Product Specifications

I. Overview & Specialized Application
       The 880 (PG13) is a high‑wattage halogen bulb designed for auxiliary forward lighting applications, most notably in factory‑style fog lights, driving lights, and certain off‑road light pods. It is part of a family of bulbs (including 881, 882, 883, etc.) that share the same PG13 physical base but vary in wattage and filament configuration. The 880 specifically is often used as a high‑intensity fog or cornering light in luxury and performance vehicles.

II. Key Characteristics & Performance

1. High Power in Compact Form: Typically rated at 55W, the 880 delivers substantial light output from a relatively small bulb envelope, making it suitable for compact yet powerful auxiliary lamp housings.

2. Precision Beam Control: When installed in its matched reflector or projector, it produces a wide, flat beam pattern ideal for fog light use—illuminating the road edges and foreground without creating upward glare. In some applications, it may serve as a static cornering light that activates with turn signals to illuminate side zones at low speeds.

3. Robust Construction: The PG13 base provides a secure, vibration‑resistant connection, and the bulb is built to withstand the thermal and environmental stresses of lower‑bumper or grille‑mount locations.

III. Identification & Compatibility

• Base: PG13. This is a two‑pin glass wedge base where the pins are integral to the glass envelope. It plugs directly into a corresponding socket with spring‑clip contacts. The “PG” denotes a glass‑base pin design.

• Visual/Size Cues: The bulb is notably smaller than most headlight bulbs, with a compact cylindrical or tapered glass envelope. It often has a frosted or coated tip to diffuse light and reduce hotspot intensity.

• Compatibility Family: Shares the PG13 base with:
  — 881 (typically 50W, often used as a high‑beam auxiliary)
  — 882 (typically 5‑10W, used for parking/side marker lights)
  — 883 (higher wattage variant)
  While the base is the same, wattage and filament placement differ—substituting the wrong type may cause poor beam focus, overheating, or circuit overload.

• Common Applications: Found in OEM fog/driving lights of many European luxury vehicles (e.g., Mercedes‑Benz, BMW, Audi, Volvo), as well as some Japanese and American models. Also widely used in aftermarket auxiliary light kits.

IV. Installation & Usage Notes

• Socket Type: Uses a simple push‑in, spring‑clip socket. Ensure the pins are fully seated and the spring clips grip the bulb base securely.

• Orientation: The bulb can be inserted in any rotation (non‑polarized), but the filament orientation relative to the reflector is fixed by the lamp housing design—simply ensure it is fully pushed in.

• Power Handling: Verify the vehicle’s fog/driving light circuit is rated for 55W. Direct replacement with a higher‑wattage PG13 variant (e.g., 883) may overload wiring.

• Environmental Sealing: Many fog light housings rely on a rubber boot behind the bulb to keep out moisture. Reinstall this boot carefully after bulb replacement to prevent condensation and corrosion.
