Features and Construction

Constructed from durable plastic material, this lamp holder combines practical functionality with straightforward installation requirements. The 30.7mm width, 10mm depth, and 26mm height dimensions provide exact fitting specifications that match factory headlight component spacing. This precision engineering ensures stable bulb mounting without unnecessary movement or vibration.
Material and Build
The black plastic construction offers several practical advantages for automotive applications. Plastic provides electrical insulation between bulb components and vehicle wiring systems, reducing potential short-circuit risks. The material's heat resistance properties help maintain structural integrity under normal headlight operating temperatures. Unlike metal alternatives, plastic won't corrode from moisture exposure or create galvanic corrosion issues when contacting dissimilar metals.
Size and Practical Fit
With dimensions of 30.7mm in width, 10mm in depth, and 26mm in height, this holder delivers precise dimensional accuracy crucial for proper bulb alignment. The 30.7mm width ensures adequate spacing between adjacent components within the headlight housing, while the 10mm depth provides sufficient mounting surface area. The 26mm height accommodates standard H1 bulb base dimensions while allowing clearance for wiring connections. These measurements work together to create a secure fit without requiring modifications to factory headlight assemblies.
Uses and Placement
This adapter bracket serves a specific technical function within vehicle lighting systems, enabling bulb technology conversion while maintaining proper mounting geometry. Its primary application involves upgrading from traditional H1 halogen bulbs to modern LED alternatives in compatible Ford vehicles.
Event or Professional Use
For automotive workshops and professional installers, this holder provides a reliable solution for customers seeking LED lighting upgrades on compatible Ford models. The precise 30.7x10x26mm dimensions ensure consistent fitting across multiple vehicles, reducing installation time and potential fitment issues. Professional users benefit from the straightforward single-piece design that requires no additional components for basic H1 to LED conversions.
Everyday Home Use
For vehicle owners undertaking their own lighting upgrades, this black plastic holder offers a manageable installation process with clear compatibility parameters. The single-piece design simplifies the upgrade procedure while the plastic construction reduces weight and handling complexity. DIY enthusiasts appreciate the exact dimensional specifications that eliminate guesswork during installation, particularly for those working with limited automotive modification experience.
Benefits and Buying Value
This lamp holder delivers practical value through its targeted compatibility and precise engineering, addressing specific conversion needs without unnecessary complexity.
Reuse and Low Maintenance
The plastic construction requires minimal maintenance beyond occasional inspection for secure mounting. Unlike components with moving parts or electrical contacts requiring regular cleaning, this holder maintains functionality through its simple structural design. The material's resistance to typical under-bonnet environmental factors supports long-term reliability without demanding specialist care routines.
