Automotive lighting bulbs refer to the various types of lamps used in vehicles to illuminate different areas, both internally and externally. These bulbs play a crucial role in enhancing visibility during nighttime driving, improving safety, and adding aesthetic appeal. They come in various shapes, sizes, and wattages, designed for specific applications within the automotive industry. Automotive lighting bulbs can be broadly categorized into two groups: interior and exterior bulbs. Interior bulbs illuminate the vehicle's cabin, including dome lights, map lights, reading lights, glove box lights, and cargo area lights. Exterior bulbs consist of headlights, fog lights, tail lights, brake lights, turn signals, daytime running lights (DRLs), and parking lights. Each type of bulb serves a unique purpose, ensuring optimal visibility for drivers and other road users. Materials used in the construction of automotive lighting bulbs include halogen, xenon, LED, and laser technology. These materials offer distinct advantages, such as increased lifespan, energy efficiency, and brightness. Automotive lighting bulbs must comply with legal regulations and automotive standards to ensure road safety and performance consistency.
