Replacement tail light bulbs for the '11-'16 Elantra include the following with their part numbers: Brake # 2357, Turn Signal 1156A or 1156NA, Reverse 921 or W16W, and Parking or Rear Side Marker 168, 2825, 194 or W5W.

The only tools needed to replace any of the tail light bulbs include a Phillips head screwdriver, a 10mm socket and a ratcheting wrench.

Swing open the rectangular access panel inside the trunk and use a 10mm socket with a ratcheting wrench to remove the three black 10mm nuts that hold the tail light assembly to the rear of the vehicle.

Be very careful when removing the 10mm nuts as they are easy to drop down into the rear bumper. Use a magnetic socket if you have one available.

Turn it upside down and gently rest it on the bumper.

Place a towel in between the tail light and the bumper to prevent scratching the paint on the bumper or the plastic housing.

The bulbs can be identified by the color of their sockets as follows: Turn Signal - Light Grey, Parking - White, Brake - Red / Orange and Rear Sidemarker -  Light Tan / Yellow.

To remove the larger Brake or Turn Signal light bulbs, push them down into their sockets and rotate 1/4 turn counter clockwise before pulling them straight out.

To replace the larger brake and turn signal light bulbs, insert the bulb into the socket, push down and rotate it 1/4 turn clockwise to lock it in place.

Then insert any of the bulbs and sockets back into the tail light and rotate them 1/4 turn clockwise to lock them in place.

The replacement part numbers are as follows: Brake # 2357, Turn Signal 1156A, Reverse 921, and Parking / Rear Side Marker 168, 2825, 194, W5W or an LED.

Carefully push the tail light back on to the vehicle and spin on the three black metal nuts by hand.

Tighten the 3 nuts with the 10mm socket and ratcheting wrench to just past hand tight.

Then swing the access panel closed to complete the job.

Use a standard Phillips head screwdriver to unscrew the black plastic fasteners about 1/4 to 1/2 turn counter clockwise before pulling them straight out of the trunk lid carpet.

Turn the socket 1/4 turn counter clockwise and pull it straight out of the trunk lid tail light assembly.

Pull the old parking light bulb straight out of the assembly.

Replace it with a 2825 five watt T10 wedge base bulb (also known as part # 168 or 194).

Two of the 10mm nuts are accessible from the edge of the trunk lid and the other two are in the recessed cut out.

Rotate the light grey base of the reverse light bulb socket 1/4 turn counter clockwise and pull it straight out of the assembly.

Push a new # 921 or W16W light bulb straight into the socket, insert the socket back into the tail light housing and rotate it 1/4 turn clockwise to secure it in place.

Spin on the four 10mm nuts by hand to prevent them from becoming cross threaded and tighten them to just past hand tight with the 10mm socket and ratcheting wrench.

Turn the Phillips head screw inner piece of the fastener with the screwdriver clockwise (or just push it in with your finger) until it is flush with the outer part of the fasteners.

Test the new tail light bulb(s) by turning on the headlights, activating the hazard signals, and then have someone step on the brake pedal while placing the transmission in reverse.
