Accessing the trunk is the first step in changing the brake light on a 2017 Hyundai Elantra. This allows you to reach the light assembly efficiently and safely. Once you have accessed the trunk, you can then proceed to replace the brake light bulb. Ensuring that your brake lights are functioning properly is essential for maintaining safety on the road.
It is important to follow the manufacturer's instructions carefully when changing the brake light on your Hyundai Elantra. This will help you complete the task correctly and avoid any potential issues with the new bulb. Remember to test the new brake light after installation to confirm that it is working correctly before closing the trunk.
Gather Your Tools

Before tackling the brake light change on your 2017 Hyundai Elantra, you'll need to gather a few critical tools. Don't worry, you won't need a garage full of mechanic's gear, but having the right items on hand will make the process smoother and quicker.
To start off, you'll need a Phillips screwdriver. This common tool is vital for removing the screws that hold the brake light housing in place. Make sure it's in good condition to avoid stripping the screws. Next, grab a flathead screwdriver. You'll use this to gently pry open the housing if it's a bit stubborn after unscrewing. Be gentle to avoid damaging the plastic.
You're going to need a new brake light bulb. Make it's the correct type for your 2017 Elantra; the manual or a quick online search should tell you what you need. It's a good idea to buy a couple, just in case one breaks or you find another light out.
Lastly, consider having some gloves handy. They'll keep your hands clean and protect the new bulb from oils on your skin, which can shorten its lifespan. And while not a tool, good lighting can't be overstated. Whether it's a garage light or a portable lamp, you'll want to see what you're doing to avoid any mishaps.
With these items ready, you're all set to start the replacement process. Remember, preparation is key to a smooth and successful change.
Accessing the Trunk
To access the trunk of your 2017 Hyundai Elantra, initially make sure the vehicle is parked on a flat, stable surface and the engine is turned off. This guarantees your safety and the vehicle's stability while you're working.
Changing a brake light might seem intimidating, but with the right approach, it's quite simple. The initial step is getting into the trunk, where the magic happens.
Here's how you can smoothly access the trunk:
- Locate the Trunk Release Button: Inside your Elantra, you'll find the trunk release button usually positioned near the driver's seat, often on the floor to the left or on the lower dashboard. Pressing this button will release the trunk, allowing you to proceed.
- Use Your Key Fob: If for some reason, the interior button isn't an option, your key fob is your next best friend. There's a trunk release button on it. A long press should open the trunk without much difficulty.
- Manual Key Access: In the rare case that the electronic options aren't working, you can always rely on the traditional way. Your Elantra's key set includes a physical key that fits into the trunk lock. Insert it, turn, and you've got access.
Removing the Light Assembly

Once you've accessed the trunk, you'll need to remove the light assembly to change the brake light. This might seem challenging at first, but with a bit of patience, you'll get through it without a hitch. Initially, you'll spot several fasteners, typically plastic nuts or screws, securing the brake light assembly to the car's body. You'll find these on the inside of the trunk, right behind the brake light itself.
To start, grab a suitable tool, like a wrench or a screwdriver, depending on the type of fasteners your Elantra uses. You're going to loosen and remove these fasteners. It's important you keep these safe as you'll need them to reattach the light assembly later.
Next, gently pull the light assembly away from the car's exterior. You might feel a bit of resistance here since there are often clips or pins holding it in place along with the fasteners you've already removed. It's important that you use gentle, but firm pressure to avoid breaking these clips.
Once you've successfully detached the assembly, carefully guide the entire unit out of its position. Be mindful of any wiring connected to the assembly. You don't want to tug or pull on these wires forcefully. In some models, you'll need to disconnect the wiring harness to completely free the light assembly. This usually involves pressing down on a tab to release the connector.
And there you have it — you've successfully removed the light assembly from your Hyundai Elantra, making it ready for the next step.
Replacing the Bulb
With the light assembly removed, it's time to focus on replacing the brake light bulb in your Hyundai Elantra. This process is relatively simple and requires only a few steps to make sure your brake lights function correctly, guaranteeing your safety and compliance with road regulations.
Initially, you'll need to identify the correct replacement bulb for your 2017 Hyundai Elantra. The vehicle manual should list the specific type, or you can check with a trusted auto parts retailer to get the exact match. Once you have the correct bulb, follow these steps to install it:
- Remove the Old Bulb: Gently twist the bulb socket counterclockwise to free it from the light assembly. Pull the socket out slightly and press down on the bulb, turning it counterclockwise to release it. Carefully remove the old bulb from the socket. It's vital not to force it, as this could damage the socket or assembly.
- Insert the New Bulb: Take your new brake light bulb and insert it into the socket. You'll want to avoid touching the glass part of the bulb with your fingers, as oils from your skin can shorten the bulb's lifespan. Push the bulb into the socket and twist it clockwise until it's securely fastened.
- Reattach the Bulb Socket: After the new bulb is in place, align the socket with the opening in the light assembly. Insert it and twist clockwise until it locks into place. Make sure it's snug and properly aligned to prevent any issues with the light's operation.
With the new bulb installed, you've successfully replaced your Hyundai Elantra's brake light bulb. This straightforward task can save you a trip to the mechanic and keep your vehicle safe on the road.
Testing the New Light

After installing the new brake light bulb, it's crucial to test it to make sure it's working properly. This step guarantees your safety and that of other drivers, as a functional brake light signals your intentions on the road. Here's how to do it effectively.
Initially, you'll need a friend or a reflective surface. If you've got someone to help, ask them to stand behind your Hyundai Elantra while you press the brake pedal. If you're alone, park your car facing a reflective surface, like a large window or a garage door, so you can see the reflection of your brake light when you press the pedal.
Next, turn the ignition to the 'ON' position, but you don't need to start the engine. Press the brake pedal down and hold it. Your helper should confirm if the new brake light illuminates. If you're using a reflective surface, you should be able to see the light yourself.
If the light doesn't turn on, don't panic. Initially, check to make sure the bulb is properly installed and that it's the correct type for your Elantra. Additionally, double-check the fuse related to the brake lights. It might've blown and needs replacing.
Once you've confirmed the light works, you can breathe a sigh of relief. You've successfully changed your brake light bulb, ensuring your Elantra is safe and compliant with road safety regulations. Remember, regular checks on your vehicle's lighting are crucial, so make this a part of your routine car maintenance.
Conclusion
You've just learned how to successfully change the brake light on your 2017 Hyundai Elantra. By gathering the right tools, accessing the trunk, removing the light assembly, and replacing the bulb, you've tackled the task with ease.
Now that you've tested the new light to make sure it's working perfectly, you can drive safely knowing your brake light is fully functional. Remember, maintaining your vehicle's lights is important for your safety and those on the road with you.
