Parts for your 2007 Subaru Impreza-Headlight bulbs

2007 Subaru Impreza headlight-bulbs

Based on the 2007 Subaru Impreza Owner’s Manual (Lighting section) and Subaru factory service literature for the GD/GG chassis (WI/Lighting System), this model uses replaceable headlight bulbs, so headlight-bulbs are absolutely relevant to the vehicle. Most Australian and New Zealand variants were fitted with halogen reflector headlights using replaceable bulbs, some higher-spec trims may have HID (xenon) low beams, which still use a replaceable capsule.

Headlight bulbs do the heavy lifting for safe night driving, providing forward illumination and making the Impreza visible to others. Over time, halogen bulbs slowly lose brightness, so even before one fails, light output can drop off. Subaru’s servicing guidance treats bulbs as consumables—check operation at every service and renew as needed. If one’s blown, it’s smart to replace both sides so colour and brightness match.

For everyday use, quality ADR-compliant halogen bulbs are the go. If the vehicle has factory HID, use the correct spec capsule, mixing types or fitting non-compliant LEDs can lead to poor beam focus and could fail a WOF or roadworthy. Because fitment varies by trim and market (H7/H11 for low beam and HB3/9005 for high beam are common), owners should confirm the exact bulb types in the owner’s manual or on the back of the lamp cover.

• Tell-tale signs it’s time to replace: dim or yellowed output, flickering, and uneven brightness left-to-right. Also inspect the lens for haze, as cloudy lenses rob light even with new bulbs.
• Basic replacement tips: switch the lights off, open the bonnet, remove the rear lamp cover, twist the bulb holder anti-clockwise, disconnect, then install the new bulb without touching the glass. Use clean gloves and keep the rubber seal seated to keep moisture out.
• Practical access notes: on some 2007 Imprezas, moving the battery or airbox slightly improves access—have a 10 mm socket handy. No need to disconnect the battery unless moving it, if you do, maintain radio codes and settings.
• After fitting: check aim on a flat surface at night and verify both low and high beams. If output still seems weak, test the voltage at the connector and inspect earths and fuses.

As part of routine servicing in Australia and New Zealand, a quick bulb check, lens clean, and a matched pair replacement every few years keeps the 2007 Impreza’s night vision crisp and compliant.

Popular questions about 2007 Subaru Impreza headlight-bulbs

What bulb type does a 2007 Subaru Impreza use for the headlights?
It varies by trim and market. Many AU/NZ cars run halogen H7 or H11 for low beam and HB3/9005 for high beam, while some performance trims may have HID low beams. The sure-fire way is to check the owner’s manual or read the markings on the lamp cover before buying.

Why do my new bulbs seem dim on my Impreza?
Common culprits are cloudy headlight lenses, poor earth connections, low system voltage, or cheap non-compliant bulbs. Clean or restore the lenses, verify voltage at the bulb, and stick with quality ADR-compliant bulbs. Ensure the bulb is seated and the cap is sealed to prevent condensation.

Should both headlight bulbs be replaced at the same time?
Yes—halogens dim with age, so a fresh pair gives even colour and brightness and avoids another trip under the bonnet a few weeks later. It’s an inexpensive way to keep the beam pattern balanced and visibility consistent.
