This automotive maintenance tutorial was specifically written to assist owners of the third generation (2007, 2008, 2009, 2010, 2011, 2012, 2013 & 2014) Chevrolet Tahoe in changing a burnt out low beam, high beam, front turn signal, DRL (daytime running light) or side marker light bulb in the headlight assemblies.

Owners of related General Motors full size SUV or truck vehicles with similar headlight housings such as the Suburban, Avalanche, GMC Yukon, Yukon XL, Yukon Denali, Sierra, Cadillac Escalade and Hummer H2 may also find these DIY instructions to be helpful.

Replacement bulbs with their part numbers are as follows: Low Beam # H11, High Beam # 9005, Turn Signal # 3157NA or 3157AK, DRL (Daytime Running Lamp) # 3157 or 3157K and Front Sidemarker # 194 (or 168, W5W and 2825).


To replace the Low Beam headlight bulb on the Driver Side of the vehicle, you'll need the following tools: a 10mm socket with a 1/4" drive ratcheting wrench, a pair of needle nose pliers and a flathead screwdriver.

To replace the Low Beam headlight bulb on the Passenger Side of the SUV, you'll need the following tools: a Torx T-25 star bit screwdriver, a 10mm socket with a 1/4" drive ratcheting wrench, a pair of needle nose pliers and a flathead screwdriver.

If you need to replace any of the other bulbs, it would be best to partially detach the front bumper cover in order to remove the headlight housing. (You may be able to reach the high beam bulbs with out entirely removing the headlight.)

To separate the headlight assembly from the vehicle, you'll need the following tools: a 10mm socket with a 1/4" drive ratcheting wrench, a 7mm socket, a flathead screwdriver and a pair of needle nose pliers.

To access the Low Beam headlight bulb on the Driver Side, first remove the single 10mm bolt holding the window washer fluid bottle in place to the front of the engine bay frame.

Set the bolt aside in a safe place.

Then remove the black plastic friction fastener, which holds two rubber tubes in place, by using a pair of needle nose pliers or pry it out with a flathead screwdriver.

Close the rubber flap to cover the low beam bulb and push in the pop rivet friction fastener with the loop that holds the two thin rubber hoses in place.

Re-insert the 10mm bolt to secure the windshield washer fluid bottle in place and tighten it in the clockwise direction.

If you need to replace the High Beam bulb on the Driver Side, scroll down to my pictures of the procedure done on the passenger side headlight. It involves removing the two 10mm upper headlight bolts in order to slightly pull out the top of the housing and make enough room to reach the high beam bulb.


At this point in the tutorial, we are going to move over to the Passenger Side Headlight.

First, I'll show you how to replace either the Low Beam or High Beam bulb by removing the engine air filter box.

Then we'll entirely remove the headlight assembly in order to reach the Turn Signal, DRL (daytime running light) and Front Side Marker light bulbs.

Firmly pull out the bottom half of the air box from the engine bay.

The lower half of the air box is held in place by a few plastic pegs on the underside of the box that insert in to rubber grommets and act as friction fasteners.

Pull back the rubber cover and you'll see the green/black base of the old low beam bulb.

Since there isn't enough room to rotate the low beam bulb and remove it, we'll need to remove two bolts on the top of the headlight housing.
