Halogen headlights are a type of automotive lighting that uses a tungsten filament enclosed in a glass bulb filled with halogen gas. This design allows the filament to burn hotter and brighter than traditional incandescent bulbs, resulting in improved visibility on the road. Halogen headlights are commonly found in many vehicles due to their affordability and effectiveness. These headlights typically have a longer lifespan than standard bulbs, lasting about 500 to 1,000 hours. However, they can produce more heat, which may lead to a risk of damage if touched during installation. Overall, halogen headlights remain a popular choice for drivers seeking reliable illumination.
