Types of Headlights in Silverado
Silverado models come equipped with different types of headlights. Below are the different types of headlights:
Halogen Headlights
Halogen headlights are the most common type of headlights in Silverado models. They are low-cost, easily replaceable, and offer good visibility at night. Halogen headlights work by passing an electric current through a tungsten filament, which then heats up and produces light.
LED Headlights
LED headlights are becoming more and more common in newer Silverado models. They are long-lasting, energy-efficient, and offer better illumination than halogen headlights. LED headlights work by using diodes that emit light when an electrical current is passed through them.
