The Forester’s headlight bulb setup in 2015 most commonly relies on halogen bulbs: H11 for low beams, 9005 for high beams, and H11 for fog lights. Some trims offered factory HID headlights, which use xenon bulbs with a ballast rather than standard halogen bulbs. This article breaks down the typical configurations and how to confirm what yours uses.
Halogen headlight setup (common configuration)
This section covers the traditional halogen lighting arrangement found on many 2015 Forester models. Bulb choices can vary by trim and market, but the following list reflects the most widely installed halogen configuration.
Bulb types by function
- Low beams: H11
- High beams: 9005 (HB3)
- Fog lights: H11
The list above covers the standard halogen setup used on many 2015 Foresters. To be certain of your exact bulb types, consult the owner's manual, the bulb label on the inside of the driver's door jamb, or inspect the existing bulbs for markings.
HID headlights (optional on some trims)
Some 2015 Forester models offered factory HID headlights. These do not use the same halogen bulbs as the standard setup and require xenon bulbs paired with a ballast.
What to expect with HID
- Bulbs: Xenon HID bulbs (commonly from the D2S/D3S family) with an accompanying ballast
- Identification: HID systems often have a ballast module near the headlight; the bulbs themselves will not be labeled H11 or 9005
- Replacement: Replacing HID bulbs typically involves the correct ballast-compatible bulb and may require professional service
If your vehicle is equipped with HID headlights, use the bulb type specified for your trim/year. Halogen bulbs cannot be used in HID housings.
How to verify your specific car
Because bulb configurations vary by trim and region, the quickest way to confirm your exact bulb type is to check these sources.
- The owner's manual, which lists bulb types for low beam, high beam, and fog light locations
- The headlight assembly itself for bulb markings or model numbers
- The driver’s door jamb sticker or VIN-based Subaru service documentation for exact specifications
When in doubt, contact a Subaru dealer or a qualified automotive technician with your VIN to obtain the precise bulb specifications for your car.
Summary
For the 2015 Subaru Forester, the typical halogen configuration uses H11 for low beams, 9005 for high beams, and H11 for fog lights. Some trims offered factory HID headlights, which rely on xenon bulbs paired with ballast (not interchangeable with halogen bulbs). Always verify the exact bulb type for your vehicle via the owner’s manual, the bulb markings, or your dealer using your VIN to ensure a correct and safe replacement.
