Note: Some higher trim levels of the 2019 Forester came equipped with full LED headlights from the factory. For these models, individual bulb replacement is generally not possible for the low and high beams, as they are integrated LED units.
The 2019 Subaru Forester offers a fantastic blend of capability, safety, and modern features. For many owners, maintaining optimal visibility and style means keeping the lighting system in top shape. Whether you're looking to replace a burnt-out bulb or considering an upgrade, knowing the correct bulb sizes is essential. This guide covers the various bulb types and sizes for your 2019 Forester, helping you navigate replacements and potential upgrades.
OEM Lighting Variations
Subaru offered the 2019 Forester with different lighting configurations depending on the trim level. Lower and mid-tier trims typically came with traditional halogen bulbs for the headlights, fog lights, and DRLs. Higher trims, such as the Touring, often featured full LED headlight assemblies for both low and high beams, as well as LED DRLs. When your Forester has factory-installed LED headlights, the individual low and high beam bulbs are not designed to be replaced separately; the entire headlight assembly would need service if there's an issue with the LED units.
For models with halogen headlights, the low beams commonly use an H11 bulb, and the high beams use an H9 bulb. Fog lights usually take an H16 or PSX24W bulb. DRLs in halogen-equipped Foresters often use a 9005 bulb, sometimes running at a lower voltage for the DRL function.
LED vs Halogen Upgrade Considerations
Upgrading your 2019 Subaru Forester's halogen bulbs to LEDs can provide significant benefits, including brighter light output, a crisper white light, and longer lifespan. However, it's not always a straightforward swap. Here are key considerations:
