Parts for your 2018 Subaru Exiga-Headlight bulbs

2018 Subaru Exiga headlight bulbs — what they do and how to look after them

Based on Subaru’s 2018 Exiga/Crossover 7 owner’s manual lighting section and Subaru FAST parts listings for the YA-series, this model uses replaceable headlight bulbs. Typical configurations are halogen H11 low beam with HB3/9005 high beam, and on some higher trims a HID (D2S) low beam with a halogen high beam. That means headlight-bulbs are absolutely relevant service items on the 2018 Subaru Exiga.

Headlight bulbs do the heavy lifting for safe night driving, providing a set beam pattern that meets ADR and NZTA requirements. On the Exiga, properly functioning bulbs keep the wide wagon’s nose lighting up the road ahead without dazzling oncoming traffic, supporting EyeSight camera performance on equipped models and helping the family arrive without drama when the weather turns.

During routine servicing, it’s smart to treat headlight bulbs as consumables. They dim before they fail, so if the lights are looking a bit yellow or uneven, it’s time for a refresh. Replace bulbs in pairs for consistent colour and brightness, and stick with quality, ADR/NZS-compliant parts. For HID-equipped trims, let the system cool, and avoid mixing capsule types—D2S is not interchangeable with other bases. With halogens, never touch the glass, skin oils create hot spots that shorten life.

Access on the Exiga is typically from the rear of the headlamp through the engine bay, some trims have tighter clearances near the battery or washer bottle. If access is cramped, removing the intake snorkel or moving the washer filler neck can help. Always reseat dust caps fully to keep moisture out, and inspect connectors for heat discolouration while you’re there.

• Signs it’s time: reduced brightness, a pink/blue tint on HID, intermittent flicker, or one side looking whiter than the other.
• Good habits: check aim after replacement, keep lenses clean and clear, and test both high and low beams before heading off.
• Legal note: retrofit LED “bulbs” in halogen housings generally aren’t road-legal in AU/NZ unless the complete headlamp is certified.

If unsure which bulb your Exiga has, check the owner’s manual, the marking on the bulb cover, or the VIN-based parts lookup. A quick check now saves a roadside headache later.

Popular questions about 2018 Subaru Exiga headlight bulbs

What headlight bulb types fit a 2018 Subaru Exiga?
Most 2018 Exiga/Crossover 7 models use H11 for low beam and HB3/9005 for high beam. Some higher trims use a D2S HID capsule for low beam with a halogen high beam. Always confirm by checking the owner’s manual, the rear cap markings, or a VIN-based parts lookup.

Are LED replacement bulbs legal for the Exiga?
In Australia and New Zealand, fitting LED “retrofit” bulbs into halogen headlamp housings is generally not road-legal unless the entire lamp assembly is certified to the relevant ADR/NZTA standards. For legal upgrades, use compliant halogen or OEM-spec HID parts, or replace the whole assembly with an approved unit.

How often should headlight bulbs be replaced?
Halogen bulbs often last 2–4 years depending on use and vibration, HID capsules can go 5–8 years but gradually lose output. Replace in pairs when output drops, there’s colour shift, or one side fails, and check headlight aim afterwards.
