Modern headlights are electrically operated, positioned in pairs, one headlight or two headlights on each side of the front of a vehicle. Headlights are really the eyes of a vehicle.
Headlights are typically of sealed beam construction type, which feature reflectors, filament and special lenses fused together into an airtight unit.
Headlights are crafted to have prongs that fit into a wiring socket for the purpose of easy installation and removal,
and so even a regular driver can do it by him/herself.
