Dorman Rectangular Headlamp Retaining Ring with 4 Screws — Steel Universal Fit, Restores Alignment

The Dorman 42407 is a steel rectangular headlamp retaining ring with four mounting screws that replaces a failed original to secure and align rectangular headlights.

When a headlamp retaining ring is bent, cracked, or corroded after a collision or years of exposure, the headlight can wobble, misalign, or allow moisture inside the housing. The Dorman 42407 is made to fit the same mounting points and hold a variety of rectangular headlights in place while resisting vibration and the elements. It’s engineered as a dependable, service‑grade replacement for vehicles that originally used a similar ring design.

How does this retaining ring restore headlight fit and alignment?

The Dorman 42407 re-establishes the correct geometry between the lamp bezel and the vehicle’s mounting points, preventing light movement and improper aim. Replacing a damaged ring removes play that can cause the beam to bounce under load or after hitting a pothole.

• Exact-shaped rectangular ring to match original mounting geometry
• Four included screws for secure attachment to the headlamp housing
• Steel construction maintains bracket integrity under vibration
• Restores proper beam aim and reduces lamp movement

What materials and durability can I expect from this replacement?

How difficult is installation and what tools are needed?
