Parts for your 2023 Mitsubishi Asx-Headlights

2023 Mitsubishi ASX headlights — what they do and how to look after them

Headlights are absolutely relevant on the 2023 Mitsubishi ASX. Mitsubishi Motors’ MY23 ASX specifications and the Owner’s Manual list halogen projector or LED headlamps (model dependent), with auto light control and daytime running lamps on many trims—exactly what you’d expect to meet Australian Design Rules and NZ lighting requirements.

On this ASX, the headlights do the heavy lifting after dark and in poor weather, letting the driver see the road, hazards and signage while making the vehicle clearly visible to others. Low beam takes care of built-up areas without dazzling oncoming traffic, high beam helps on unlit rural roads. Auto dusk-sensing (where fitted) switches the lamps on when light levels drop, and the headlight levelling function helps keep the beam height sensible when the car’s loaded.

For halogen-equipped ASX models, bulbs are consumables. Many use H11 for low beam and HB3 (9005) for high beam, but the handbook should always be checked by VIN and trim. Replacing in pairs keeps beam colour and brightness even. When fitting new halogens, avoid touching the glass with bare fingers—skin oils can shorten bulb life. If the vehicle has factory LEDs, the headlamp is typically a sealed unit or uses an LED module, diagnosis and replacement is best left to a qualified technician to maintain cooling, sealing and beam pattern integrity.

Regular care makes a real difference. Keep lenses clean with a pH-neutral wash to avoid haze. If condensation appears inside a lamp, have the seals checked. After suspension work or a front-end knock, get the headlight aim verified. Fuses and relays live in the engine bay fuse box, a blown fuse is a quick check if a lamp won’t power up. Upgrading? Stick to ADR-compliant bulbs and avoid mismatched aftermarket LEDs that can scatter light and fail a WOF or roadworthy.

• Check operation (low/high beam, indicators, DRL) monthly.
• Replace halogen bulbs every 2–4 years or when dim/colour-shifted.
• Have LED headlamps tested and serviced professionally if output drops or faults appear.

Popular questions about 2023 Mitsubishi ASX headlights

Which bulb types does a 2023 ASX use?
Most halogen-equipped 2023 ASX variants commonly use H11 for low beam and HB3 (9005) for high beam. Upper trims may have LED headlamps with no user-replaceable bulb. Always confirm against the Owner’s Manual or a parts lookup for the specific VIN and trim.

Can the ASX headlights be upgraded to LED?
Aftermarket LED retrofit bulbs in halogen housings can create glare and may not meet ADR/WOF rules. If better performance is the goal, choose premium ADR-compliant halogen bulbs or consult a technician about approved OEM LED assemblies where available.

How do you know if the headlight aim is off?
If oncoming drivers flash you, the near-side verge isn’t illuminated, or the light pattern looks uneven on a wall test, the aim likely needs adjustment. Use the cabin levelling dial (if fitted) for load changes, and get a workshop to set aim to spec with proper equipment.
