2008-2017 Sequoia Headlight Bulb Change How-To

Got an easy one here – replaced my Sequoia low-beam bulbs today. The lights had been looking fairly dim before this, and as it turned out, the passenger’s side headlight was out. The foglights that I always run had been masking the issue to a degree. The low beam bulbs are H11s, and are accessible without removing anything on the car. It can be a little tight to access but I had no issues here.

With anything electrical, disconnecting the battery is recommended. This is one of the easiest jobs to do on this car, or any car, but sometimes pictures are still helpful. With halogen style bulbs, the bulbs have a twist-lock mechanism that holds the bulb in place. Twist counter-clockwise to release the bulb, and pull it back.

Passenger bulb out

The low beam bulbs are the two farthest out bulbs accessible in the engine bay – both are relatively easy to access. The driver’s side is located to the outside of the battery, and the passenger’s side is located to the outside of the windshield wiper fluid reservoir.

As mentioned, twist the plug counter-clockwise, and pull back to remove the bulb. Note the orientation of the bulbs, as they will need to be reinstalled in the same orientation. Once the bulb is out, remove the bulb from the clip and install the new bulb. Do not touch the new bulb with bare hands, as the oils from your fingers can cause the bulb to overheat and die early.

Neither bulb was in great shape, it seems the seal had deteriorated on both, with it not even being attached to the passenger’s side bulb any longer – I had to remove the seal from the headlight housing. This could have caused premature failure on the bulbs.

It will take some finesse to reinstall the bulbs, but if you noted how they were installed, this should be pretty straightforward. Install it pre-turned and it should go straight in, and turn clockwise to lock in place.

The lights are definitely brighter, but the car really needs a wash and probably a headlight restoration job to remove some of the fade.
