The 2010 Subaru Forester mainly uses halogen bulbs: H11 for the low beams, 9005 for the high beams, and H11 for fog lights when the vehicle is fitted with them. Some markets or trims may vary, and optional HID setups exist on certain models. Check your specific car’s manual or the bulb label to be certain.
Headlight bulb types by function
The following breakdown covers the typical halogen setup found on most 2010 Foresters. Sizes can vary by trim or market, so verify on your exact vehicle.
- Low beams: H11 halogen bulbs (55W, single filament). These power the standard projector low-beam setup common on 2010 Foresters.
- High beams: 9005 halogen bulbs (HB3) (65W). Used for the brighter forward lighting when high beams are engaged.
- Fog lights (if equipped): H11 halogen bulbs. Many Forester models with fog lamps use the same H11 bulb type as the low beams.
Note: If your Forester has factory HID headlights instead of halogen, the bulbs will be xenon types (for example D2S/D3S) and are part of a ballast system rather than simple replaceable halogen bulbs.
Confirming the right bulb for your exact Forester
To be absolutely sure you order the correct bulbs for your specific vehicle, follow these steps.
- Consult the owner's manual or service manual for the exact bulb sizes listed for your trim and market.
- Check the bulb label on the bulb itself after removing it from the headlight assembly—many bulbs have the size printed on the base.
- Look for a sticker under the hood or on the driver's door jamb that lists bulb sizes for headlights, high beams, and fog lights.
- If you’re unsure, contact a Subaru dealer or use an online parts catalog with your VIN to verify exact bulb types and compatibility.
Using these steps will help you confirm the correct bulb type and prevent ordering the wrong part.
Upgrade considerations and maintenance tips
If you’re considering brighter or alternative lighting, plan for compatibility and safety. Halogen bulbs are straightforward replacements, while LEDs or HID upgrades require additional components (ballasts, wiring adapters, CAN-bus considerations) and may affect warranty or compliance.
- Bulb compatibility: Ensure any upgrade matches the socket size and fits within the headlight housing without causing contact with lenses or electrical components.
- Legal and safety: Check local regulations on headlight color and intensity; some non-halogen upgrades may require inspection or certification.
For complex upgrades, consult a professional installer to avoid misalignment or electrical issues.
Summary
For most 2010 Subaru Forester models, the standard halogen setup uses H11 for low beams, 9005 for high beams, and H11 for fog lights where equipped. Always verify exact sizes on your vehicle via the manual, vehicle label, or dealer resources, especially if your car has a market- or trim-specific option like HID headlights. Upgrading to LEDs or HIDs involves additional considerations and professional installation is recommended.
