How to Change Headlight Bulb

The importance of properly functioning headlights cannot be overstated. As much as they are an operational feature of your vehicle, they are also a part of your car that ensures your safety, and the safety of other drivers and pedestrians on the road.

Many times, when one of the headlight bulbs gives out, drivers decide to keep driving guided by the illumination of just one bulb. As possible as it may seem, driving with only one functioning headlight is not advisable at all.

With that said, car headlight bulbs can go bad at any time, and for a number of reasons. Thankfully, you don’t need a professional’s help to replace a bad headlight bulb. You can simply order a cheap and durable bulb online and replace it yourself. 

In fact, it is advisable to check cheaper headlight reviews and order a few spare bulbs that you can keep in your car’s glove compartment.

Once you have the replacement bulbs for your headlight, you can follow these steps to replace the bad bulb with a new one:

Step 1: Turn Off Ignition And Disconnect The Battery

The first step is to park your car in a safe place and turn off the ignition. Once this is done, pop the hood of your car and disconnect the battery. 

Doing so is very simple. Simply locate the negative (-) terminal on the battery, loosen the bolt, and remove the wire connected to the negative terminal.

Step 2: Locate The Bulb Holder

You will be able to access the bulb holder from the rear side of the headlight, which you can find in the engine bay of your car. In some cars, the bulb holder is easy to reach but in others, it might be obstructed by other parts of the car like the battery or the air filter. 

If this is the case, you may need to remove these parts in order to reach the battery. While it’s surely a bit of extra work, it is perfectly doable and you should not be discouraged.

Step 3: Remove The Old Bulb

Once you have cleared the way to reach your bulb holder, you will see three wires clamped into the bulb. Carefully remove these wires. In most cases, these wires are either held in place by screws, or a metal clip, or a plastic catch with a lever.

For the plastic catch, you will need to push down the lever and pull the wires out. For wires held together with metal clips, you can simply (gently) pull them out. For wires held together by screws, you will need to unscrew them using a screwdriver. In most cases, the wires of a headlight bulb are fragile and thus, should be handled with extreme care.

Once you have removed the wire, you should be able to remove the rear part of the headlight holder. Once you do that, you can simply pull the bulb out from it.

Step 4: Install The New Bulb

Now all that is left to do is install the new bulb. You can simply take the new bulb and fix it into the back panel of the headlight holder. Make sure you use gloves or tissues to handle the new bulb to ensure it is clean when it is installed.

Once done, fix the rear panel in place and reconnect the wires. Now, reconnect the battery and test the new bulb. If everything works fine, you can close the hood and call it a day.

If you had to remove certain engine fluid holders or the battery to reach the headlight, make sure you reattach those parts properly.


Changing a headlight bulb is a simple process and doing it yourself can save you up to $100. We hope that you found these tips useful.
