D4S Bulbs
D4S bulbs are a type of HID (High-Intensity Discharge) bulb used in automotive lighting. Unlike traditional halogen bulbs, HID bulbs like the D4S use an electric arc between tungsten electrodes to produce light. They are known for their high brightness and efficiency, providing excellent illumination for nighttime driving.
We usually offer various types of D4S bulbs, HID xenon and LED. In general when you have D4S bulbs, we advise to keep using D4S HID xenon bulbs. Although LED versions can be good, usually the overall light output and light pattern is less in comparison with xenon HID.
