Why Are Your C8 Corvette Headlights Shaking? (And How to Fix It)

How to Fix Headlight Shake in Your 2020 Chevrolet Corvette

This guide addresses headlight issues specific to the 2020 Chevrolet Corvette. If you're experiencing vibrating, shaking, or leaky headlights, this article will help you diagnose the problem and find potential solutions based on reports from other owners.

Symptoms

Owners have reported several symptoms related to the 2020 Chevrolet Corvette headlights, including:

• Headlights that vibrate or shake noticeably while driving.
• Headlights that jiggle.
• Moisture or leaks inside the headlight housing.

Most Likely Cause

Based on owner experiences, a likely culprit for shaky headlights is related to the threaded rod securing the headlight assembly.

How to Diagnose

Inspect the headlight assembly closely. Check the threaded rod and surrounding hinged pieces for any signs of looseness or damage. Gently try to move the headlight assembly by hand to see if you can replicate the shaking or vibration. Also, examine the headlight housing for any cracks or damaged seals that could be causing leaks.

Step-by-Step Fix

Since the threaded rod is a common area of concern:

1. Access the Headlight Assembly: Consult your owner's manual for instructions on how to access the headlight assembly on your vehicle.
2. Inspect the Threaded Rod: Carefully examine the threaded rod for any signs of damage, corrosion, or stripped threads.
3. Tighten the Threaded Rod: If the threaded rod is loose, try tightening it. Be careful not to overtighten, as this could damage the surrounding hinged pieces.
4. Check Hinged Pieces: Closely inspect the hinged pieces connected to the threaded rod. If they are worn or broken, they may need to be replaced.
5. Consider Aftermarket Brackets: Some owners have found success using aftermarket 4eyec5 projector brackets to improve headlight stability. Consider this option if tightening or replacing the threaded rod doesn't resolve the issue.
6. Seal Any Leaks: If you're experiencing leaks, reseal the headlight housing with appropriate sealant.

Real Owner Costs

Costs will vary depending on the specific repair needed. Replacing a threaded rod or hinged pieces may be relatively inexpensive, while replacing the entire headlight assembly, or adding aftermarket brackets, will be more costly. Labor costs will also vary depending on whether you choose to perform the repair yourself or take your truck to a mechanic.
