If you're building a realistic scale rig, setting up a night-time bashful track session, or wanting to add visual flair to your RC display collection, this LED unit set offers tremendous value and reliability. The Killer Body brand is trusted by RC enthusiasts throughout the United Kingdom and internationally for producing durable, fit-for-purpose lighting and detail upgrades.

Key Features

• 17 Individual 3mm LEDs in Multiple Colours — The set includes six yellow lights, nine white lights and two red lights, giving you complete flexibility to customise your RC car or truck's lighting layout exactly as you envision it. Yellow lights work beautifully for side marker lights and indicator positions, white lights are ideal for headlamps and reverse lights, and red lights suit tail lights and brake light applications.
• Killer Body LED Control Box II — The dedicated control box is engineered specifically to manage the power distribution and switching for all 17 LEDs simultaneously. This intelligent control system ensures consistent brightness, protects your RC's electrical system from overload, and allows straightforward on-off switching integrated directly into your vehicle's power system.
• Two Y Connecting Wires Included — These wires enable easy parallel wiring of multiple LED circuits, allowing you to group and control different lighting sections (for example, front lights on one circuit and rear lights on another). This flexibility means you can create sophisticated lighting patterns that respond to your vehicle's operation.
• 3mm Diameter Size — The 3mm LED form factor is the standard specification across the RC hobby, ensuring compatibility with the vast majority of RC shells, light buckets and body mounting points available for 1/10 scale vehicles. This size has been proven in the field and is widely supported by aftermarket shell manufacturers.
• Professional Installation Design — The system is engineered for straightforward installation without requiring advanced soldering skills or complex wiring modifications. The included instruction sheet provides clear guidance on integrating the LEDs and control box into your RC setup.
• Suitable for 1/10 Scale RC Vehicles — Killer Body have specifically engineered this LED set for the 1/10 scale market, which represents the most popular and widely-used RC vehicle scale in the United Kingdom. Compatibility is confirmed with standard 1/10 RC cars, 1/10 RC trucks and the Killer Body 1/10 Marauder II.
• Complete Ready-to-Use Solution — Unlike piecemeal LED kits that require you to source additional components, this set includes everything necessary: the control box, the LEDs themselves, connecting wires and documentation. You're not left searching for compatible parts or wondering how to integrate disparate components.

Technical Performance

The KILLERBODY LED UNIT SET demonstrates solid engineering principles throughout its design. The 3mm LED standard is recognised across the RC industry as the optimal balance between brightness, power consumption, heat generation and physical size for 1/10 scale applications. The Killer Body LED Control Box II is engineered to handle the power distribution requirements of all 17 LEDs simultaneously, protecting both the LED units and your RC vehicle's main battery and electrical system from potential overload conditions. The 3mm form factor allows these LEDs to fit into purpose-designed light buckets and lens assemblies that come pre-moulded into many modern RC shells and bodywork designs.

The colour selection — six yellow, nine white and two red — reflects practical considerations developed through extensive use in the RC community. Yellow lights provide excellent visibility for side markers and indicators whilst maintaining a realistic scale appearance. White lights deliver maximum illumination for headlamp positions and offer versatile mounting options throughout your build. Red lights are optimised for brake light and tail light applications where lower intensity and distinct colour differentiation are priorities. The included Y connecting wires enable flexible circuit routing, allowing you to wire front and rear lighting circuits independently or in combination depending on your design preferences and the capabilities of your RC vehicle's receiver and power distribution system.

Frequently Asked Questions

• Is the KILLERBODY LED UNIT SET KB48735 suitable for beginners new to RC lighting? — Yes, absolutely. This is one of the most accessible LED kits for 1/10 scale RC builds. The Killer Body LED Control Box II handles all the complex power management automatically, and the included Y connecting wires simplify wiring considerably compared to building custom LED circuits from scratch. The instruction sheet provides straightforward guidance, and the 3mm LED standard means you're working with proven, forgiving components. If you can identify positive and negative power connections on your RC receiver or battery, you can install this kit.
• What's the difference between the 3mm LED size and other LED options for RC cars? — The 3mm diameter is the industry standard for 1/10 scale vehicles because it provides an excellent balance of brightness, power consumption and physical size. Smaller LEDs (like 2mm or SMD components) deliver insufficient brightness for realistic scale lighting effects, whilst larger LEDs (5mm and above) are too physically large to fit within the light buckets and lens assemblies moulded into most modern RC shells. The 3mm size has been refined over years of RC hobby development and represents the optimised choice for your build.
• Can I use the KILLERBODY LED UNIT SET KB48735 with any 1/10 RC car or truck? — The set is specified as compatible with any 1/10 scale RC car or truck, with explicit confirmation of compatibility with the Killer Body 1/10 Marauder II. Most modern 1/10 scale shells and bodywork from mainstream manufacturers include pre-moulded light bucket positions designed for 3mm LEDs, so fitment is typically straightforward. If you're using an older or custom shell, verify that your body has light bucket positions suitable for 3mm components before ordering.
• How many lighting circuits can I create with this set? — The included two Y connecting wires allow you to create multiple independent lighting circuits. A common configuration uses one circuit for front lighting (headlamps and markers) and another for rear lighting (tail lights and brake lights), allowing you to control these sections independently. The Killer Body LED Control Box II manages power delivery to all circuits, but your RC receiver or auxiliary controller handles the switching and timing of when each circuit activates.
• What battery do I need to power the KILLERBODY LED system? — The LED control box integrates with your existing RC vehicle's battery system. Standard 1/10 RC cars and trucks use 2S LiPo batteries (7.4V nominal), 3S LiPo batteries (11.1V nominal) or similar systems. The control box is engineered to operate safely with the standard battery voltages used in the 1/10 RC scale. No additional battery is required unless you choose to install a dedicated auxiliary battery for lighting independence from your main drive system — a consideration for advanced builders only.
• Does this LED set require soldering? — Basic soldering skills are helpful but not strictly essential. The kit is designed to minimise soldering requirements through the use of pre-wired LEDs and the Y connecting wires. The instruction sheet clarifies exactly which connections require soldering and which can be made through alternative methods. For first-time installers uncomfortable with soldering, connecting directly to your RC receiver's power rails or using a simple battery connector system is a viable approach that many hobbyists employ.
• How bright are the 3mm LEDs in this set? — The 3mm LEDs in this Killer Body set are optimised for scale realism rather than maximum brightness. This means they're bright enough to be visible and effective in evening or indoor lighting conditions, and they provide realistic illumination appropriate to 1/10 scale proportions. They won't overwhelm your eyes like bright 5mm LEDs, making them perfect for detailed scale rigs where authenticity matters as much as visibility.
