Parts for your 2016 Subaru Impreza-Interior bulbs

2016 Subaru Impreza interior bulbs — purpose, care, and easy replacement

Interior bulbs are absolutely fitted to the 2016 Subaru Impreza. That’s confirmed by Subaru’s 2016 Impreza Owner’s Manual (Lighting section), the Subaru FAST parts catalogue, and Subaru Technical Information System (STIS) body-electrical service docs. You’ll find courtesy/map lamps up front, a dome light mid‑cabin, a boot/cargo lamp, plus vanity mirror and glovebox lights on most trims. So yes, “interior bulbs” are relevant for this model.

These little globes do a lot: they light the cabin when doors open, make maps and car parks easier to navigate at night, and help find gear in the boot without juggling a torch. From factory they’re typically small wedge (T10/194) or festoon‑style bulbs, chosen to balance brightness, colour, and the Impreza’s soft fade‑in/fade‑out courtesy function.

As part of routine servicing, it’s smart to check interior bulbs yearly. Incandescent bulbs dim with age and can blacken the glass long before they actually fail. If any lamp looks dull, flickers, or only comes on when tapped, it’s due for replacement. Also give the lamp lenses a quick clean, dusty lenses rob a surprising amount of light. If a whole group won’t work (say, all courtesy lamps), check the room/cabin light fuse in the interior fuse box and confirm the door‑ajar switches are operating.

Replacing bulbs is a quick DIY job on the Impreza. Use a plastic trim tool to pop the lens without scuffing the clear plastic. For halogen/incandescent types, avoid touching the glass with bare fingers, skin oils leave hot spots that shorten life. Swapping to LEDs is a popular upgrade for brighter, whiter light and lower draw—just make sure the LED size matches (wedge vs festoon) and that it’s compatible with Subaru’s dimming circuit to prevent faint after‑glow or flicker. If an LED doesn’t light, flip it around, polarity matters on many LED inserts.

• Work with the ignition off and lights switched off.
• Test new bulbs before refitting the lens.
• Choose a warm or neutral white (around 3000–4000K) for factory‑looking colour, or cool white if that’s your vibe.
• If a lamp still won’t work, inspect the holder contacts for corrosion and gently tweak for better tension.

Whether keeping things OEM or going LED, fresh interior bulbs make the 2016 Impreza feel newer, safer, and easier to live with after dark.

Popular questions about 2016 Subaru Impreza interior bulbs

What bulb types fit the interior lights on a 2016 Impreza?
Most interior positions use either small wedge (often called T10/194) or festoon bulbs around 31 mm, depending on the location (map, dome, boot, vanity, glovebox). Exact specs can vary by trim, so it’s best to confirm against the 2016 Owner’s Manual or a Subaru parts listing before buying.

Can the interior bulbs be upgraded to LED without issues?
Yes—LEDs are a common upgrade. Pick the correct base and length, and choose LEDs compatible with Subaru’s soft‑dimming courtesy circuit. Many install fine with no resistors. If you notice faint glowing after switch‑off or flicker, swap to a dimmer‑friendly LED or use a small load resistor to settle the circuit.

Why do my interior lights stay on or not come on at all?
If they stay on, check that no map light is manually left on and verify the dimmer/cabin light switch setting. A misread door‑ajar signal (including the boot latch) will also keep them lit. If nothing works, inspect the room/cabin light fuse in the interior fuse panel and look for a poor earth or bent contacts at the bulb holder.
