Quantity: Pack of 10 headlamp socket adapter bases — enough spares for routine replacements, kits, or multiple vehicles. Function: Converts and secures LED headlight bulbs into the existing headlight assembly. Acts as a dedicated adapter base to hold and align the bulb correctly. Design: Monolithic conversion adapter specially designed for LED headlight bulbs, providing a singlepiece, stable connection with consistent fit and electrical contact. Material & Durability: Made from ABS plastic that is corrosion resistant and impact resistant. Built for durability and long service life in automotive environments. Installation: Simple plugin installation — the LED headlight bulb base plugs directly into the headlight assembly without modification, reducing installation time and the need for tools or custom adapters. Compatibility: Intended for use with LED headlight bulbs and compatible headlight assemblies that accept a standard adapter base. Use these bases when replacing worn or damaged sockets or when fitting LED bulbs that require a conversion adapter. Performance: Provides a stable mechanical and electrical interface between the LED bulb and vehicle headlight assembly, helping maintain proper beam alignment and reliable operation over time. Use scenarios: Routine maintenance: worn or cracked socket bases on a vehicle to restore secure bulb seating and reduce flicker or poor alignment. LED conversions: When upgrading from halogen to LED bulbs that require a dedicated adapter base, use these monolithic adapters to ensure a proper fit without cutting or modifying the headlight assembly. Fleet or workshop spares: Keep a pack of 10 on hand for quick repairs in a fleet, taxi, or service where multiple vehicles may need headlight socket replacement. What you get: Ten ABS headlight base adapters, each built for corrosion resistance and longterm use, ready to plug into compatible headlight assemblies and support LED headlight bulbs.
