How to Change High Mounted Brake Light on Hyundai Elantra: 1 Minute to Replace Your Brake Light Easily

Changing the high mounted brake light (third brake light) on a Hyundai Elantra is a straightforward DIY task that doesn’t require advanced skills or tools. The high mounted brake light is crucial for vehicle safety, so it’s important to replace it promptly if it burns out. Here’s a step-by-step guide to help you get the job done efficiently:

1. Turn Off the Engine and Open the Trunk: For safety, ensure your vehicle is turned off and park it on a flat surface. Open the trunk to access the area behind the high mounted brake light.
2. Locate the Light Assembly: The high mounted brake light is usually mounted at the top center of your rear window inside the car or integrated into the trunk lid, depending on the model year. Consult your owner’s manual if unsure.
3. Remove the Interior Trim (If Necessary): On some Elantra models, there may be a trim cover or panel protecting the light assembly. Carefully pry it off with a flathead screwdriver or trim removal tool. Be gentle to avoid breaking any clips.
4. Disconnect the Wiring: Once you have access to the light housing, disconnect the electrical connector attached to the light bulb socket.
5. Remove the Old Bulb: Twist the bulb socket counterclockwise and pull it out. Remove the old bulb by pulling it straight out or by twisting it, depending on the bulb type.
6. Install the New Bulb: Insert the new bulb into the socket. Make sure it matches the required specification, typically found in your owner’s manual (usually a 921 or similar wedge bulb).
7. Reassemble: Reinsert the socket into the housing, twisting clockwise to lock. Reconnect the wiring, snap back the trim panel, and ensure all parts are secure.
8. Test the New Light: Ask someone to press the brake pedal or use a reflective surface to check that the new high mounted brake light illuminates properly.

If you’re undertaking other Hyundai Elantra DIY projects or planning to upgrade your vehicle’s interior in a more holistic way, consider how lighting enhancements fit into your overall home designer approach, balancing function and aesthetics for a cohesive look.

Tips 1:

When choosing a replacement bulb, opt for quality LED options for longer lifespan and brighter performance—they’re more energy efficient and require less frequent replacement. Also, always handle new bulbs with a clean cloth or gloves to avoid oil transfer, which can shorten bulb life.
