Vehicle lighting components provide illumination for visibility and signaling, functioning at the front, rear, and interior of the vehicle. These systems utilize various technologies including halogen, LED, and discharge lamps to generate light, often incorporating reflective housings and lenses for beam control. Modern lighting increasingly features electronically controlled intensity and aiming, integrated with vehicle systems for automatic operation. Signal assemblies employ standardized bulb/LED configurations and flash patterns to communicate intent to other drivers. Housings are constructed from impact-resistant polymers or glass, and wiring harnesses utilize sealed connectors for environmental protection.
