2006 Tahoe Cargo Area Lights
Small Notch On Pass. Side
This automotive maintenance tutorial was specifically written to assist owners of the second generation (2000, 2001, 2002, 2003, 2004, 2005 & 2006) GM Chevrolet Tahoe SUV in changing burnt out cargo area light bulbs in the headliner by the tailgate door.

Owners of other General Motors GMT800 series SUV or truck vehicles such as the Chevy Silverado, Suburban, Avalanche, GMC Yukon, Sierra, Hummer H2 and the Cadillac Escalade may also find these DIY instructions to be helpful.

Replacement bulbs are part number 578 which are available from various manufacturers such as Sylvania, GE, PIAA and Eiko. You can also use a compatible 578 LED unit.

I recommend the Sylvania 578 Bulb.

The only tool needed to change the bulbs is a small flathead screwdriver used to pry open the hinged lens cover.

Insert Flathead Screwdriver
Pry Open Lens Cover
To prevent from scratching the plastic surfaces, you may choose to wrap the tip of your screwdriver with a thin micro fiber cloth.

Insert the blade of the small flathead in to the notch on the passenger side of the lens cover.

Gently pry open the hinged lens cover and swing it open to the right (driver side).

Pull Out Old Bulb
Old # 578 Bulb Removed
If the old bulb was recently turned on, be careful since it might still be hot enough to burn your fingers.

Pull the old bulb straight out of the socket.


Push In New Bulb
Close Hinged Lens Cover
Push a new # 578 bulb straight in to the socket.

If you would like to have brighter cargo area lights, install some compatible replacement festoon style 578 LED bulbs.

Tip - If you install LED bulbs and they don't work at first, try removing them from the socket, rotating them 180 degrees and the pushing them back into place. Some LED bulbs are polarized and will only work when installed with the + positive and - negative electrical contacts in the correct orientation.

Swing the hinged lens cover closed.

Pop In Lens Cover
Test New Cargo Area Lights
Gently pop in the retaining tab on the passenger side of the lens cover.

Test the new cargo area light bulbs by pressing the black plastic "On/Off" buttons.

Be sure to record the bulb change in your vehicle's service records.
