Parts for your 2014 Subaru Impreza-Interior bulbs

2014 Subaru Impreza interior bulbs — what they do and how to look after them

Interior bulbs are absolutely relevant on the 2014 Subaru Impreza. Technical sources — the Subaru Owner’s Manual for the model year and common industry bulb application catalogues from brands like Sylvania, Philips and Narva — all list interior lamps for this vehicle, including map, dome and cargo/boot lighting, with some trims also having glovebox and vanity mirror lamps. So yes, the Impreza runs interior bulbs from factory.

These little globes do more than make the cabin look tidy, they keep things practical and safe at night. From reading a map or finding a dropped key, to loading the boot after dark, the interior lighting helps drivers and passengers see clearly without fumbling about with a torch. The Impreza typically has front map lights, a centre dome light, a boot/cargo light, and — depending on trim — vanity mirror and glovebox bulbs.

As part of routine servicing, it’s smart to give the interior lamps a quick check. Look for dim or flickering bulbs, discoloured lenses, or moisture inside the lens. If all the interior lights stop working, a blown interior/dome fuse or a switch left in the wrong position can be the culprit, so check the cabin fuse box and the light/dimmer settings as outlined in the owner’s manual.

• Replace like-for-like: match the base type and wattage shown in the manual or a reputable bulb guide to avoid melted lenses or wiring dramas.
• Handle with care: switch the lamp off, let it cool, and use a plastic trim tool to pop the lens. Wear gloves to keep oils off the glass and to protect fingers.
• LED upgrades: a quality LED can run cooler and brighter with less current draw. Note polarity (they’re one-way), and choose CANbus-friendly designs if you notice afterglow or flicker.
• Contacts and cleanliness: if a bulb is intermittent, clean the contacts with a little electrical contact cleaner and reseat firmly.
• Battery protection: if lights stay on, check the door-activated setting and ensure all doors/boot are properly latched. The Impreza has a courtesy delay, that’s normal.

Most interior bulbs are a quick DIY job, but if a lens is stubborn, wiring looks tired, or moisture keeps returning, it’s worth getting a technician to take a look. Keep the cabin lighting sorted and the Impreza feels fresher and far more usable after dark.

FAQs

What interior bulb types does a 2014 Subaru Impreza use?

Bulb types can vary by body style and trim. Commonly, the front map and some cargo/glovebox lamps use wedge (T10/194-style) bulbs, while the centre dome often uses a festoon (around 31 mm). Vanity mirror bulbs differ by mirror style. Always confirm against the Subaru Owner’s Manual or a reputable bulb application guide to match base type and wattage.

Is it worth upgrading the Impreza’s interior bulbs to LED?

Plenty of owners go LED for brighter, whiter light, less heat and lower power draw. Choose quality LEDs to avoid flicker or afterglow, and remember polarity matters. If an LED doesn’t light, flip it 180 degrees. Some cars benefit from CANbus-friendly LEDs to prevent ghosting. Keep the wattage/fitment appropriate to protect lenses and trims.

Why do my interior lights stay on or not come on at all?

If they stay on, the switch may be set to constant ON, a door/boot may not be fully latched, or the dimmer/interior light dial could be mis-set. If nothing works, check the interior/dome fuse and the bulb itself. Persistent issues may point to a door switch fault or wiring concern, which a technician can diagnose quickly.
