Understanding Your Brake Light System
Before diving into the replacement process, it’s essential to understand the basic components of your Hyundai Elantra’s brake light system. The brake lights are typically composed of:
1. Brake Light Bulbs
These bulbs are responsible for illuminating the brake lights. They come in various sizes and types, so it’s crucial to identify the correct bulb for your Elantra. Consult your owner’s manual or an online parts catalog to find the exact bulb specifications.
2. Brake Light Assemblies
The brake light assemblies are the housings that hold the bulbs and lenses. They are usually integrated with the taillights and can be found on the rear of your vehicle.
3. Wiring Harness
The wiring harness connects the brake light bulbs to the vehicle’s electrical system. It transmits the electrical current from the brake pedal switch to the bulbs when you apply the brakes.
4. Brake Pedal Switch
This switch is located under the brake pedal and sends a signal to the vehicle’s electrical system when the brake pedal is pressed. This signal activates the brake light bulbs.

Step-by-Step Guide to Replacing a Brake Light
Now that you’re prepared, let’s walk through the steps involved in changing a brake light on your 2017 Hyundai Elantra:
1. Locate the Brake Light Assembly
The brake light assembly is typically located on the rear of your vehicle, integrated with the taillight assembly. Open your trunk or hatchback to access the rear of your Elantra.
2. Access the Bulb Socket
Examine the brake light assembly and locate the bulb socket. It’s usually a plastic or metal housing that holds the brake light bulb. Depending on your Elantra’s model, you may need to remove a few screws or clips to access the bulb socket.
3. Remove the Old Bulb
Once you have access to the bulb socket, gently twist the old brake light bulb counterclockwise to remove it. Be careful not to touch the glass part of the bulb with your bare hands, as this can shorten its lifespan. If the bulb is stuck, you may need to use a gentle twisting motion or a rubber grip tool to loosen it.
4. Install the New Bulb
Carefully insert the new brake light bulb into the socket, aligning the pins or grooves on the bulb with the corresponding slots in the socket. Twist the bulb clockwise until it is securely in place. Do not overtighten the bulb, as this can damage the socket.
5. Reassemble the Brake Light Assembly
Once the new bulb is installed, reassemble the brake light assembly by replacing any removed screws or clips. Make sure everything is securely fastened.
6. Test the Brake Lights
Before closing your trunk or hatchback, test the newly installed brake light by applying the brakes. You should see the brake light illuminate clearly. If the brake light is not working, double-check that the bulb is securely installed and that the wiring harness is properly connected. (See Also: Which Brake Fluid For My Car Uk? Ultimate Guide)
