HID headlights, or High-Intensity Discharge headlights, are a type of automotive lighting that uses an electric arc to produce light. Unlike traditional halogen bulbs, which rely on a filament, HID lights generate a bright, white light that can improve visibility on the road. They are often found in luxury vehicles and are known for their efficiency and longevity. These headlights typically emit a color temperature ranging from 4,000K to 6,500K, which can appear bluish compared to standard bulbs. HID headlights also consume less energy, making them a popular choice for those looking to enhance their vehicle's lighting while being more environmentally friendly.
