2015 Subaru Outback Headlight Bulb Size
The 2015 Subaru Outback launched an all-new fifth generation that blurred the line between wagon and SUV, and getting the 2015 Subaru Outback headlight bulb size right is the first step toward a meaningful lighting upgrade. The low beams use H11 bulbs, the high beams take 9005, and the fog lights run H16. Base 2.5i trims shipped with halogen headlights, while Premium and above offered factory LED low beams. Whether you chose the naturally aspirated four-cylinder or the 3.6R flat-six, upgrading to 2015 Subaru Outback LED headlights transforms nighttime visibility for a vehicle built around outdoor adventure.
Subaru designed the fifth-gen Outback for skiers, bikers, kayakers, and anyone else who loads up before dawn and drives home after dark. EyeSight driver-assist became available on Premium and higher trims, and brighter headlights complement that system by giving you better forward vision. HID Nation ships every kit free with a lifetime warranty, so the upgrade carries zero risk.
LED and HID Headlight Options for the 2015 Subaru Outback
LED conversion kits for the 2015 Outback slot directly into the factory H11 low beam socket with no rewiring or housing modification. You get full 6000K white output the instant you flip the switch, which is a noticeable improvement over the warm yellow halogen glow. The compact LED driver tucks neatly behind the headlight housing, and most owners wrap up both sides in about 20 minutes.
HID xenon kits deliver the densest beam pattern available for this platform. Each bulb pairs with a slim ballast that mounts in the engine bay, and after a brief warm-up the light output surpasses what LED provides at the far edge of the beam. If you regularly drive mountain roads or unlit rural highways, HID is worth the slightly longer installation time.
Every HID Nation conversion kit includes free shipping and a lifetime warranty. If a bulb or ballast ever fails, we replace it at no cost.
Frequently Asked Questions
What is the 2015 Subaru Outback headlight bulb size?
The 2015 Subaru Outback uses H11 bulbs for the low beams, 9005 bulbs for the high beams, and H16 bulbs for the fog lights. Base 2.5i models come with halogen headlights, while Premium and above may have factory LED low beams. This fitment applies to both the 2.5i four-cylinder and 3.6R six-cylinder models.
Can I install LED headlights on a 2015 Subaru Outback with EyeSight?
Yes. LED headlight conversion kits do not interfere with the EyeSight camera system on the 2015 Outback. The cameras are mounted at the top of the windshield and read the road ahead independently of the headlight bulb type. An LED or HID kit replaces only the bulb inside the existing housing and does not alter the beam pattern that EyeSight relies on.
Are 2015 Subaru Outback fog lights the same bulb as the headlights?
No. The 2015 Outback uses H16 bulbs for the fog lights and H11 bulbs for the low beam headlights. Although the H16 and H11 look similar, the H16 has a different tab arrangement and lower factory wattage. Order the correct size for each position to ensure a proper fit and optimal beam pattern.
How difficult is the headlight bulb replacement on a 2015 Outback?
The 2015 Outback provides decent access to the headlight housing from the engine bay. Open the hood, reach behind the headlight assembly, twist the bulb retainer counterclockwise, and pull the old H11 bulb out. Insert the new LED or halogen bulb, lock the retainer, and reconnect the harness. Most owners finish both sides in 15 to 25 minutes without removing any engine bay components.
Does the 2015 Outback share headlight bulbs with the 2017 or 2018 model?
Yes. The 2015, 2017, and 2018 Subaru Outback all belong to the same fifth generation and share identical headlight bulb sizes: H11 low beam, 9005 high beam, and H16 fog light. An LED kit purchased for any of these model years will fit the others, which is helpful if you own multiple Outbacks or are shopping the used market.
