As you get ready to change your Toyota Corolla headlights? Here’s how to do it: 

  1. Get your tools

You’ll need to get all the necessary tools to get the job done first. There’s nothing worse than trying to get a job done, but you have to run back and forth because you’ve forgotten which tools are required. Here’s what you’ll need:

  1. Get the right bulb

Before we even think of getting started, it’s essential to ensure you have the right bulb for your car. It’s not too much of a task, and there are two ways to ensure you do it right: check your vehicle’s user manual, or you can go to your local Auto Mart store and ask them for the right bulbs for your 2020 Corolla. 

  1. Get the car into the correct position

Park your car on a flat surface and ensure the handbrake is up. Pop open the hood and ensure it’s supported so there’s no chance of it falling on you. 

  1. Locate the clip

Look for the clip at the back of the headlight that matches where your light plugs in. You might need to pair it up with the bulb’s location from the front. If there are any parts you need to remove to make the job easier, ensure they are easy to put back exactly how you found them. In general, there should be enough space to get your hands past the parts. Look for the electrical connection that attaches to the back of the bulb’s socket.

  1. Replace the old bulb

Push down on the tab that locks the connection, then pull it away from the bulb. Take out the old light bulb. You may need to remove a metal clip, rotate the bulb, or unscrew it in order to remove the bulb. Plug in the new bulb, and you’re almost done. 

  1. Backtrack your steps

Backtrack these steps to finish up with the replacement. Once everything is back in place, go ahead and test the headlamps to check if they are properly aligned and that they work.
