In most 2017 Kia models, brake lights are replaced by swapping a bulb inside the rear taillight housing; if your model uses LEDs, you may need to replace the entire tail-light assembly. This guide lays out the common approaches so you can do it safely and correctly.
Overview: bulb-based versus LED brake lights
2017 Kia vehicles vary in their brake-light design. Many trims use replaceable bulbs in the taillight assembly, while some higher-end or newer trims use LED brake lights that are not serviceable bulb-by-bulb. Confirm which system your car uses before starting to avoid unnecessary disassembly.
Bulb-based brake lights (typical on many 2017 Kia trims)
Use this step-by-step guide if your brake light uses a replaceable bulb. Gather the necessary tools and components before you start.
- Open the trunk and clear the cargo area so you can access the rear of the taillight.
- Remove the interior side panel or trunk liner that covers the taillight housing. This may require prying tabs or removing a couple of screws.
- Unfasten the taillight assembly from the body by removing the screws or clips that secure it, then carefully pull the assembly away from the car.
- Unplug the electrical connector from the back of the taillight by pressing the release tab and pulling straight out.
- Remove the bulb socket from the taillight by turning it counterclockwise (or releasing a retaining tab, depending on model).
- Take out the old bulb and replace it with a new bulb of the same type (common types are 3157, 3157A, 7443, or 7440). If you’re unsure, check the stamped bulb number on the old bulb or your owner’s manual.
- Reinstall the new bulb into the socket, reinsert the socket into the taillight, and reattach the taillight socket.
- Re-seat the taillight assembly into the body, reattach screws/clips, reconnect the wiring harness, and replace the trunk liner.
- Test the brake light by pressing the brake pedal with the ignition off, then verify in a shaded area or with a helper that both the tail and brake functions work.
With the bulb replaced, reassemble the trim and test the brake lights again to ensure proper operation.
LED brake lights (if your 2017 Kia uses LEDs)
Some 2017 Kia trims utilize LED brake lights that are not designed for bulb replacement. When LEDs fail, you typically replace the entire tail-light assembly. Here’s how to proceed safely.
- Identify the correct replacement tail-light assembly for your exact model and trim; consult the dealer, parts diagram, or owner’s manual to confirm the right part number.
- With the vehicle off, disconnect the negative battery terminal to minimize the risk of electrical shorts.
- Remove the interior trunk liner or access panel to expose the tail-light assembly.
- Undo the screws/clips securing the taillight unit, then carefully detach the wiring harness from the back of the unit.
- Remove the old tail-light assembly and install the new unit, reconnect the wiring harness, and secure with screws/clips.
- Reinstall the trunk liner, reconnect the battery, and test the brake lights to confirm proper operation.
LED tail-light replacements can be more complex and may affect warranty or require professional service. If you encounter moisture, damage, or fitment issues, contact a Kia dealer or reputable auto-electrician.
Safety tips and practical notes
Always ensure the vehicle is completely powered off and the keys are out of the ignition. Wear gloves or use a clean cloth when handling bulbs to avoid oils that can reduce bulb life. If you encounter corrosion, a stuck connector, or a broken lens, consider seeking professional assistance to avoid injury or water ingress.
Summary
For most 2017 Kia models with replaceable bulbs, the brake light is changed by removing the trunk-side panel, detaching the taillight, swapping the bulb, and reassembling. If the brake light is LED-based, the entire tail-light assembly is typically replaced rather than individual LEDs. Always verify the exact bulb type or part number from your owner’s manual or a parts diagram, and test the lights after reassembly to ensure full functionality.
Can I replace my brake light myself?
In most cases, you can simply twist the bulb socket slightly counterclockwise to remove. Install the new bulb. Apply a pea-sized drop of dielectric grease to the bulb, then insert into the socket. Re-attach the tail light housing.
