Headlight conversion refers to the process of replacing or upgrading a vehicle’s original headlight system with a different type of lighting technology or assembly. This can include changing from halogen to HID (High Intensity Discharge), LED, or projector-style headlights, as well as retrofitting newer headlight housings or lens styles onto an older vehicle. The goal is often to improve visibility, modernize the vehicle’s appearance, or comply with specific lighting preferences or standards.
