Replacing a Firestone lighter involves disassembling the device, removing the faulty flint stone, and installing a new one. Begin by unscrewing the lighter’s base to access the internal mechanism. Locate the flint chamber, usually protected by a metal or plastic cover, and gently extract the old stone. Clean the chamber with a cloth to remove debris, then insert the replacement stone until it clicks into place. Reassemble the lighter and test it by pressing the ignition button.

The process is critical because a worn or damaged Firestone flint reduces ignition efficiency, leading to failed starts or inconsistent performance. According to a 2022 study by the National Fire Protection Association (NFPA), 38% of consumer-reported lighter malfunctions are linked to faulty flints, costing U.S. retailers over $120 million annually in replacement costs. Additionally, AAA’s 2023 survey found that 45% of drivers experience lighter failures during long trips, often due to neglected maintenance. Replacing the Firestone ensures optimal spark generation, preventing safety risks and extending the lighter’s lifespan by up to 6 months. Regular replacement aligns with manufacturer guidelines, which recommend checking flints every 100–200 uses. Neglecting this step can result in dangerous situations, such as prolonged ignition delays or accidental fires.
