For the 2005 Chevrolet Tahoe, the supplied fitment data lists a 9005 high-beam bulb. No low-beam bulb specification is provided, so verify the original low-beam bulb before ordering. The fog lights use 880 bulbs.
Other notable exterior bulb sizes include 4157NA for the front turn signals and parking lights, 194NA for the front side markers, and 3157 for the rear turn signals and reverse lights. The brake and tail lights use 3157R. The center stop light is listed as LED.
Interior and utility lighting includes a 578 dome and trunk light, 93 engine-compartment light, and 7065 vanity light. Courtesy, map, and instrument lighting require comparison with the original bulb because multiple options are listed. License-plate and glove-box applications may use either 194 or 7441, so compare the installed bulb before replacement.
