Overview

The Traxxas LED light bar, Rear, Red (with amber class light) (high-voltage) is a professional-grade lighting component designed specifically for the Traxxas Unlimited Desert Racer (UDR) and other compatible RC vehicles. This rear brake and class light bar combines functional illumination with authentic scale realism, featuring 24 individual red LEDs and 24 amber LEDs housed within a compact 100mm wide assembly. Whether you're an experienced RC enthusiast running a high-end desert racer or someone exploring the world of scale RC trucks, this lighting solution transforms your vehicle into a truly realistic off-road machine.

This high-voltage LED light bar is part of Traxxas's revolutionary Pro-Scale LED lighting system, which represents a significant leap forward in RC vehicle customisation and scale detail. The UDR lighting ecosystem has been engineered from the ground up to deliver features and performance that simply aren't available on any other aftermarket lighting kit for RC cars and trucks in the UK market. With 204 individual LEDs distributed across the complete system and powered by Traxxas's proprietary high-voltage amplifier, the entire setup operates with unprecedented efficiency and reliability, ensuring your ready to run RC truck looks and performs like a genuine desert racing machine.

The rear light bar specifically serves dual functions: it operates as a genuine brake light that responds intelligently to your driving input, and it provides authentic amber class lighting to enhance the scale realism of your vehicle. This is not merely decorative lighting—it's functional illumination that mirrors how real desert racing trucks operate, adding an extraordinary level of authenticity to your RC experience.

Key Features

• 24 Red LEDs with 24 Amber LEDs — This combination provides both functional brake lighting and amber class lighting in a single elegant rear assembly, with the red LEDs activating when brakes are applied and the amber LEDs providing ambient class lighting for enhanced scale appearance and visibility during operation.
• High-Voltage Design — The high-voltage architecture taps power directly from your vehicle's battery through the power amplifier rather than drawing from the BEC (battery eliminator circuit), ensuring intense, brilliant lighting performance without compromising your vehicle's main power systems or reducing available throttle and steering power.
• Intelligent Brake Light Function — Unlike generic aftermarket RC lighting systems that often fail to distinguish between reversing and braking, this Traxxas system features smart brake lights that work when brakes are applied in both forward and reverse directions, delivering truly functional and realistic brake lighting behaviour that mirrors real vehicles.
• 100mm Wide Compact Design — The 100mm width provides optimal scale proportions for the UDR while remaining compact enough for clean installation without excessive overhang or vulnerability during off-road bashiing and rock crawling adventures.
• Fully Waterproof Construction — Every component is engineered to be completely waterproof and weatherproof, allowing you to run your RC vehicle through water crossings, desert dust storms, and challenging wet-weather conditions without concern for electrical failure or LED damage.
• Integration with 8-Channel Power Amplifier — This rear light bar works seamlessly with the included high-voltage 8-channel power amplifier that powers all 204 LEDs in the complete lighting system, providing regulated output and preventing flickering or dimming as battery voltage fluctuates during driving.
• App Control and Customisation — Compatible with the Traxxas Link wireless app system, you can control individual lighting components, turn lights on and off remotely, and create custom lighting configurations that suit your driving style and preferences.
• Multiple Brightness Settings — The system includes low and high beam brightness settings, allowing you to adjust lighting intensity for different conditions and preserve battery life when maximum illumination isn't necessary.
• Regulated Voltage Output — The high-voltage amplifier tightly regulates voltage to prevent flickering or dimming issues that plague budget lighting solutions, ensuring stable and consistent lighting performance throughout your battery's discharge cycle.

