Lincoln Aviator high beam headlight bulbs use 9005 size, while low beam headlight bulbs use H11 or D2R size. The replacement chart covers 2003 to 2005 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Lincoln Aviator uses three distinct bulb types across its headlight system for the 2003-2005 model years: the 9005 for high beams, and either the H11 or D2R for low beams, depending on the headlamp configuration installed at the factory.
The 9005 is an ANSI-standard single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base. It serves as the high beam bulb across all three model years covered in the specifications.
The H11 is an ECE-standard single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base. It is the low beam bulb in Aviator vehicles equipped with halogen capsule headlamps.
The D2R is an HID xenon discharge bulb rated at 85V and 35W, using a P32d-3 base. It is designed specifically for reflector-type housings and requires an external ignitor to operate, making it electrically and mechanically incompatible with standard halogen sockets.
The Lincoln Aviator (2003-2005) offered two distinct low beam headlamp systems, halogen and HID, meaning the correct replacement bulb depends on which system the individual vehicle was built with.
The H11 and D2R are not interchangeable. Their base types, operating voltages, and required circuitry differ substantially, and substituting one for the other is not supported by the specifications.
Although the 9005 and H11 are both 12V halogen bulbs, their base types differ. The 9005 uses a P20d base while the H11 uses a PGJ19-2 base, which prevents cross-fitment between the high beam and low beam positions.
The D2R designation indicates the bulb is rated for reflector-style optical housings, as opposed to the D2S variant used in projector housings. Using a D2S in a reflector housing, or vice versa, produces incorrect light distribution on the road.
