Understanding the Problem: Why Car Lights Crack
Car lights crack for various reasons, from impacts with road debris to extreme temperature changes. Understanding the cause can help you prevent future cracks. Common culprits include rocks, hail, and even accidentally bumping into something in your garage. Temperature fluctuations can also cause the plastic lens to expand and contract, leading to stress cracks over time.

Assessing the Damage: Repair or Replace?
Before you start, determine the extent of the damage. A minor crack might be repairable with a sealant, while a severely damaged light likely requires replacement. Inspect the crack carefully.
