Overview

The Osram 66144 is a D1S HID Xenon headlight bulb designed as a direct replacement for burnt-out low beam bulbs. It features a 4300K color temperature, which is equivalent to OE HID headlight bulbs and provides light closer to natural daylight. The bulb operates at 35W and produces 3200 lumens. Osram recommends replacing HID bulbs in pairs to ensure consistent light color between headlights. The bulb is made in Germany and is of OE quality.

Show original supplier description

The Osram 66144 is a D1S HID Xenon headlight bulb, engineered as a direct replacement for factory-equipped low beam HID bulbs. This bulb operates at 35 watts, produces 3200 lumens, and has a color temperature of 4300K, designed to match the natural daylight spectrum for improved visibility and reduced eye strain. It features a PK32d-2 base for a secure connection. Osram recommends replacing HID bulbs in pairs to maintain consistent light color and brightness between both headlights. This ensures a uniform appearance and optimal illumination. The "XENARC ORIGINAL" line signifies OEM quality, successfully used in millions of new vehicles from renowned manufacturers as both initial equipment and original spare parts. OSRAM provides a 4-year guarantee for these lamps. Installation of XENARC lamps is recommended to be carried out by a professional. The fitment notes specify that this bulb is for Xenon headlights with the D1S type bulb (square base). It is explicitly noted for various Porsche 911 models from 1995-1998 and Audi A4 models from 2002-2003, with specific chassis number or Xenon headlight requirements. For example, 2002 Audi A4 models require "From chassis # 8E-2-115715" or "Only for Xenon headlight with D1S type bulb (square base)". A customer review noted that despite a listing stating it did not fit a 2012 BMW 328i E92 LCI, the D1S bulb did work.
