Harness Kit provides a compact, DIY-friendly way to power and control a single LED bar with a wireless switch. By default it runs on 12V systems, and it can handle 24V vehicles when you swap in the appropriate relay. Thoughtfully designed for on-the-road or off-road use, it helps you manage lighting with a simple press or from up to 30 meters away.

Key features at a glance

• DC12V/24V compatibility with a relay swap for 24V installations
• 3.5 m (11.48 ft) cable length using 14 AWG copper core wire
• 40A blade fuse and built-in relay for safe, reliable power control
• On-off switch with a keyboard-style tactile feel for easy placement
• Remote control with approximately 30 m range and six lighting modes
• Universal plug and weather-resistant construction for durability

Wide compatibility and practical use

This harness is designed for a broad range of 12V lighting options, including LED bars, off-road lights, fog lights, work lights, and other 12V accessories. You can pair it with halogen, HID, or LED driving lights and drive additional lighting configurations as your setup evolves. The kit emphasizes straightforward wiring so you can enjoy a clean install without altering the vehicle’s original harness.

How it works

Mount the harness near the battery, connect to the LED bar, and place the switch wherever it’s most convenient. The remote control supplies six pattern options, letting you tailor brightness and beam behavior to different driving conditions. The system is designed so the power path remains isolated from the vehicle’s main harness, helping reduce wear on existing circuits.

Important notes: professional installation or guidance is recommended, and ensure your wiring matches the correct operating voltage. The device supports a maximum single-lamp load up to 300 W; using 12V in routine operation can contribute to longer-term reliability. If you have a 24V system, remember to replace the relay with a 24V version.
