Parts for your 2020 Mitsubishi Asx-Headlights

2020 Mitsubishi ASX headlights

Headlights are absolutely fitted to the 2020 Mitsubishi ASX and are mandatory for road use. This is confirmed by the Mitsubishi Motors owner’s manual and model specifications for the 2020 ASX, as well as Australian Design Rules (ADR/UNECE lighting regs) and Waka Kotahi NZTA lighting requirements. So the part is relevant to this vehicle, and keeping it in top nick is a smart safety move.

The headlights on a 2020 ASX do the heavy lifting after dark and in poor weather, letting the driver see and be seen. Most AU/NZ variants run projector-style halogen low beams with halogen high beams, while some higher trims use LED units. Many models also include LED daytime running lamps to boost daytime visibility.

When it’s time for a change-out, it’s wise to replace bulbs in pairs to keep colour and brightness even. For halogen types, avoid touching the glass with bare fingers—skin oils create hot spots that shorten life. Use ADR-compliant, quality bulbs rather than off-brand “blue” specials that can underperform. If the vehicle has LED headlights, the light source may be integrated, in that case the headlamp assembly is typically replaced as a unit rather than a simple bulb swap—check the handbook for the exact setup.

After any headlight work, beam aim matters. A quick check against a wall or a proper alignment during servicing helps avoid dazzling oncoming traffic and restores full road coverage. If the beam looks patchy or weak even with new bulbs, inspect the lens and reflector: UV haze on the outer lens can be polished, but a dulled internal reflector means the lamp may need replacement.

• Keep lenses clean with car shampoo, not household abrasives.
• Consider a UV-protective sealant after polishing to slow yellowing.
• Check fuses and relays if both lights go out, the engine-bay fuse box diagram in the owner’s manual points to the right circuit.
• If moisture appears briefly after rain, that’s often normal condensation. Persistent pooling or misting suggests a failed seal—have the housing inspected.

As part of routine servicing, a workshop can test output, aim the beams, clean lenses, and confirm the correct bulb or assembly specification for the exact ASX trim—simple steps that make night driving safer and less tiring.

Popular questions about 2020 Mitsubishi ASX headlights

What bulb type does a 2020 ASX use?
Many 2020 ASX variants in Australia and New Zealand use halogen projector low beams (commonly H7) with separate halogen high beams. Some higher trims use LED headlamps where the light source is integrated. Always confirm against the vehicle handbook or the label on the lamp cover before buying parts.

How often should headlights be replaced?
There’s no set interval—replace when output drops, lenses haze, or a bulb fails. Halogen bulbs typically dim over time, so swapping both sides together keeps light balanced. If lenses have gone yellow, a professional polish and UV seal can restore clarity.

Why is there fogging inside my headlight?
A light mist after wet weather can be normal as the housing breathes, it usually clears after a drive with the lights on. If condensation lingers or there’s visible water, a vent or seal may be compromised and the assembly should be inspected for leaks.
