What headlight bulb does a 2017 Chevy Tahoe use?

The 2017 Chevy Tahoe uses H11 bulbs for the low beams and 9005 bulbs for the high beams; fog lights typically use H11 as well.

For Tahoe owners, knowing the exact bulb sizes helps with maintenance, replacements, and any potential upgrades. The configuration is shared with GM trucks of the same generation, though there can be trim-level variations or aftermarket options.

Bulb types by function

The following quick reference lists the bulb sizes used for each headlight function in most 2017 Tahoe models.

• Low beam: H11


• High beam: 9005 (HB3)


• Fog lights: H11

Sizes can vary by trim or production date; always verify by checking the owner’s manual or the label on the headlight housing if in doubt.

Replacing the bulbs

Owners who replace bulbs themselves should follow these steps to avoid damage or improper seating.

1. Park on a level surface, turn off the engine, and open the hood.


2. Access the back of the headlight housing from the engine bay; remove the dust cap if present.


3. Disconnect the wiring harness from the bulb.


4. Turn the bulb counterclockwise to release it from the socket, then carefully pull it out.


5. Handle the new bulb with clean gloves or a cloth; insert it into the socket and rotate clockwise to secure.


6. Reconnect the wiring harness and replace the dust cap; test the lights before closing the hood.

Be careful not to touch the glass with bare skin, as oils can shorten bulb life; if you do touch the glass, clean it with rubbing alcohol and a lint-free cloth before installation.

Considerations and variants

Trim-level differences and upgrades

Some Tahoe trims offer different headlight configurations, such as LED or HID retrofit options. If your vehicle has aftermarket lights or a factory upgrade, the bulbs may differ. Check your owner’s manual or consult a dealer to confirm the exact bulb type for your VIN.
