Parts for your 2010 Subaru Exiga-Interior bulbs

2010 Subaru Exiga Interior Bulbs: Purpose, Care, and Easy Replacement

Interior bulbs are absolutely fitted to the 2010 Subaru Exiga. The 2010 Owner’s Manual and the Subaru YA-series Service Manual list multiple interior lamps (map/reading lights, front and rear dome lamps, luggage/boot lamp, glovebox and vanity mirror lights), with service procedures for bulb replacement. That makes interior bulbs relevant service items for this model.

The interior bulbs in a 2010 Exiga do a simple but important job: they keep the cabin usable and comfy after dark, help find gear in the boot, and make child seats, seatbelts, and maps easy to manage at night. Over time, halogen/incandescent lamps dim, yellow, or fail outright. As part of routine servicing, a quick check of all interior lighting saves frustration later—and helps avoid surprises like a stuck-on courtesy lamp draining the battery.

Common locations and typical types (may vary by trim and market—confirm in the Owner’s Manual or by inspection):

• Front map/reading lights: usually W5W/T10 wedge
• Front and rear dome lamps: often 31 mm festoon
• Luggage/boot lamp: commonly W5W/T10 wedge
• Vanity mirror and glovebox lamps: festoon or W5W, depending on trim

Quick service tips:

1. Turn the lights off and let lenses cool. For max safety, pop the negative battery terminal off if you’ll be working for a while.
2. Use a plastic trim tool to ease lenses out—avoid metal screwdrivers that can crack lenses or mark trim.
3. Note bulb orientation and match the replacement’s base and wattage. If upgrading to LED, pick quality, canbus-friendly units, check polarity (flip if they don’t light), and choose a colour temperature you like—warm white (around 3000–4300K) keeps an OEM look.
4. Wipe halogen bulbs with a clean tissue, oils from fingers can shorten life. LEDs don’t mind, but keep contacts clean.
5. Before refitting the lens, test each bulb. If a new lamp won’t light, check the fuse and switch position (door/ON/OFF).

There’s no strict replacement interval, but it’s smart to swap dim or patchy bulbs during a scheduled service. If an interior light stays on, check door switches and the lamp selector first, a simple switch setting is often the culprit. For families using the Exiga’s third row, consider a gentle LED upgrade for brighter coverage without the heat of old globes—handy on winter nights across Aus and NZ.

FAQs

What bulb sizes fit the 2010 Subaru Exiga’s interior?
Most trims use W5W (T10) wedge bulbs for map and luggage lamps, and 31 mm festoon for dome and some vanity lamps. Variations exist by market and grade, so confirm in the Owner’s Manual or remove the old bulb to match base and length.

Can the Exiga’s interior bulbs be upgraded to LED?
Yes. Quality LEDs offer brighter light and lower power draw. Choose CANBUS-friendly options, check polarity, and aim for warm white if you prefer an OEM look. Always match base type (T10 or festoon) and test before refitting the lens.

Why do my interior lights stay on and drain the battery?
Common causes include the dome switch left in ON, a sticky door-ajar switch, or a misfitted lens pressing the switch. Set lamps to DOOR, confirm all doors and the tailgate are closed, and inspect door switches. If the issue persists, check the relevant fuse and consult an auto sparky.
