Car Accessories LED Headlight Extended Seal Rear Cover 90mm Black Silicone Dust Protection

Upgrading your headlights to LED bulbs often leaves a gap around the bulb base where dust and moisture can enter the housing. This extended seal rear cover is designed to close that gap, providing a protective barrier that keeps your headlight components clean and dry. Made from flexible black silicone, the cover fits over the back of the bulb socket and seals against the headlight housing. At 90mm in diameter, it is sized to accommodate many common aftermarket LED bulbs. Whether you are retrofitting a General Motors vehicle or another compatible model, this simple accessory adds an extra layer of protection to your lighting system.

Features and Construction

This dust cover is built around a straightforward functional design: a silicone cap that fits over the bulb base and extends outward to create a sealed enclosure. Its material choice and size work together to deliver reliable protection without complicating installation.

Material and Build

The cover is moulded from black silicone, a material chosen for its flexibility and resistance to temperature changes. Silicone conforms easily to irregular shapes, allowing the cover to create a snug fit around the bulb base and headlight housing opening. It does not crack or harden quickly under normal under-bonnet conditions, making it suitable for long-term use.

Size and Practical Fit

With a diameter of 90mm, the cover is designed to fit a range of aftermarket LED bulb assemblies. It is not a one-size-fits-all item, but its dimensions match many standard bulb bases used in retrofit kits. The black colour helps it blend into the headlight assembly visually.

Uses and Placement

This dust cover is intended for use on the rear side of a headlight housing, where the bulb base protrudes after installation. It is particularly useful for vehicles originally designed for halogen bulbs that have been converted to LED.

Vehicle Conversion Use

When replacing halogen bulbs with aftermarket LED units, the bulb base is often longer than the original. This leaves the rear of the housing open to contaminants. This cover seals that opening, maintaining the integrity of the headlight assembly.

Everyday Protection

Even on factory LED-equipped models, a sealed cover helps keep dust, road grime, and moisture from entering the housing. This reduces the need for frequent cleaning and helps maintain consistent light output over time.

Benefits and Buying Value

The primary value of this cover lies in its straightforward protection function. It is a low-cost accessory that can extend the cleanliness and reliability of your headlight system.

Simple Installation

Because the silicone material is flexible, the cover can be pushed into place by hand. No tools or adhesives are required, making it easy to fit or remove when servicing the bulb.

Why Choose This Product

If you have already invested in aftermarket LED headlight bulbs, adding a proper dust cover helps protect that investment. This cover is a practical, no-fuss way to seal the housing without modifying the vehicle.
