All automotive bulbs are liable to fail and/or deteriorate over time, with their lifespan depending on several factors that include voltage, vibration, and usage. As a safety-critical part, it is important to regularly check bulbs and replace them in pairs to allow a clear, brighter view of the roads and ensure driver safety.
