Welcome to the premium Sinotruk Sitrak parts collection. Our Sitrak Rear Combination Lamp with Seven Functions is an advanced lighting assembly designed to ensure maximum visibility, safety, and compliance for heavy-duty trucks. This integrated lamp unit combines multiple critical lighting functions into a single, robust housing, providing a reliable and durable solution for the rear of your SINOTRUK Sitrak vehicle. Engineered to meet stringent international standards, it enhances road safety for your truck and other motorists in all driving conditions.
The Sitrak Rear Combination Lamp with Seven Functions is a comprehensive lighting assembly that integrates multiple essential rear lighting signals into one durable unit for heavy-duty trucks. This lamp is a critical safety component, designed to communicate the truck’s intentions and presence to other drivers on the road. It consolidates seven distinct lighting functions, eliminating the need for multiple separate lamps and simplifying the vehicle’s electrical system and bodywork. The assembly is specifically designed as a direct replacement or upgrade for SINOTRUK Sitrak trucks, ensuring perfect fitment and compatibility.
The seven functions typically include tail lights, brake lights, turn signals (indicators), reverse lights, rear fog lights, and side marker lights. The integration of a side marker light is a key feature, providing essential lateral visibility to vehicles approaching from the side or at intersections, significantly enhancing safety during nighttime operations or in low-visibility conditions. Each function uses high-intensity LEDs or robust filament bulbs designed for long life and reliable performance under constant vibration and harsh weather conditions.
The lamp housing is constructed from high-impact-resistant materials, such as polycarbonate or durable ABS plastic, which can withstand stone chips, UV radiation, and extreme temperatures without cracking or fading. The lens is precisely molded with clear and colored segments to differentiate between the various functions while maximizing light output. The assembly is designed to be waterproof and dustproof, with integrated seals and gaskets to protect the electrical connectors and bulbs from moisture and corrosion, which is vital for maintaining functionality in all weather conditions.
This product is sold as a complete kit, including both left and right-hand lamp assemblies and the necessary Type 1 all-metal hexagon lock nuts for secure mounting. The lock nuts are made from high-grade metal to resist rust and ensure the lamps remain firmly attached to the vehicle’s body despite constant vibration from road travel. By choosing this genuine SINOTRUK part, operators ensure their vehicle meets legal lighting requirements, enhances safety, and maintains the original equipment’s quality and reliability.

Comprehensive Safety Integration: Our seven-function lamp consolidates all critical rear signals into one reliable unit, ensuring your truck communicates effectively with following traffic.
