ALI Premium 4300K D1S HID/Xenon Headlight Bulbs (Pack of 2)

Comprehensive Details

D1S - SET of 2 - OSRAM 4300K OEM HID Xenon Light 66144, 35W DOT, Made in Germany | Pack of 2

Our D1S LED lights (model 66144) come in standard packaging without the TRUST code. If you require the 7-digit TRUST code, please consider our 66140 model at a higher price.

These lights are compatible with any vehicle that uses D1S type bulbs. They are OEM 4300K, with 3200LM, 85V, and 35W, making them a direct factory replacement. The 4300K rating represents a standard white color. For cooler tones, you may need 6000K or higher.

All HID lights will discolor and dim over time, becoming whiter or bluer. When comparing a new bulb to an old one, the new bulb may appear warmer in color initially. Replacing the bulbs in pairs is recommended for optimal performance.

These lights offer extremely long life with precise light distribution and consistent performance. They are DOT approved and 100% legal for on-road and off-road use. If you experience light failure, try working the side bulb on the non-working side to confirm if it's the bulb that needs replacement.

Before ordering, ensure compatibility. D1S bulbs cannot be used for D3S applications. These are not halogen lights, and HID bulbs do not fit in halogen lamp sockets. WARNING: This is a D1S Type bulb, not a D3S.

All our bulbs have been tested through Osram’s multiple layers of quality control, and we have not experienced even one defective case.
