Lincoln LS high beam headlight bulbs use 9005 size while low beam headlight bulbs use H11, D2R, or 9006 size depending on configuration. The replacement chart covers 2000 to 2006 model years with corresponding bulb size specifications for each production year.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9005 bulb is the sole high beam specification across all Lincoln LS model years from 2000-2006. It is an ANSI-standard single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base.
The low beam specification for the Lincoln LS changed after the 2002 model year. The 2000-2002 models use the 9006 bulb, while 2003-2006 models use either H11 or D2R depending on headlamp type.
The 9006 bulb, used in low beam positions on 2000-2002 models, is an ANSI-standard single-filament halogen bulb rated at 12V and 55W with a P22d base. Although the 9005 and 9006 share a similar wattage and voltage profile, their bases differ (P20d versus P22d), making them non-interchangeable despite their physical resemblance.
The H11 bulb, used in low beam positions on halogen-equipped 2003-2006 models, follows the ECE standard and carries a PGJ19-2 base. It operates at 12V and 55W and holds approval for use in the United States despite its European origin.
The D2R bulb is the low beam specification for HID-equipped 2003-2006 models. It is a xenon discharge bulb operating at 85V and 35W with a P32d-3 base, and it is specifically engineered for reflector-type headlamp housings.
The D2R designation indicates the bulb requires a reflector housing rather than a projector housing. Substituting a D2S bulb, which is designed for projector housings, would produce incorrect light distribution and is not a compatible replacement.
Unlike halogen bulbs, the D2R operates as a high-intensity discharge (HID) lamp and requires an external ignitor to initiate and sustain the arc. This makes the electrical and installation requirements fundamentally different from the halogen options listed in the same specifications.
The 2005 high beam entry carries a notation specifying HID headlamps, while all other model years from 2000-2006 list the 9005 without such a qualifier. This indicates the 9005 serves as the high beam bulb regardless of whether the vehicle has a halogen or HID low beam system.