Technical Performance

The Traxxas LED light bar represents a quantum leap in RC lighting technology, engineered with the same precision and attention to detail that goes into the UDR platform itself. This rear assembly contains 48 individual LEDs (24 red and 24 amber) distributed across a 100mm wide light bar, delivering brilliant illumination that's bright enough to be visible in daylight conditions and genuinely useful for night-time operation. The high-voltage power architecture is particularly clever: rather than relying on a vehicle's standard ESC BEC output (which is typically limited to 2-3 amps and designed primarily for receiver and servo power), the system draws directly from the main battery pack through the power amplifier. This approach allows the amplifier to deliver sufficient current to drive all 204 LEDs in the complete system with full intensity whilst maintaining regulated, clean power that prevents the voltage fluctuations and flickering problems common in lesser lighting kits. The power amplifier transforms and regulates battery current specifically for LED operation, ensuring reliable high-power performance even as your LiPo battery voltage drops during discharge. Installation is straightforward—the main connector plugs directly into the power port on the Traxxas VXL-6s Electronic Speed Controller, and individual lighting modules including this rear bar plug into the power amplifier using colour-coded, concealed wiring that keeps your installation neat and professional-looking. The system is fully compatible with all modern brushless Traxxas platforms and can be controlled via three manual lighting modes on the power amplifier itself (such as high beam and low beam selections) or through the Traxxas Link app when paired with the optional wireless module, giving you complete flexibility in how you operate your lighting.

Frequently Asked Questions

• Is this rear light bar sold as a complete lighting system or as an individual component? — This rear light bar (TRX8487) is sold as an individual component, allowing UDR owners and enthusiasts to customise their lighting setup exactly as desired. The complete Traxxas Pro-Scale LED lighting system (TRX8485) includes dual bumper-mounted LED light bars, a curved roof light bar, this multifunction rear light bar, and the high-voltage 8-channel power amplifier, but you can purchase components separately to build your ideal configuration.
• What is the difference between the red and amber LEDs in this rear light bar? — The 24 red LEDs function as brake lights that illuminate when you apply brakes during forward driving, providing authentic functional lighting. The 24 amber LEDs provide class lighting, which is a standard feature on full-size desert racing trucks for identification and scale authenticity. Together, they create a realistic rear lighting setup that mirrors genuine desert racing vehicles.
• Can I use this rear light bar without the complete lighting system? — This rear light bar requires the high-voltage 8-channel power amplifier to operate, as it doesn't have its own independent power supply. The amplifier can be purchased separately (it's included in the complete TRX8485 lighting kit) and powers all LED components in the Traxxas system.
• Will this light bar work with my existing RC truck, or is it UDR-specific? — This light bar is specifically designed for the Traxxas Unlimited Desert Racer platform, with mounting hardware engineered for UDR compatibility. It may be possible to adapt it to other vehicles, but this would require custom fabrication and isn't recommended by Traxxas. The UDR represents the ideal platform for this lighting system.
• How do I control the red and amber LEDs separately? — The rear light bar integrates into the overall 8-channel lighting system, meaning you can control it through the power amplifier's manual modes or through the Traxxas Link app. The intelligent brake light function automatically distinguishes between braking and reversing, activating the red LEDs appropriately without requiring separate manual control for each colour.
• Is this waterproof for water crossings and desert washes? — Yes, this rear light bar is fully waterproof and weatherproof, engineered to handle water crossings, desert dust, mud, and challenging wet-weather conditions without electrical failure or LED damage. The sealed construction ensures water cannot infiltrate the LED assemblies or electrical connections.
• Can I use just the rear light bar, or do I need all the lights in the system? — You can use just the rear light bar as an individual component, but you'll need the high-voltage 8-channel power amplifier to power it. The system is expandable, allowing you to start with the rear bar and add front bumper bars or the roof light bar later as desired.
• How much does this rear light bar affect battery runtime? — The high-voltage amplifier architecture minimises power losses from excessive current and heat, ensuring efficient operation. However, adding 48 individual LEDs does consume additional battery power. The extent of runtime reduction depends on your battery capacity, driving style, and brightness settings selected. Using low beam brightness settings will preserve battery runtime compared to running high beam lighting throughout your session.
