Description: HID stands for High Intensity Discharge. HID lamps are super bright car headlight bulbs. In HID lamps, the filament is replaced with xenon gas. When the gas is exposed to high voltage, it ignites and produces a beam of light that is 3 times brighter than ordinary halogen lamps. Advantages of HID lamps: 1. High brightness and low consumption. 2. They are closer to natural light in terms of color and illuminate more efficiently. 3. They provide better visibility. HID xenon lamps with 35% less energy consumption, up to 3500 hours of lifespan. When the gas ignites, it produces a beam of light that is 3 times brighter than ordinary halogen lamps. Metal base, more durable, better heat dissipation, high temperature resistance. Plug and Play. Designed to fit your case without any wiring or other modifications required.
