How to Change Headlight on 2010 Toyota Tundra | Full Assembly Removal

Changing the headlight on a 2010 Toyota Tundra requires removing the entire assembly rather than just swapping the bulb.

Most pickup owners expect a quick bulb swap, but the second-generation Tundra (2007–2013) takes a different approach. The whole headlight housing must come out to access either the low-beam or high-beam bulb. Once you know where the clips, fasteners, and release tabs are, it’s a straightforward job that saves a shop fee.

Why the 2010 Tundra Needs Assembly Removal

Toyota designed the Tundra’s front lighting with the bulb sockets mounted to the back of a sealed housing. You cannot reach the bulb retainer or twist-lock base from behind the fender well or through a service hatch — both common access points on other trucks. The only path to the bulbs is to pull the entire assembly forward, unplug the connectors, and work on it on your workbench or tailgate. This design applies to all trims of the North American 2010 Tundra.

Knowing this upfront prevents the frustration of spending 10 minutes trying to twist a bulb out through a gap that doesn’t exist.

Step-by-Step: Removing the Headlight Assembly

The job breaks into five actions. You’ll need a trim tool or flathead screwdriver, a 10mm socket or wrench, and a clean cloth to handle the new bulb glass.

1. Remove the two plastic push clips that secure the upper radiator support trim. Pop the center pin out with a trim tool or small screwdriver, then pull the whole clip free. Set them aside in a safe spot — they’re small and easy to lose.
2. Pry off the trim bezel that sits between the grille and the headlight housing. It snaps into place with plastic retaining clips. Work from the outer edge inward; the bezel bends slightly without breaking if you go slowly. Once free, set it aside.
3. Unscrew the three 10mm fasteners securing the assembly. You’ll find one bolt near the top center of the housing and two screws along the top edge. A 10mm socket on a short ratchet makes quick work of them; a 10mm combination wrench works if space is tight.
4. Lift the assembly upward about half an inch to disengage the two bottom alignment tabs from the sheet metal slots. Pull the housing straight toward you once the tabs are clear. It should come free without forcing it.
5. Unplug the four bulb connectors — low beam, high beam, turn signal, and side marker. Each connector has a small locking tab; press it and pull. Labeling them with masking tape before unplugging saves head-scratching during reinstallation.

When it’s time to go back together, reverse the steps. Push the assembly down firmly to seat the bottom tabs, torque the 10mm fasteners snug (about 7 ft-lbs), snap the bezel on, and reinstall the push clips with the pins set to the locked position.

If your factory housings are yellowed, cracked, or leaking moisture, this is the right moment to swap them entirely. Browse replacement assemblies and upgrade options in our roundup of the best 2010 Tundra headlights to see what fits your truck and budget.

Bulb Types and What You’ll Need

The 2010 Tundra uses two different bulb sizes for the main beams. Grabbing the wrong one is the most common mistake, so check the table before you buy.

Choose bulbs from a reputable brand — the step-by-step video at CarCareKiosk confirms the standard sizes above. High beams in 9005 are available in long-life halogens or bright LEDs. The turn signal and side marker bulbs rarely fail, but swapping them while the assembly is off adds only a few seconds.
