Oldsmobile Bravada Headlight Bulb Size

Additional Notes

• The Oldsmobile Bravada uses two distinct headlight systems across its production years. The 1991-1994 model years use the H6054 sealed beam unit for both high and low beam functions, while the 1996-2004 model years use separate 9005 and 9006 halogen bulbs for high and low beams respectively.
• The H6054 is a 5x7-inch rectangular sealed beam unit rated at 12V. Unlike a conventional replaceable bulb, the lens, reflector, and filament are fused into a single assembly, meaning the entire unit is replaced when the light fails.
• The 9005 bulb, used for high beam on the 1996-2004 Bravada, is a single-filament halogen type rated at 12V and 65W, fitted with a P20d base. It conforms to ANSI standards applicable in both the United States and Canada.
• The 9006 bulb, used for low beam on the 1996-2004 Bravada, is also a single-filament halogen type rated at 12V but draws 55W, which is 10 watts less than the 9005. It uses a P22d base, which is physically different from the P20d base of the 9005.
• The differing base types between the 9005 (P20d) and 9006 (P22d) mean the two bulbs are not interchangeable, despite their otherwise similar construction and shared 12V rating.
• The specifications contain no entry for the 1995 model year across either the high beam or low beam positions, indicating that year falls outside the documented fitment data for the Bravada.
• The H6054 sealed beam format handles both high and low beam output within a single unit, whereas the 1996-2004 system separates those functions into two distinct bulbs, each with its own socket and wattage rating.
• All bulb types listed across both headlight positions conform to ANSI standards recognized in the United States and Canada, classifying them as standardized rather than proprietary fitments.
