Partomotive - Headlights

A headlamp is a lamp attached to the front of a vehicle to light the road ahead. While it is common for the term headlight to be used interchangeably in informal discussion, headlamp is the term for the device itself, while headlight properly refers to the beam of light produced and distributed by the device. The lens and the housing are the main components of an assembly. Bulbs and the sockets are not always part of an assembly and are sold as separate components.
