GMC Savana high beam and low beam headlight bulbs utilize 9005 and 9006 sizes, with H6054 bulb options available for both applications. The replacement chart covers vehicle production spanning 1996 to 2024.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The GMC Savana headlight specifications reference three bulb types across its model years: the 9005, the 9006, and the H6054. The 9005 and 9006 are single-filament halogen bulbs, while the H6054 is a 5x7-inch rectangular sealed beam unit that functions as a self-contained lamp rather than a replaceable bulb within a housing.
The 9005 operates at 12V and 65W with a P20d base, and the 9006 operates at 12V and 55W with a P22d base. Despite their similar designations and shared halogen technology, the two types use different base fittings and are not interchangeable with each other.
The H6054 is a sealed beam unit, meaning the reflector, lens, and filament are fused into a single assembly. When the filament fails, the entire unit is replaced rather than an internal bulb component.
All three bulb types listed in the specifications conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical specifications within those markets.
For the GMC Savana, model years 1996-2021 carried dual fitment options for both high beam and low beam positions, with the H6054 applying to vehicles equipped with sealed beam headlamps and the 9005 or 9006 applying to those equipped with halogen capsule headlamps.
The sealed beam and halogen capsule headlamp systems on the 1996-2021 Savana are mutually exclusive configurations. A vehicle fitted with sealed beam headlamps uses the H6054 for both high and low beam functions within the same unit, while a vehicle fitted with halogen capsule headlamps uses separate 9005 and 9006 bulbs for high and low beams respectively.
Model years 2022-2024 list only the 9005 for high beam and the 9006 for low beam, with no sealed beam variant noted for those years.
The 9005 and 9006 share the same 12V operating voltage, but their wattage ratings differ. The 9005 draws 65W and the 9006 draws 55W, a distinction relevant to the electrical load each places on the vehicle's lighting circuit.
The P20d base of the 9005 and the P22d base of the 9006 are physically distinct connector types. Substituting one bulb type for the other is not supported by the specifications, as the base configurations prevent direct cross-installation.
The H6054 sealed beam unit carries a 12V rating but no wattage figure is listed in the specifications, consistent with its nature as a complete lamp assembly rather than a discrete bulb with a single filament rating.
