Replacing Headlights - Tips and Tricks


Want to change your headlights? Learn how to do the job the right way!

Many people have never replaced their own headlight bulbs and are a little intimidated by the job. But for the majority of cars, replacing the bulb of your headlight can be a simple task that takes less than a few minutes and requires no tools. Here are a few tips and tricks to make sure your headlight replacement runs correctly:

1. Find the Right Bulb

Make sure you get the correct replacement headlight bulb for your specific car, truck, or SUV. Choose between a direct replacement or upgrade with a wider light span or a brighter bulb.

2. Hands Off

Be careful to never touch the glass of a halogen headlight bulb. The oils from your hands can cause the bulb to burn out prematurely. Use latex gloves or a paper towel to handle the bulb, and if you accidentally touch the glass, wipe it down with isopropyl alcohol.

3. Grease to Last

Using a bit of dielectric grease on the base of the bulb will ensure it gets a good electrical contact, and it will help you get the full service life out of the headlight bulb.

4. Tool-Free

Most headlight bulbs can be reached and replaced without the use of tools, but make sure to take your time when removing and installing the light bulbs. If you're too rough, you may accidentally pull the wires out of the sockets or clips.

5. Read Up

Consult your owner's manual on where to find your bulbs and how to remove and install them. Some bulbs are held into the headlight assembly by the wiring socket assembly, while other bulbs are to be installed directly into the headlight assembly. Most headlight bulbs and socket assemblies are removed (and installed) with either a push-in-and-turn motion or by releasing small clips used to hold the pieces together.

6. Take Aim

Check the aim of your headlights. While driving, headlights can become loosened and knocked out of proper alignment due to rough road conditions. This can cause the light output of your bulbs to be directed away from the roadway. Pull your vehicle up to a garage door or wall and check to see that both headlights shine at the same angle. If you need to adjust the aim, consult your vehicle's owner manual or stop by Toyota of Greenville to have us adjust it for you.
