The 2018 Impreza uses H11 halogen bulbs for its low beam headlights. The H11 bulb size is a popular choice for many vehicles due to its compatibility and availability. It is important to note that different trim levels or optional packages may have different bulb sizes, so it’s always best to double-check the owner’s manual or use a bulb finder tool to ensure accuracy.

Replacing the Headlight Bulb

Now that you know the correct bulb size for your 2018 Impreza, here are the general steps to replace a headlight bulb:

1. Locate the headlight assembly: Depending on the specific Impreza model, the headlight assembly may be accessible from under the hood or behind the front wheel well.
2. Remove the connector: Gently disconnect the electrical connector from the back of the headlight bulb. This may require pressing a release tab or twisting the connector counterclockwise.
3. Remove the old bulb: Carefully remove the old bulb from the headlight assembly. Avoid touching the glass part of the bulb with your bare hands, as the oils from your skin can cause premature bulb failure.
4. Install the new bulb: Take the new H11 bulb and insert it into the headlight assembly. Make sure it is securely seated and aligned properly.
5. Reconnect the electrical connector: Plug the electrical connector back into the new bulb until it clicks into place.
6. Test the new bulb: Turn on your headlights to ensure the new bulb is functioning correctly.
