ULO 1059001 Combination Rearlight

ULO 1059001 Combination Rearlight

The ULO 1059001 Combination Rearlight is a meticulously engineered lighting solution designed for modern automotive applications. It seamlessly integrates multiple illumination functions—daytime running lights, brake lights, turn signals, and a reverse indicator—into a single, compact assembly. This integration not only reduces weight but also simplifies the vehicle’s electrical architecture.

Design and Construction

The rearlight features a robust polycarbonate housing that protects the internal components from environmental stresses such as moisture, vibration, and temperature extremes. The housing is finished with a high‑gloss black coating, providing both aesthetic appeal and resistance to UV degradation. The front face is fitted with a precision‑milled lens that ensures optimal light dispersion and compliance with international safety standards.

Optical Performance

At the heart of the ULO 1059001 lies a set of advanced LED modules. These LEDs are selected for their high luminous efficacy, typically exceeding 120 lumens per watt, and a long service life of over 50,000 hours. The light distribution pattern is engineered to provide a uniform illumination across the rear of the vehicle, enhancing visibility for following drivers while maintaining compliance with regulatory glare limits.

Electrical Integration

The rearlight is designed to interface with a vehicle’s existing electrical system via a standard 4‑pin connector. The pins correspond to the following functions:

• Pin 1: Daytime Running Light (DRL) input
• Pin 2: Brake Light activation
• Pin 3: Turn Signal (left/right) input
• Pin 4: Reverse Light signal

A built‑in current limiting circuit protects the LEDs from overcurrent conditions, ensuring reliability and safety. The module also incorporates a temperature sensor that dynamically adjusts brightness to maintain optimal performance across a wide temperature range.

Installation and Compatibility

The ULO 1059001 Combination Rearlight is engineered for straightforward installation in a variety of vehicle models. Its dimensions—approximately 120 mm × 70 mm × 30 mm—fit within standard rearlight housings, and the mounting brackets are designed to accommodate both front‑mounted and rear‑mounted configurations. The module is compatible with a broad spectrum of automotive platforms, including sedans, coupes, and compact cars.

Compliance and Standards

This rearlight meets or exceeds the following regulatory requirements:

• UNECE Regulation No. 48 – Safety requirements for rear lighting units.
• ISO 21384 – Standard for automotive lighting systems.
• UL 9245 – Safety standard for automotive lighting.
• ECE R48 – European safety regulations for rear lighting.

The product’s compliance with these standards guarantees that it delivers reliable performance in diverse driving environments.

Maintenance and Longevity

The ULO 1059001 Combination Rearlight is designed for minimal maintenance. The sealed LED modules eliminate the need for bulb replacements, and the robust housing resists corrosion and physical impact. Routine checks should focus on ensuring that the electrical connections remain secure and that the lens remains free of debris or scratches.

Environmental Impact

By consolidating multiple lighting functions into a single unit, the ULO 1059001 reduces overall vehicle weight and material usage. The LEDs consume significantly less power than traditional incandescent or halogen bulbs, contributing to lower fuel consumption and reduced greenhouse gas emissions. Additionally, the module’s long service life minimizes electronic waste.

Conclusion

The ULO 1059001 Combination Rearlight exemplifies modern automotive lighting technology. Its compact design, superior optical performance, and stringent compliance with safety standards make it an ideal choice for vehicle manufacturers seeking to enhance rear visibility while simplifying assembly and reducing environmental impact.
