RLB-HILON Headlight Bracket Set for Chevy Silverado & Avalanche 2003-2007 — Pair, OEM Fit for 15798922/15798921

RLB-HILON headlight bracket is a direct-fit replacement pair (left and right) designed to mount original headlamps on Chevy Silverado and Avalanche models from 2003 through 2007.

This pair of brackets restores OEM-style alignment and secure attachment for factory headlamp assemblies. Manufactured to replace OE numbers 15798922 and 15798921, the components are supplied as a driver-side and passenger-side set so you can replace both mounts at once for even fit and consistent beam aim. They’re intended as straightforward bolt-on pieces that match the factory mounting points on compatible GM pickup and SUV variants.

How easy is installation and what tools will I need?

Installation is meant to be simple for anyone comfortable removing a headlamp assembly. The brackets align with factory mounting holes so reinstalling the headlamp uses the same fasteners and locations. Expect a basic, mechanical job without special wiring or fabrication.

• Common hand tools: ratchet, sockets, screwdrivers
• Reuse existing headlamp bolts and clips where applicable
• No trimming, drilling, or electrical work required
• Swap both sides for correct beam alignment

What are the package contents and part specifics?

Each order contains one matched pair of headlight mounting brackets: a left (driver) and right (passenger) unit. They are manufactured to meet the shape and mounting pattern of the original equipment brackets for reliable fit and to maintain proper headlight aim.

• Package includes 1 pair: driver-side and passenger-side brackets
• Formed to match OEM mounting points and contours
• Sold as replacement for OE 15798922 / 15798921
• Supplies both sides to prevent mismatched wear or alignment

Will these brackets affect headlight alignment or performance?

When installed correctly, the brackets restore the factory mounting geometry so the headlamp beam pattern returns to expected alignment. Using both new brackets at once helps ensure symmetric aiming and avoids tilt or offset caused by worn or damaged mounts.

• Restores factory mounting geometry for accurate beam aim
• Helps eliminate vibration or looseness from broken mounts
• Recommended to replace both sides for consistent alignment
• Compatible with original headlamp assemblies—no aftermarket reshaping

Who is this for: Owners of early-2000s Chevrolet Silverado or Avalanche vehicles seeking a cost-effective, OEM-style replacement for damaged or worn headlamp mounting brackets. It’s best for DIY mechanics, repair shops, or anyone restoring proper headlight alignment without replacing the entire headlamp assembly.
