What Are the Parts of a Headlight Assembly?

The headlight assembly is more than just a lens and a bulb. It includes multiple components that keep your vision clear and your vehicle safe. Knowing what each part does can help you choose the right exterior lighting solution.

Essential Headlight Parts You Should Know

3. Fog Lamp Bulb

Mounted low on the bumper of your Jeep Grand Cherokee, this bulb cuts through fog, rain, and snow to improve close-range visibility.

4. Signal Lamp Bulb

This bulb flashes on either side of the headlight assembly to indicate turns or lane changes.

5. Run Lamp Bulb

Also known as daytime running lights, these bulbs remain on during the day for added visibility and safety.
