Parts for your 2013 Subaru Outback-Headlight bulbs

2013 Subaru Outback headlight bulbs — what they do and how to look after them

Referencing Subaru’s 2013 Outback Owner’s Manual and Subaru Genuine Parts catalogues, this model absolutely uses replaceable headlight bulbs. The low beam is a halogen H7 in a projector housing, and the high beam is an HB3/9005 in a reflector. In many AU/NZ cars the daytime running light function uses the high beam filament at reduced power. There were no factory LED or HID headlamps fitted to AU/NZ 2013 Outback models, so headlight bulbs are definitely relevant service items.

On a 2013 Subaru Outback, the headlight bulbs are there to keep night driving safe and legal. Low beam handles close and mid-range visibility without dazzling oncoming traffic, while high beam lights up the road ahead when it’s clear. As halogen bulbs age, they dim and their colour can shift more yellow, so performance tails off before they actually fail.

As part of routine servicing, it’s smart to check the brightness and beam aim, and replace bulbs in pairs for even light output. Most owners will be fine with standard 55 W H7/HB3 halogens. Long‑life options last longer but can be a touch dimmer, high‑performance (+130%) bulbs are brighter but don’t usually last as long. LED retrofit bulbs in halogen housings may not be road‑legal in Australia or New Zealand unless specifically approved, and they can create glare, so it pays to check local rules before fitting them.

Swapping bulbs on the Outback is straightforward from the engine bay:

1. Switch everything off and let the lamps cool.
2. Remove the plastic dust cap at the rear of the lamp.
3. Release the bulb holder, unplug the connector, and take out the old bulb.
4. Avoid touching the new bulb’s glass, seat it correctly, reconnect, and refit the cap.
5. Test low and high beam, then confirm the beam aim isn’t off.

If both low beams are out, check the relevant fuses and the connectors. If output still seems weak with fresh bulbs, have the headlight aim adjusted — there are manual adjusters on the housings. There’s no fixed replacement interval, but many owners change low beams every 2–4 years depending on night driving and DRL usage.

Technical basis: Subaru 2013 Outback Owner’s Manual (lighting specifications), Subaru service information for lamp access, and Subaru Genuine Parts listings confirming H7 low beam and HB3/9005 high beam usage.

FAQs

What headlight bulb types fit a 2013 Subaru Outback?
According to Subaru’s owner’s manual and parts listings, the 2013 Outback uses H7 for low beam and HB3/9005 for high beam. On many AU/NZ cars the DRL function runs the high beam at reduced power. If you’re replacing parkers at the same time, they’re typically W5W (T10), but that’s separate from the headlight bulbs.

Can a home mechanic change the bulbs, and what are the key tips?
Yes — access is from the rear of the headlamp in the engine bay. Remove the dust cap, unclip the holder, swap the bulb, and avoid touching the glass. Fit bulbs in pairs, test both beams, and check aim afterwards. If access is tight, turning the front wheels for more room around the liner can help.

Are LED headlight bulb upgrades legal in Australia and New Zealand for this model?
Often not, unless the LED replacement is specifically approved to meet local compliance in a halogen projector. Many retrofit LEDs in halogen housings can cause glare and may not pass WOF/rego checks. If brighter light is the goal, high‑quality halogen performance bulbs are the safer, road‑legal bet.
