A burned-out headlight isn't just inconvenient—it’s a safety hazard and could even get you a ticket. Replacing a headlight is usually a simple task you can do yourself with minimal tools. Headlights are labeled with codes like H11, 9005, or H7, which refer to the bulb type and base design. These codes are often printed on the bulb or found in your owner’s manual. There are also different types of bulbs: **halogen** (most common), **LED**, and **HID (xenon)**. Always replace a bulb with one of the same type for compatibility.
Identify the Correct Bulb
Check your owner’s manual or the existing bulb for the correct type (e.g., H11, 9005). Make sure to buy the right replacement bulb for your car’s make and model.
Open the Hood and Locate the Headlight Assembly
Pop the hood and find the back of the headlight assembly. You’ll see a wiring connector going into a bulb socket—this is the part you’ll be removing.
Disconnect the Power Connector
Gently unplug the electrical connector by pressing the release tab and pulling it straight back. If it’s stuck, wiggle it gently—don’t force it.
Remove the Old Bulb
Twist the bulb socket counterclockwise (usually a quarter turn) and pull it out. Avoid touching the glass part of halogen bulbs, as oils from your skin can damage them.
Install the New Bulb
Insert the new bulb into the socket and twist it clockwise to lock it in place. Reconnect the power plug until it clicks securely.
Test the New Headlight
Turn on your headlights to make sure the new bulb is working. If it's not lighting up, double-check the connection or try flipping the bulb if it’s an LED (some only work in one orientation).
Repeat for the Other Side (Optional)
If one bulb has burned out, the other may be close behind. Consider replacing both at the same time for consistent brightness and lifespan.
Replacing a headlight is a quick and inexpensive fix that improves both your safety and visibility. Just make sure to use the correct bulb type and handle bulbs carefully—especially halogens. If your headlight housing is foggy or the bulb still seems dim, it might be time to clean or replace the headlight lens too.
