The **L3CK-51-R** is a specific part number typically associated with automotive lighting components, specifically for the **Mazda 3 (2010–2013)** series. It refers to the **Front Right (Passenger Side) Fog Light / Driving Light Assembly**. Below is a detailed breakdown of its electronic and structural characteristics. --- ### Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Front Fog Lamp Assembly | | **Placement** | Front, Right Side (RH) | | **Bulb Type** | Typically H11 (Halogen) | | **Operating Voltage** | 12V DC (Standard Automotive) | | **Wattage** | 55W (Standard H11) | | **Lens Material** | Clear Glass or High-Impact Polycarbonate | | **Housing Material** | Heat-resistant ABS Plastic | --- ### Electronic Components & Functionality #### 1. The Light Source (H11 Bulb) The primary electronic element is the H11 bulb. It uses a tungsten filament enclosed in halogen gas. When current flows through the filament, it heats up to incandescence, providing a focused, low-angled beam designed to cut through fog or rain without reflecting back into the driver's eyes. #### 2. Electrical Connector The assembly features a standard automotive two-pin socket (H11 interface). * **Pin 1 (Positive):** Connects to the fog light relay/switch. * **Pin 2 (Ground):** Connects to the vehicle chassis or negative battery terminal. #### 3. Reflector Optics While not "electronic" in the sense of a circuit, the internal parabolic reflector is mathematically designed to work with the specific filament position of the bulb to ensure the light pattern adheres to SAE/DOT safety regulations. #### 4. Thermal Management Since 55W halogen bulbs generate significant heat, the assembly includes: * **Venting:** Small Gore-Tex or mesh breathers that allow moisture to escape while preventing water from entering. * **Heat Shielding:** Internal metal components to prevent the plastic housing from melting during prolonged use. --- ### Compatibility & Context This part is specifically engineered for the **Mazda 3** models (including the Hatchback and Sedan) produced between **2010 and 2013**. It is an OEM (Original Equipment Manufacturer) specification part, meaning it is designed to fit the factory harness without modifications. ---
