Headlights

A headlight is also referred to as a headlamp. It is attached to the front of the vehicle to light up the road ahead. The headlight performance has gradually developed throughout generations. Each moving object powered by the engine should have a headlight, like the car itself, the train, aero plane, and motorbike.
To add on, the headlights design and style is always known to be round in shape for a long time, since the native shape of parabolic reflector is round. The round shape helps to project light and focus the beam.
