Key Features

• Six 3mm White LEDs — This system includes six individual 3mm white LEDs that deliver bright, eye-catching illumination. White LEDs provide authentic daytime running light appearance and excellent visibility during evening and night-time trail runs, making your RC vehicle immediately recognisable and genuinely impressive to watch in action.
• Extended Wire Length (815mm) — The primary wire length of 32 inches (815mm) gives you exceptional flexibility in routing power and control lines throughout your vehicle's chassis and body. This generous length means you can position the LED controller anywhere convenient and run wires to multiple light locations without awkward bends or compromises to your build layout.
• Servo Extension Wire Included (250mm) — A dedicated 9.8-inch (250mm) servo extension wire is included in the box, allowing you to extend control signals cleanly and professionally. This standard RC servo connection ensures simple integration with your existing transmitter and receiver setup without requiring any modifications or soldering.
• Wide Voltage Compatibility (4.5V–9V DC) — The system operates across a broad voltage range from 4.5 volts to 9 volts DC, making it compatible with most standard RC LiPo batteries and battery configurations. Whether you're running 2S, 3S, or similar battery packs, the RC4WD lighting system will perform reliably without additional voltage regulators or converters.
• Optimised Control and Operating Voltage (7.4V) — The system is specifically designed for 7.4-volt operation and control, which aligns perfectly with two-cell LiPo batteries (2S) commonly used in RC crawlers and trail trucks, ensuring predictable, stable performance across your fleet of RC vehicles.
• Lightweight Construction (13.3g) — Weighing just 0.46 ounces (13.3 grams), this lighting system adds virtually no weight penalty to your RC vehicle. This minimal mass means you maintain your rig's weight distribution, suspension response, and handling characteristics whilst enjoying the benefits of full-scale LED lighting.
• Designed for KC Light Sets — This system is engineered to work seamlessly with RC4WD's range of KC light sets, including rectangle lights with covers, KC HiLiTES models, and Daylighter variants. The integration ensures clean, professional results that match the aesthetic and quality standards of purpose-built RC4WD lighting kits.

Technical Performance

The RC4WD Basic LED Lighting System represents thoughtful engineering applied to a seemingly simple component. With six 3mm white LEDs and a carefully designed control circuit, this system delivers dependable illumination for scale RC applications. The wide DC voltage operating range of 4.5V to 9V ensures compatibility with diverse battery configurations, whilst the optimised 7.4V control and operating voltage provides stability when running standard 2S LiPo packs—the industry standard for RC crawlers and trail trucks in the UK market. The generous 815mm primary wire length and included 250mm servo extension cable demonstrate RC4WD's understanding of real-world RC builds, where flexible routing and clean integration are paramount. Construction quality reflects RC4WD's reputation as a manufacturer of scale-specific components; every element from the LED elements themselves to the control circuitry is built to survive the demands of off-road RC use, including vibration, temperature variation, and the occasional impact during trail runs. The featherweight 13.3-gram total package means you can add authentic lighting without the weight penalty that might otherwise affect suspension geometry or handling balance on challenging terrain.

What's in the Box

• 1x RC4WD Basic LED Lighting System for KC Light Set
• 1x Servo Extension Wire (250mm length)

Compatibility and Optional Upgrades

The RC4WD Basic LED Lighting System integrates with a comprehensive ecosystem of RC4WD lighting and control components. If you wish to add on/off control directly from your transmitter without affecting main power, the RC4WD Mini ON/OFF Switch for Lighting Unit (Z-E0081) is an ideal companion. For more dramatic lighting effects, the RC4WD Strobe Lighting Unit (Z-S1573) can be paired with this basic system for authentic emergency-style illumination. To expand your lighting configuration with additional light fixtures, RC4WD offers several compatible KC HiLiTES options, including Rectangle Lights with Covers (Z-E0132), the KC Light Set (Z-S1855), the Daylighter Light Set (Z-S1856), the KC Light Set V2 (Z-E0036), and the Daylighter Light Set V2 (Z-E0022). This modular approach lets you build custom lighting configurations tailored to your specific RC vehicle and personal preferences. The system has been proven on popular RC4WD platforms including the Trail Finder 2 LWB RTR with 1987 Toyota XtraCab Hard Body (Z-RTR0057), the Marlin Crawler Trail Finder 2 RTR with Mojave II Body (Z-RTR0034), and the Trail Finder 2 RTR with Chevrolet Blazer Body Rust Bucket Edition (Z-RTR0055).

Frequently Asked Questions

• Will this RC LED lighting system work with my standard 2S LiPo battery? — Yes, absolutely. The RC4WD Basic LED Lighting System is optimised for 7.4-volt operation, which is precisely the voltage delivered by a fully charged 2S LiPo battery (the most common battery configuration for RC crawlers and trail trucks in the UK). The system's broad 4.5V–9V DC operating range means it will function reliably across your entire battery discharge cycle.
• Is this lighting system suitable for beginners? — Yes, this is an excellent choice for those new to RC lighting upgrades. The system comes ready to install with no soldering or modifications required. Simply connect the servo extension cable to any spare channel on your receiver, and route the power and LED wires to your mounting location. The straightforward design and included extension cable make installation approachable for newcomers whilst remaining professional enough to satisfy experienced builders.
• How long are the wires and can I extend them further? — The primary wire run is 815mm (32 inches), which covers most RC vehicles from battery compartment to light mounting points. An additional 250mm (9.8 inches) servo extension cable is included for receiver connection. If you need even longer runs, standard RC servo extension cables are readily available from RC Model Shop and other UK retailers, and can be connected directly to the included connector.
• What is the difference between this Basic LED Lighting System and RC4WD's other lighting options? — The RC4WD Basic LED Lighting System provides the core LED controller and wiring harness, designed to work with separate RC4WD KC light sets. If you want an all-in-one solution with integrated light fixtures, RC4WD's complete KC HiLiTES Light Sets (such as Z-E0036 or Z-E0022) include both the controller and purpose-built light housings in a single package. This basic system is perfect if you're customising your lighting configuration or integrating with existing fixtures you already own.
• Is this waterproof or weather-resistant for muddy trails? — The basic LED system shares RC4WD's typical build quality standards for electronics, though complete waterproofing specifications are not detailed in the technical documentation. For maximum durability in wet or muddy conditions, consider housing the controller in a protective case or location within your RC vehicle, and ensure all connector joints are clean and dry before operation. Standard RC maintenance practices apply.
• How much weight does this add to my RC crawler? — At just 13.3 grams (0.46 ounces), this lighting system is virtually weightless in terms of RC vehicle performance. This minimal mass means you can upgrade your rig's visual appeal without compromising weight distribution, suspension balance, or handling on technical terrain.
