GMC Safari Headlight Bulb Size

GMC Safari headlight bulbs utilize H6054 and 9005 sizes for high beam applications, while low beam configurations require H6054 and 9006 bulb sizes. The replacement chart covers 1985 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.

Additional Notes

The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V. Unlike replaceable capsule bulbs, the entire H6054 assembly is replaced as a single unit when it fails. It serves both high beam and low beam functions within one housing, which is why the GMC Safari lists it for both positions across all model years covered in the specifications.
The GMC Safari used the H6054 as the sole headlight bulb type from 1985-1994, covering both high and low beam positions throughout that period.
From 1995-2005, the Safari was produced with two distinct headlamp system configurations: sealed beam and halogen capsule. The sealed beam variant continued to use the H6054, while the halogen capsule variant used separate bulbs for each beam function.
The 9005 is a single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base. It is designated for the high beam position in Safari models from 1995-2005 equipped with halogen capsule headlamps.
The 9006 is a single-filament halogen bulb rated at 12V and 55W, fitted with a P22d base. It is designated for the low beam position in the same 1995-2005 halogen capsule configuration. Its lower wattage relative to the 9005 reflects the differing power demands between low and high beam operation.
The 9005 and 9006 share a similar physical profile but have different base types, P20d and P22d respectively. This difference in base design prevents cross-installation between the high and low beam sockets.
All three bulb types listed in the specifications, the H6054, 9005, and 9006, conform to ANSI standards recognized in both the United States and Canada, and all operate on a 12V electrical system.
The halogen capsule configuration introduced from 1995 onward requires two separate bulb part numbers to cover both beam functions, whereas the sealed beam configuration requires only the H6054 regardless of beam position.
