Subaru Legacy Forward Lighting Information

2017-2018 Subaru Legacy Forward Lighting Information

April 2018 Update: The 2018 Subaru Legacy will be part of the same production generation as the 2016 and 2017 models, so it will likely use the same light bulb types. We look forward to being able to recommend the best HID and LED Kits/bulbs for your vehicle, so keep an eye on our Vehicle Lighting Guide for lamp replacement information when it becomes available.

The 2017 Subaru Legacy uses all the same bulb fitments as the 2015-2016 models, so nothing has changed as far as your upgrade options for forward lighting. New from us is the vehicle-specific 2017 Subaru Legacy HID Bulbs Pak, which has all the D4S options for your factory HID needs. For the factory H11 Halogen projector headlights, you can go with our 2017 Subaru Legacy HID kit for the brightest upgrade - Philips 4300K bulbs will give you the brightest, whitest, most OEM-looking headlights. Your Fog Lights are either H11 or H16, depending on whether you have the Eyesight Package or not, and one of the best upgrade options will fit both: The Philips LED Fog Light Bulbs are available in Yellow H16/H8/H11 Philips LED or White H11/H8/16 Philips LED.

2015-2016 Subaru Legacy Forward Lighting Information

The Subaru Legacy is all new for the 2015 model year. Check out our new 2015 Subaru Legacy lamp replacement guide or our 2016 Subaru Legacy lamp replacement guide for lots of options. The 2015 Subaru Legacy uses an H11 halogen bulb for the Low Beam and 9005 halogen bulbs for the High Beam – assuming your vehicle is equipped from the factory with standard halogen lights. Higher end trims are available with factory HID’s as an option, using a D4S HID bulb for the Low beam and 9005 halogen bulbs for the High Beam. If you’re lucky enough to have the factory HID’s, consider upgrading to the OSRAM D4S CBB HID bulbs; these bulbs offer up to a 7000K color temperature while offering comparable output to a stock 4300K bulb.

The 9005 High Beam bulb on the 2015 Legacy is also used as a Daytime Running Light. XenonDepot has a wide selection of 9005 replacement halogen bulbs from Philips, OSRAM, and Nokya. The Low Beam can be upgraded with either an H11 LED Headlight Kit, or an H11 HID Kit if you want maximum light output – going with a 4300K color temperature gets you the most similar functionality/looks to stock HID.



2009-2014 Subaru Legacy Forward Lighting

Although the styling changed, the bulb types stayed the same as fourth generation Subaru Legacy (2005 – 2009). The fifth generation Subaru Legacy continued to use an H7 halogen bulb for Low Beam and 9005 halogen bulb for the High Beam. Get maximum light output (up to 3 times brighter than halogen) from the Low Beam by upgrading with an H7 HID Kit. We also offer 9005 LED Headlight Kits that are a good upgrade over the standard halogen bulbs. 9005 LED High Beam bulbs are the best option if you want to improve your High Beam’s light output, as HID’s have a warm up time when first ignited - not ideal for a separate High Beam application. 9005 LED’s feature “instant on” functionality, so there’s literally no delay when you turn your High Beams on. Take a look at our 2014 Subaru Legacy Lamp Replacement guide more information about the HID, halogen, and LED bulbs we offer for the 2014 Legacy - both inside and out.

2005-2008 Subaru Legacy Forward Lighting

The fourth generation Subaru Legacy used an H7 halogen bulb for Low Beam and 9005 halogen bulbs for High Beams. Here are some details on the H7 halogen bulb:

2000 - 2004 Subaru Legacy Forward Lighting

The third generation Subaru Legacy continued to use a 9007 bulb for Low and High Beam until the 2004 model year. You can upgrade these lights with a 9007 Bi-Xenon HID Kit. The higher end GT model for 2004 was the exception and used an H1 bulb for Low Beam with 9005 bulbs for High Beam. A good choice to upgrade the Low Beam H1 bulb on the GT would be an H1 HID Kit to maximize light output. Be sure to select the 4300K color temperature if you want the brightest possible output, because there is no functional benefit in going with a higher kelvin HID kit if you're looking for the most light on the road. Higher Kelvin HID kits produce more color, but less actual useable light output. Keep this in mind when looking at upgrading your 2000, 2001, 2002, 2003, and 2004 Subaru Legacy headlights.

1995-1999 Subaru Legacy Forward Lighting

The second generation Subaru Legacy continued using an H4 bulb for both Low and High Beam. The bulb type changed to 9007 for Low and High Beam for the 1998 model year. Both H4 and 9007 are bulbs that combine both a Low and High Beam inside one bulb by using two separate filaments. They are excellent candidates for an HID conversion kit, either a Low Beam-only or Bi-Xenon kit (High and Low Beam). In a Bi-Xenon kit, the bulb physically moves position to create the High Beam lighting pattern.

1990-1994 Subaru Legacy Forward Lighting

The original Legacy in North America that started it all! 1990-1991 models used a 9004 bulb for Low and High Beam. Here are some specifications on the 9004 bulb:

  • Headlight Bulb: 9004
  • Corresponding HID Kit: 9004 HID Kit
  • Base Type: Axial Prefocus, HB1
  • Filaments: C-6/C-6
  • Bulb Length: 10.6cm (4.17”)
  • Bulb Width: 3.38cm (1.33”)
  • IEC Base: P29t
  • Color: Clear
  • Volts: 12.8/12.8
  • Amps: 5.08/3.52
  • Watts: 65/45

The lights changed to an H4 bulb for both Low and High Beam for the 1992 model year. Here are some specifications on H4 bulbs:

  • Headlight bulb: H4
  • Corresponding LED bulb: H4 LED Headlight Kit
  • Base Type: Axial Prefocus, H4
  • Filaments: C-8/C-8
  • Bulb Length: 9.2cm (3.62")
  • Bulb Width: 1.65cm (0.65")
  • IEC Base: P43t
  • Color: Clear
  • Volts: 12/12
  • Amps: 5/4.58
  • Watts: 60/55

Both of these bulb types combine the Low and High Beam inside of one bulb. If upgrading to HID, you can choose between a "Low Beam-only kit" or get an optional "Bi-Xenon upgrade" that would give both Low and High Beam functionality.
