Xenon D1S Bulb
The Xenon D1S variant is often used for Xenon bulbs. The "D" stands for "discharge" and, of course, indicates that this bulb is a gas discharge lamp. The number "1" indicates the type designation of the plug connectionas well as the respective design version, and "S" stands for the respective glass bulb type. Type-S glass bulbs are meant for headlights with a lens system. In the case of Xenon D1S bulbs, the ignition unit has been integrated and requires an operating voltage of approximately 85 volts. This is one of the first Xenon bulbs that do not feature an outer glass bulb protecting the discharge tube. Replacing this bulb with a D3 bulb is impossible because the operating voltage would no longer be correct.
