What is the model number of the Subaru Outback's low beam headlight?
2 Answers
Subaru Outback's low beam headlight model is D2S (original xenon lamp), high beam: 9005 (HB3). Introduction to high beam: The intensity of the light is adjusted based on the distance of the filament. The high beam is at its focal point, emitting light that is parallel and more concentrated, with greater brightness, capable of illuminating distant and high objects. Introduction to low beam: The low beam is outside its focal point, between 1 to 2 times the focal distance, emitting light in a divergent state, capable of illuminating a larger area of nearby objects. The low beam's illumination distance is approximately 30-40 meters.
I'm familiar with the Subaru Outback, and its low beam bulbs are typically the H11 type, especially common in models from 2010 onwards. Having driven for many years, I make it a habit to regularly check the lighting system to avoid nighttime driving risks. H11 bulbs are designed for durability, but their lifespan is roughly 500 to 1,000 hours, requiring periodic replacement. If you notice dimming or flickering lights, it may indicate bulb aging. Nowadays, many opt to upgrade to LED or HID bulbs for enhanced brightness, but when replacing them, ensure the wattage and voltage match the factory specifications to avoid damaging the circuit. I also recommend checking the owner's manual or the label under the hood to confirm the exact bulb type, as there might be slight variations between production years—for example, the 2015 model uses H11, while the 2018 version remains compatible. For maintenance, it's best to perform bulb checks or replacements with the engine turned off.
