To replace a burned-out tail light on a 2019 Hyundai Elantra, access the rear light housing from the trunk, unplug the electrical connector, and replace the bulb if the model uses bulbs. If your version uses LED tail lights, you will typically need to replace the entire tail-light assembly rather than a single bulb.
Understanding the tail-light type in your Elantra
The 2019 Elantra comes in trims that may use traditional bulb-based tail lights or LED tail lights. Bulb-based systems let you swap individual bulbs, while LED systems generally require replacing the whole taillight assembly. Confirm which type you have by checking the old bulb, the owner’s manual, or the dealer’s specifications for your exact trim.
Bulb-type tail lights (common on many trims)
The following steps describe replacing an incandescent bulb inside a bulb-based tail-light assembly. If your vehicle displays LEDs, skip to the LED-specific instructions below.
Before starting this list, gather the right replacement bulb(s) and a few basic tools, and ensure the car is off with the ignition removed.
- Power down the car, set the parking brake, and open the trunk.
- Remove the interior trunk liner or access panel near the tail light to reveal the light housing and its fasteners.
- Disconnect the electrical connector from the tail-light bulb socket by pressing the release tab and pulling it away.
- Unscrew or unclip the tail-light housing retaining screws/nuts (usually 2–3) and carefully pull the assembly away from the body to access the bulb sockets.
- Turn the bulb socket counterclockwise (or release a locking tab) and pull it out to expose the bulb.
- Remove the old bulb and insert a new bulb of the same type, ensuring it sits firmly in the socket.
- Reinstall the bulb socket, reattach the tail-light assembly, reconnect the electrical connector, and secure the housing with its screws/nuts.
- Reposition the trunk liner or access panel and test the tail lights, brake lights, and turn signals before closing the trunk.
After completing these steps, you should have a functioning tail-light. If the light still does not illuminate, recheck the bulb type, reseat connectors, or inspect the fuse for the tail-light circuit.
LED tail lights (where applicable)
Some 2019 Elantra trims use LED tail lights. LED modules are not typically serviceable as a single bulb; they are replaced as a complete tail-light assembly. Follow these notes instead of bulb-based steps.
Before starting this list, prepare for a potentially larger repair and consider professional service if you’re not comfortable with the replacement.
- Power down the vehicle, engage the parking brake, and open the trunk to access the rear tail-light housing.
- Remove the interior trunk lining or panel to expose the tail-light mounting screws or fasteners.
- Disconnect the electrical connector from the tail-light assembly, noting how it’s routed for reassembly.
- Remove the screws or bolts securing the tail-light housing and gently pull the assembly away from the vehicle body.
- Detach the LED tail-light assembly from its mounting points and replace it with a new LED tail-light unit designed for your exact trim and model year.
- Reconnect the electrical harness, realign the new assembly, and secure it with the mounting screws/bolts.
- Reinstall the trunk liner, test all functions (running, brake, and turn signals), and ensure seals are properly seated to prevent moisture ingress.
LED replacements are typically covered under warranty if applicable and should be matched to Hyundai-part specifications for your exact configuration. If in doubt, consult a Hyundai service professional.
Additional safety and maintenance tips
Always handle bulbs with clean gloves or a tissue to avoid oil contamination, which can shorten bulb life. If you’re unsure about which bulb type to buy, consult the owner’s manual or check the old bulb for labeling. If anything feels stuck or you encounter wiring damage, stop and seek professional assistance.
Also, verify the vehicle’s fuses and relays related to the tail-light circuit if a replacement does not fix the problem; a blown fuse can mimic a bulb failure.
What to do after replacing the tail light
After finishing the replacement, reassemble all panels and trim, close the trunk, and perform a full light test in a safe area or garage. Check all modes—running, brake, reverse, and turn signals—to ensure proper operation and signaling to other drivers.
Summary
Changing a 2019 Hyundai Elantra tail light generally involves either swapping an incandescent bulb from behind the tail-light housing or replacing the entire LED tail-light assembly, depending on your trim. Bulb-based systems require accessing the trunk area, disconnecting the connector, removing the housing, replacing the bulb, and reassembling. LED-based systems typically require installing a new tail-light assembly. Always confirm the tail-light type for your exact vehicle, use the correct parts, test all functions after replacement, and consult a professional if you’re unsure.
