2017 Subaru Outback Headlight Bulb Size
Subaru pushed the fifth-generation Outback further into tech territory for 2017, adding lane keep assist and adaptive headlights on the Touring trim, and knowing the 2017 Subaru Outback headlight bulb size is essential before ordering an upgrade. The low beams take H11, the high beams use 9005, and the fog lights accept H16 bulbs. Halogen headlights remain standard on the 2.5i base, while Premium and higher trims can include factory LED units. Upgrading to 2017 Subaru Outback LED headlights is the fastest way to close the gap between halogen-equipped trims and the premium models.
The 2017 refresh brought a more tech-forward cabin with improved infotainment and additional driver-assistance features. Brighter low beams complement the lane keep assist and EyeSight systems by giving you more forward illumination on dark two-lane roads. All HID Nation kits ship free and come with a lifetime warranty, making it a straightforward decision for Outback owners who want modern lighting output without a dealership price tag.
Choosing LED or HID for the 2017 Subaru Outback
An LED conversion kit drops into the 2017 Outback's H11 low beam socket without any wiring changes. The bulb locks into the factory retainer, and the external driver mounts behind the housing with enough clearance for the dust cover to seal properly. Full brightness is available from the moment you turn the headlights on, producing a clean 6000K white that completely replaces the yellowish halogen glow.
HID kits for the 2017 Outback pair each H11 bulb with a ballast that delivers a broader, more concentrated beam spread. The warm-up period lasts only a few seconds, and at full power the xenon arc reaches further down the road than LED at equivalent wattage. Many Outback owners who tow trailers or commute on unlit county highways prefer HID for the extra throw distance.
HID Nation backs every kit with free shipping and a lifetime warranty. If anything fails, we send a replacement at no charge.
Frequently Asked Questions
What is the 2017 Subaru Outback headlight bulb size?
The 2017 Subaru Outback headlight bulb size is H11 for the low beams, 9005 for the high beams, and H16 for the fog lights. Base 2.5i models use halogen headlights, while Premium, Limited, and Touring trims may include factory LED low beams. Both the 2.5i and 3.6R use the same bulb sizes across all lighting positions.
Will LED headlights affect the 2017 Outback's adaptive headlight system?
No. The adaptive headlight feature on the 2017 Outback Touring trim operates by physically tilting the headlight housing as you steer. This mechanical function is independent of the bulb type inside the housing. An LED or HID conversion bulb works normally within the adaptive assembly and continues to follow steering input just as the factory halogen does.
How long does it take to install LED headlights on a 2017 Subaru Outback?
Plan on 15 to 25 minutes for both low beams. Access the H11 sockets from behind the headlight housing in the engine bay, twist the retainer counterclockwise, and swap the old halogen for the LED bulb. The compact LED driver tucks into the space behind the housing. No bumper removal or wheel-well liner work is required on the 2017 Outback.
Is the 2017 Outback headlight bulb the same as the 2015 model?
Yes. The 2015 through 2019 Subaru Outback all share the same fifth-generation platform and use identical headlight bulb sizes: H11 low beam, 9005 high beam, and H16 fog light. A kit that fits the 2017 will also fit the 2015 and 2018, so parts are easy to source and cross-reference.
What color temperature should I choose for 2017 Outback LED headlights?
Most 2017 Subaru Outback LED headlights come in 6000K, which produces a bright, crisp white that closely matches the factory LED output on higher trims. This color temperature offers the best balance of visibility and contrast on both wet and dry road surfaces. Some owners prefer a slightly warmer 5000K for better performance in heavy fog or snow, but 6000K is the most popular choice overall.
