In most 2013 Impreza models, you’ll be dealing with standard halogen headlights using H11 low-beam bulbs and 9005 high-beam bulbs, with fog lights typically using H11 if your model is equipped. Some trims or regional variants offered HID headlights as an option.
Below is a breakdown of the common halogen setup and how to determine whether your car has HID headlights, plus guidance for bulb replacement.
Standard halogen headlights (US-market 2013 Impreza)
The following bulb types apply to the typical halogen headlight system found on most base and premium US-spec 2013 Impreza models.
- Low-beam headlight bulb: H11
- High-beam headlight bulb: 9005 (HB3)
- Fog light bulb (if your model is equipped with fog lamps): H11
Note: Some trims may lack fog lights or may have different configurations in specific markets.
Optional HID headlights and identification
For certain trims or regional models, HID headlights were offered. This section explains how to tell if your Impreza has HID and what that means for bulb replacement.
How to tell if you have HID headlights
Look for projector-style headlamps with a distinctive bluish tint or a badge indicating HID on the headlamp unit. If the sockets you access under the hood show no H11 or 9005 markings, and you see a ballast in the wiring, you likely have HID.
- HID systems use dedicated bulbs (variously labeled as D1S, D2S, etc.) and require a ballast; they are not direct bulb swaps from halogen.
- Replacement bulbs, ballast, or entire headlight assemblies are typically needed through a dealer or automotive lighting specialist; direct halogen bulbs like H11/9005 will not work in a HID-only housing.
- Exact bulb type and replacement procedure vary by market and trim level; verify with your owner's manual or Subaru dealer.
In short, if your Impreza is equipped with HID headlights, follow the specific replacement guidance for HID systems rather than standard halogen bulbs.
Summary
The 2013 Subaru Impreza primarily uses halogen headlights (H11 low beam, 9005 high beam) with H11 fog lights on equipped models. HID headlights were available on some trims/markets; those setups require different bulbs and a ballast. Always confirm your exact bulb type by checking the owner’s manual, the door jamb sticker, or with a Subaru dealer before purchasing replacements.
