The headlight bulbs of your vehicle may go out eventually and need to be replaced. It could be due to overheating, running in extreme temperatures, or just because being old. No matter what the reason is, losing the illumination from your headlights is dangerous. Luckily, changing the headlight bulb is one of the easiest tasks to do when it comes to automotive replacement. 
You do not require any professionals to help or any complicated tools. In this article, we are going to check out how to change a headlight bulb with ease.

How To Change Headlight Bulb In 5 Steps

Things You May Need Before Replacing Headlight bulbs:
- New headlight bulb(s)
Make sure that you have the correct bulb size for your make and model. You can identify the headlight bulb size for your vehicle from the owner's manual. 
If you can't find your owner's manual, you can use the bulb size finder from SuncentAuto. Simply enter the make, model, and year of your car, and you can quickly find the compatible headlight bulbs for your vehicle.
- Wear gloves & goggles
Replacing a headlight is not a very risky activity, but it is sensible to be proactive about safety. Plus, headlight bulbs are so sensitive that oil stains or even fingerprints may trigger bulb premature burnout. 
So be sure to wear gloves to avoid stains on the bulbs and wear eye protection for your safety.
After having everything you need before the replacement, let’s get into the process.
While precisely changing the headlight is different depending on the year, make and model of your vehicle, there are a few universal steps to follow.

Step 1: Power Off Your Car

For your safety, turn off your vehicle and remove the key from the ignition. It’s also a good idea to disconnect the battery with your car cooled down.

Step 2: Open the Hood and Locate the Light

After making sure your car is off, open the hood, locate the back of the headlight and gain access to the bulb. The process of accessing the bulb isn’t always easy and it’s different for every vehicle. If you can’t find it, you can check the diagrams in your owners’ manual.

Step 3: Disconnect the Headlight Power Wires

You will find a plug with three wires at the base of the headlight, which is called the bulb connector. Depending on the vehicle, there are three mechanisms to keep them in place: a plastic catch, a metal clip or a screw cap. Here’s how to identify and disconnect it:
- Plastic catch: It has a plastic tab that sits on the connector at the base of the bulb, where it plugs into the wiring harness. Find the small lever at the top of the plastic catch, then push down on it while you pull the plug out.
- Metal clip: It’s a paperclip-like device that holds the bulb. Hold onto the metal clip, then pull it up and away.
- Screw cap: It’s a round, plastic cap that looks like the lid of a coffee mug. You can turn it counterclockwise to unscrew it.

Step 4: Remove the Old Bulb

After removing the back of the headlight holder, simply grab the bulb by the base and slowly pull it out. You may have to turn the bulb counter-clockwise slightly to free it from its socket. Keep the bulb aside safely, so that it doesn't break and you do not shatter glass all over. 

Step 5: Install the New Bulb Carefully

Remember to keep the gloves on when you touch the new bulb. While you can simply go ahead and install the new bulb, it would be better if you can use an alcohol wipe to clean it before installation.
Now, insert the new headlight bulb into the socket that previously held the old bulb. Then, plug it into the connector by reversing the procedure in Step 3. After that, shut the hood and you are good to go!

Step 6: Test the Bulb

Turn on your headlights to check whether your new bulb is working properly. Please make sure that you test the headlights before taking them on the road for a drive.

Tips for You When Replacing a Headlight

1. Avoid touching the bulb’s glass with your bare hands. It can cause the bulb to burn out quickly. 
2. Choose a clean space to work on your vehicle like a garage or driveway that is neat. Make sure there is enough light for you to work. 
3. While the task can be done within an hour, keep ample amount of time in your hand to do the job patiently. It might seem like a piece of cake but at the same time, you might even get hung up on some steps. Go slow and be patient. 
4. Keep a jar handy to put all your clips or screws. This way, they will remain safe and you can put them back.

What to Do If Your Headlight Bulb Doesn't Work?

If your replacement bulb doesn't seem to be working, turn off the car and make sure the connector is not loose.
If the connector is firmly plugged in but the headlight bulbs still not working, there may be a problem with the wiring and fuses. The wire may be broken somewhere or got pinched, causing no power going to your light.
If you've changed a halogen bulb, you should also check whether the bulb was suitable for your plug. If the new halogen bulbs run very hot, the stock plug may not handle the extra wattage, resulting in a bad connection. If this is the case, then you might have to change the socket rather than just changing the bulb.

What to Consider When Selecting Bulbs for Your Vehicle?

Here are some factors to consider when you looking for the best LED headlight bulbs for your vehicle:
Lifespan. Look for the lifespan of the bulbs. If you choose LED bulbs, then they will be your companion for more than a decade. 
Visibility area. Make sure that the bulbs provide superior visibility and don't leave any shadows or dark spots.
Color temperature. The color temperature of the bulb throws a certain shade of light. For instance, below 6000k, you might get a yellowish shade while at 6500k is whiter. If you choose a cooler white shade, then it will throw focused light on the road, which will make it clearly visible.
