Chevrolet Tahoe high beam headlight bulbs use 9005 or H6054 sizes, while low beam headlight bulbs use H11, D3S, or 9006 sizes depending on generation. The replacement chart covers 1995 through 2021 model years with corresponding bulb size specifications for each production period.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
ECE standard (Europe & worldwide). Mercury-free HID (xenon) discharge bulb with PK32d-5 base and integral ignitor, for projector-type housings. 42V, 35W.
The 9005 bulb is the most consistently specified high beam bulb across the Chevrolet Tahoe lineup, appearing in model years 1995-2021 wherever halogen capsule or standard halogen headlamps are fitted. It is an ANSI-standard single-filament halogen unit rated at 12V and 65W, using a P20d base.
The H6054 is a 5x7-inch rectangular sealed beam unit rated at 12V. Unlike replaceable capsule bulbs, the entire H6054 assembly is the light source itself, meaning the whole unit is exchanged rather than an internal bulb. It was specified for Chevrolet Tahoe models from 1995-1999 equipped with sealed beam headlamps.
The 9006 bulb served as the low beam halogen capsule bulb from 1995-2006, with the exception of 1995-1999 sealed beam configurations. It is an ANSI-standard single-filament halogen bulb rated at 12V and 55W, using a P22d base, making it a distinct fitment from the 9005 despite their similar appearance.
The H11 replaced the 9006 as the low beam halogen capsule bulb starting with the 2007 model year and continued through 2021. It operates under the ECE standard, carries a PGJ19-2 base, and is rated at 12V and 55W. Its base type differs from both the 9005 and 9006, and the three bulbs are not interchangeable despite sharing a 12V operating voltage.
The D3S is an HID xenon discharge bulb specified for Tahoe low beam applications from 2015-2020 on vehicles equipped with HID headlamps. It operates at 42V and 35W through a PK32d-5 base with an integral ignitor, and it is designed exclusively for projector-type housings. Its high-voltage ignition requirement makes it incompatible with standard halogen wiring.
The 1995-1999 Chevrolet Tahoe presents a dual-fitment situation for both high and low beam positions, where the correct bulb depends entirely on whether the vehicle was built with sealed beam or halogen capsule headlamps. H6054 units apply to sealed beam configurations, while 9005 and 9006 capsules apply to halogen configurations, and the two systems are not interchangeable.
From 2015-2020, the low beam position on the Tahoe accommodates either an H11 halogen bulb or a D3S HID bulb depending on the headlamp system installed. These two bulb types use entirely different bases, voltages, and housing designs, so fitment is determined by the specific headlamp assembly on the vehicle rather than the model year alone.
The 9005 and 9006 bulbs share the same ANSI classification family and 12V rating but use different base types, P20d and P22d respectively, which physically prevents cross-installation. This distinction is relevant across multiple Tahoe model years where both bulbs are present in the same headlamp assembly.
