Premium OSRAM XENARC OEM D1S HID/Xenon Headlight Bulbs

This listing is for a set of 2 genuine OSRAM D1S type HID/Xenon headlight bulbs, model# 66144. These 4300K OEM HID Xenon lights have a 35W output and are DOT approved for on and off-road use. The bulbs feature an 11-digit security label (not a 7-digit TRUST code).

The 66144 model comes with an 11-digit serial number sticker only. If you require a 7-digit TRUST code, you should view the 66140 model, which is priced higher. Please note that only the upgraded OSRAM HID bulbs, such as XNL, CBI, CBB, etc., that have a 7-digit TRUST code will provide a matching batch number on the bulb label and the metal base cap.

As long as your vehicle is compatible with the D1S type bulb, these 4300K, 3200LM, 85V 35W bulbs are direct factory replacements. The 4300K color is considered a 'standard white', and if you desire a cooler color, you would need to find 6000K or higher.

It is important to note that all HID lights will discolor and become whiter/bluer over time, and the new bulb may appear warmer in color compared to the old one, which is normal. Replacing the bulbs in pairs is recommended for optimal performance.

These OSRAM HID/Xenon bulbs offer an extremely long life with precise light distribution and consistent performance. They are DOT approved and 100% legal for on and off-road use. When experiencing a light failure, it is advised to try the working side bulb on the non-working side to ensure the issue is with the bulb itself.

Before ordering, please double-check the compatibility of your vehicle. This is a D1S type bulb and cannot be used for D3S applications. These are not halogen lights, and HID bulbs cannot be used with halogen lamps (WARNING: This is a D1S type bulb, not D3S).

Do not use these bulbs for troubleshooting purposes, but only order them when you need to replace a bulb. All OSRAM bulbs have undergone multiple layers of quality control, and the manufacturer has not had a single reported defective case.
