Parts for your 2015 Subaru Exiga-Headlight bulbs

2015 Subaru Exiga headlight bulbs: purpose, care and when to replace

Headlight bulbs are absolutely relevant and fitted to the 2015 Subaru Exiga. Subaru’s MY2015 Exiga Owner’s Manual, the Subaru FAST electronic parts catalogue, and workshop service information all list replaceable headlight light sources for this model, with trims using either halogen reflector lamps or HID (xenon) projector low beams paired with halogen high beams. So, yes—there are headlight bulbs on a 2015 Exiga, and they’re serviceable items.

On the road, those bulbs do the heavy lifting for safe night driving and poor-weather visibility. Low beam handles close and mid-range illumination without dazzling others, while high beam pushes light further down the road. Keeping the Exiga’s bulbs healthy helps it meet local roadworthy and WOF expectations, keeps night drives less stressful, and avoids last-minute fails before a trip.

There’s no fixed interval for bulb replacement, but regular checks at each service or before winter make sense. Look for dimming, colour shift (especially on HID bulbs turning pink/purple), flickering, or one side looking noticeably weaker. Replace in pairs to keep the beam colour and brightness matched. For halogen bulbs, avoid touching the glass—skin oils create hot spots and shorten life. With HID, remember there’s high voltage around the ballast, disconnect the battery and let the system discharge before any work, or leave it to a technician.

Choose the correct fitment, wattage and cap type specified on the lamp housing sticker or in the owner’s manual. Mismatched wattage can overheat the housing. If visibility has dropped but bulbs test fine, check the lens for haze and the headlight aim—aim can drift after bumps or if the vehicle’s been loaded heavily. A quick clean and a proper aim adjustment can transform night vision.

• Typical bulb life: halogen ~400–600 hours, HID often 2,000+ hours, but they fade before they fail.
• Replace both sides together for even light output.
• After fitting, verify beam pattern on a wall and adjust aim if required.

Whether the Exiga runs halogen or HID, sticking with quality OEM-spec bulbs, fitted carefully, keeps it legal, safe, and easy on the eyes during long night drives across Aussie and Kiwi roads.

Popular questions about 2015 Subaru Exiga headlight bulbs

What bulb type does a 2015 Subaru Exiga use?
It depends on trim and market. Many 2015 Exiga grades use halogen low beam (with a separate halogen high beam), while higher trims feature HID/xenon low beams with halogen high beams. The exact cap type is printed on the rear of the headlamp or listed in the owner’s manual and Subaru parts catalogue. Always match the specified type and wattage.

Can the Exiga’s halogen bulbs be upgraded to LED?
Retrofit LED capsules in halogen housings can cause glare and may not comply with ADR/NZTA requirements unless the lamp assembly is certified for LED. Beam focus can suffer too. For a legal, roadworthy result, use OEM-spec halogen or the factory HID option where fitted, or consult a specialist about compliant upgrades.

How much does replacement cost and how long does it take?
Halogen bulbs are typically affordable, and many workshops can swap them in 20–40 minutes. HID bulbs cost more and may take a little longer, especially if access is tight. It’s smart to replace in pairs and have the beam aim checked at the same time.
