Saturn Outlook high beam headlight bulbs utilize D1S and 9005 sizes, while low beam headlight bulbs use D1S and H11 sizes. The replacement chart covers 2007 through 2010 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 Saturn Outlook (2007-2010) uses two distinct headlamp system types across all four model years: HID (High-Intensity Discharge) and halogen capsule. The correct bulb type depends entirely on which system the vehicle was built with.
The D1S is an HID xenon discharge bulb operating at 85V and 35W. It follows the ECE standard used in Europe and worldwide, features a PK32d-2 base with an integral ignitor, and is designed specifically for projector-type housings. It serves as both the high beam and low beam bulb in Outlook vehicles equipped with HID headlamps across all model years in the specifications.
Because the D1S operates at 85 volts and includes a built-in ignitor, it is electrically and physically incompatible with the 12-volt halogen system. The two headlamp configurations on the Saturn Outlook are not interchangeable.
Outlook vehicles equipped with halogen capsule headlamps use two different bulb types depending on the function. The high beam position takes a 9005 bulb, while the low beam position takes an H11 bulb.
The 9005 follows the ANSI standard used in the US and Canada. It is a single-filament halogen bulb with a P20d base, rated at 12V and 65W. Its wattage is notably higher than the H11, reflecting its role as a dedicated high beam source.
The H11 follows the ECE standard and carries additional US approval. It is a single-filament halogen bulb with a PGJ19-2 base, rated at 12V and 55W. The PGJ19-2 base differs from the P20d base of the 9005, making the two halogen bulbs physically non-interchangeable despite sharing the same operating voltage.
The single-filament design of both the 9005 and H11 means each bulb handles only one lighting function. This contrasts with dual-filament bulbs, which combine high and low beam functions in a single unit. The Outlook halogen system therefore requires separate bulbs for each beam position.
The D1S bulb's integral ignitor distinguishes it from other HID types such as the D2S, which requires an external ignitor. This integration affects replacement compatibility, as D1S bulbs are not interchangeable with other D-series HID types even when wattage ratings are similar.
