The headlight assembly of a 07-12 Nissan Altima contains the following bulbs with their corresponding Sylvania part numbers: Low Beam # H11, High Beam # H9, Turn Signal / Parking Light # 3457A, and Side Marker # 2825.

To access the low beam, turn signal and side marker bulbs, you'll need both a flathead and a Phillips head screwdriver.

To replace the passenger high beam bulb you'll need a 10mm socket for removing the coolant overflow bottle.

(Accessing the driver side high beam may require removing the 12V battery.)

In this guide, I've turned the steering wheel all the way to the left in order to gain some extra clearance for replacing the headlight bulbs on the passenger side of the car.

If you just need to replace the passenger side high beam bulb, remove the coolant overflow bottle by unscrewing the single 10mm bolt that holds it into place.

To access the high beam bulb on the driver side, remove the battery.

One is located deep in the wheel well by the suspension spring, another is in front of the tire, and the third is at the top outer edge.

Remove them by gently prying the fasteners out with a small flathead screwdriver inserted into their indentations.

Next locate the single Phillips head screw that attaches the black plastic wheel well cover to the bottom lip of the painted bumper cover and remove it with a Phillips head screwdriver.

The small side marker bulb socket and slightly larger turn signal bulb socket are both light grey in color and located next to each other at the top of the headlight assembly.

To remove it, first depress the tab on the power connector and wiggle it off the bulb's base.

Then turn the base 1/4 turn counter clockwise and carefully pull it out of the socket in the headlight assembly.

If you do touch the bulb, clean it with a tissue moistened with rubbing alcohol to remove any oil, dirt, or fingerprints left on the glass.

Insert the new H11 low beam bulb into the socket in the headlight assembly and rotate it 1/4 turn clockwise to secure it in place.

Push the power connector on to the base of the new bulb until it clicks into place. Tug on the power connector to ensure that it is attached securely.

Then carefully pull the bulb straight out of the socket. Replace the turn signal / parking light bulb with a new # 3457A bulb.

Replace the side marker bulb with a new # 2825 bulb. Insert the new bulb back into the headlight assembly and rotate the base 1/4 turn clockwise to secure it.

To do this, remove the single 10mm bolt that holds it in place on the side of the engine bay.

(Accessing the driver side high beam bulb should be easily done by removing the car battery.)

To remove it, depress the black plastic tab on the power connector and wiggle it off.

Then rotate the base of the high beam bulb 1/4 turn counter clockwise and carefully pull it out of the headlight assembly.

Clean it with a alcohol moistened tissue if you do touch it.

Place the new bulb into the headlight assembly in the same position as the old one was removed and rotate the base 1/4 turn clockwise to lock it into place.

Tug down on the power connector to check that it is securely attached.

Then replace the coolant reservoir bottle and tighten the single 10mm bolt that holds it into place.

Activate the hazard lights to test both turn signals and flip on the high beams to test those bulbs.

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