2014 Sentra Tail Light
Open Trunk Lid
Pry Up Center of Fastener
This automotive maintenance tutorial was specifically written to assist owners of the seventh generation (2013, 2014, 2015 and maybe also the updated 2016 and 2017 model years) Nissan Sentra sedan in changing a burnt out rear turn signal or reverse light bulb in the tail light housings.

Owners of other Nissan or Infiniti vehicles such as the Versa, Maxima, Juke, Rogue, Altima, Xterra, Pathfinder, Murano, Cube, Armada, Leaf, Quest, Frontier, Teana, 370Z, GT-R, Titan, G25, G37, M35, QX56, QX60 and M37 may also find these DIY instructions to be helpful.

The brake lights are LED bulbs that should last for the life time of the vehicle.

The replacement light bulb part numbers are as follows: Rear Turn Signal # WY21W (or 7440A and 7440NA) and Reverse Light # 921.

The tools needed to complete this procedure include a flathead screwdriver, a 10mm socket and a 1/4" drive ratchet.

Remove Pop Rivet Fastener
Trunk Carpet Liner
Pull Back To Access Housing
The first two steps are to open the trunk lid and then move to the side of the car with the burnt out tail light bulb.

Locate the black plastic pop rivet fastener on the grey carpeted trunk liner.

Gently pry up the center part of the fastener before pulling out the base of the fastener.

Pull back the trunk liner to access the tail light housing fasteners.

Two Tail Light Nuts
Pull Off Wire Harness
Loosen Counterclockwise
Pull the black plastic mount for the wiring harness off the lower bolt end.

Loosen the two nuts that secure the tail light housing in place by turning them counterclockwise with a 10mm socket and a 1/4" drive ratcheting wrench.

2nd 10mm Nut
Two 10mm Nuts Removed
Pull Off Tail Light Housing
Set the two nuts aside in a safe place.

Gently pull the tail light assembly straight off the rear corner of the vehicle.

Pry At Outer Edge
Turn Over Tail Light
1/4 Turn Counterclockwise
If you have trouble removing the tail light housing, gently pry all along the outer edge to release the friction fasteners.

There is a slot on the outer edge that slides over the top of a plastic pop rivet. Plus there is a metal peg or "spike" that gets inserted in to a grommet on the car.

Turn over the tail light housing to access the bulb sockets.

Reverse Light Bulb Socket
Pull Out Old 921 Bulb
Push In New # 921 Bulb
Rotate the small black plastic reverse light bulb socket 1/4 turn counterclockwise before pulling it straight out of the housing.

Pull the old bulb straight out of the socket and push in a new number 921 bulb.

If you would like to have brighter reverse lights, install some compatible replacement 921 LED bulbs.


1/4 Turn Clockwise - Lock
1/4 Turn Counterclockwise
Turn Signal Bulb Socket
Re-insert the reverse bulb socket in to the housing and rotate it 1/4 turn clockwise to secure it in place.

Rotate the grey plastic rear turn signal bulb socket 1/4 turn counterclockwise before pulling it straight out of the housing.

Pull Out Old 7440A
1/4 Turn Clockwise - Lock
Line Up Friction Fasteners
Pull the old light bulb straight out of the socket and push in a new amber colored number WY21W (also 7440A or 7440NA).

Re-insert the turn signal bulb socket in to the housing and rotate it 1/4 turn clockwise to secure it in place.

Line up the slot and the metal peg on the rear of the housing with the pop rivet and the grommet on the rear corner of the car.

Push On Tail Light Housing
Spin On 10mm Nuts
Tighten 10mm Clockwise
Push the tail light housing back in to place on the rear corner of the vehicle.

Move to the inside of the trunk and spin on the two 10mm nuts in the clockwise direction.

Tighten 2nd 10mm Nut
Push On Wire Harness
Push In Pop Rivet
Tighten the two 10mm nuts in the clockwise direction until they are snug.

Try to avoid over tightening the 10mm nuts to prevent from cracking the plastic tail light housing.

Re-insert the white plastic pop rivet on the trunk lid carpet liner back in to the hole near the bumper.

Replace Trunk Liner
Pop In Black Plastic Fastener
Test New Tail Light Bulbs
Push the trunk liner back in to place over the rear corner of the trunk.

Make sure the center piece of the black plastic fastener is raised.

Push the fastener back in to the trunk liner and pop in the center piece to secure it in place.

To test the new tail light bulbs, have someone step on the brake pedal, activate the hazard signals and place the transmission in reverse.

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