Headlight

Headlights are vehicle-mounted illumination devices providing forward visibility during periods of darkness or reduced visibility. Typically located at the front of the vehicle, they utilize various light sources—incandescent, halogen, HID, or LED—to project a concentrated beam onto the roadway. Modern headlights commonly integrate reflectors and lenses optimized for beam pattern and intensity, adhering to specific photometric standards. Many assemblies now incorporate dedicated daytime running lights (DRLs) and turn signal indicators. Construction materials include durable polymers for housings and impact-resistant polycarbonate or glass for lenses, designed to withstand road debris and environmental factors.
