ULO 1004001 Combination Rearlight

The ULO 1004001 Combination Rearlight is a meticulously engineered lighting solution designed to enhance the rear illumination of Mercedes-Benz vehicles, particularly models within the C-Class and W203 series. Its dual-function design integrates both a standard tail light and a brake light into a single unit, providing a streamlined aesthetic while maintaining optimal visibility for drivers and oncoming traffic.

Key Features

• Dual-Functionality: Combines the rear light and brake light into one compact assembly, reducing the number of separate components required on the vehicle.
• High-Intensity LED Technology: Utilizes advanced LED elements that deliver bright, clear illumination with a long service life, ensuring consistent performance over many years.
• Precision Alignment: Engineered to match the original factory specifications for Mercedes-Benz models such as the C-Class (W203) and S-Class (S203), guaranteeing proper fitment and alignment within the vehicle’s rear panel.
• Durable Construction: Features a robust housing that resists impact, vibration, and environmental factors like moisture and temperature fluctuations.
• Compliance with Automotive Standards: Meets stringent European Union (EU) lighting regulations, ensuring safety and legality for road use across the continent.

Compatibility Overview

The ULO 1004001 Combination Rearlight is specifically tailored to fit a range of Mercedes-Benz models. Below is an organized list of compatible vehicle types, grouped by model series and year:

For each of these models, the rearlight is available in both left and right configurations, ensuring full compatibility with vehicles that require a symmetrical lighting setup.

Installation Guidelines

1. Preparation: Disconnect the vehicle’s battery to prevent electrical shock or accidental activation of the lighting system during installation.
2. Removal of Existing Unit: Carefully detach the current rearlight assembly by loosening the mounting screws and gently pulling the unit away from the rear panel. Note any wiring harness connections for later reattachment.
3. Mounting the New Rearlight: Position the ULO 1004001 Combination Rearlight into place, aligning it with the factory mounting points. Secure it using the supplied screws and torque specifications to ensure a firm fit.
4. Electrical Connection: Reconnect the wiring harnesses, ensuring that the brake light circuit is properly linked to the vehicle’s braking system. Verify polarity and continuity before proceeding.
5. Testing: Restore battery power and test all functions—tail light, brake light, turn signals (if applicable), and any integrated hazard or parking lights—to confirm correct operation.

Performance Characteristics

The ULO 1004001 Combination Rearlight delivers exceptional performance metrics that align with modern automotive safety expectations:

• Brightness: LED output of approximately 2,500 lumens for the brake light and 1,200 lumens for the tail light.
• Luminous Efficiency: Energy consumption of roughly 5 watts per unit, significantly lower than traditional incandescent bulbs.
• Color Temperature: Warm white (3,000–4,000 K) to match the vehicle’s original lighting palette while providing clear visibility.
• Operating Life: Estimated 30,000 hours of continuous use before significant dimming occurs.

Design and Aesthetic Integration

The rearlight’s sleek profile is crafted to blend seamlessly with the vehicle’s rear fascia. Its matte finish resists glare, while the integrated reflector system ensures that light is directed precisely where it is needed—toward oncoming traffic and pedestrians. The design also accommodates optional aftermarket accessories such as fog lamps or additional lighting modules without compromising structural integrity.

Maintenance Tips

To preserve optimal performance, follow these simple maintenance practices:

• Inspect the unit annually for signs of physical damage or corrosion.
• Clean the lens and housing with a mild detergent solution; avoid abrasive cleaners that could scratch the surface.
• Check electrical connections for tightness and integrity, especially after exposure to harsh weather conditions.
• Replace any faulty LEDs promptly to prevent uneven lighting or reduced visibility.

Conclusion

The ULO 1004001 Combination Rearlight stands out as a reliable, high-performance component that enhances both the safety and visual appeal of Mercedes-Benz vehicles. Its thoughtful integration of dual lighting functions, adherence to stringent automotive standards, and compatibility across multiple model years make it an essential upgrade for owners seeking durability and precision in rear illumination.
