D series LED headlights refer to the original car headlights which are HID headlight systems. With the development of technology, many OEM manufacturers have developed LED D series headlights adapted to the original vehicle system. D series LED headlights can directly replace the original car HID headlight bulbs. Compared with original car bulbs, Led bulbs are brighter, have more accurate color temperature, and have a longer service life, which can fully meet the needs of drivers.
