2020 Mitsubishi ASX Exterior Bulbs — Purpose, Care and Replacement

Exterior bulbs are absolutely relevant and used on the 2020 Mitsubishi ASX. Referencing the 2020 ASX Owner’s Manual for AU/NZ markets, Mitsubishi service information, and applicable Australian Design Rules for lighting (e.g., ADR 13/00, ADR 46/00), this model features a mix of user-replaceable halogen globes and long-life LED units for key functions like headlights, indicators, brake lights, reverse lights, number plate illumination and daytime running lights. Some trims use LED projector headlamps and LED combination tail lamps, while others retain halogen globes for certain positions.

On this ASX, exterior bulbs (or “globes”) do the heavy lifting for safety and visibility — helping the driver see down the road and making the vehicle clearly visible to everyone else. Indicators, stop/tail, reverse and number plate lights are simple but critical, and the car won’t pass a WOF or rego check if any are out. LEDs generally last longer and are often sealed units, whereas halogen globes are consumables that can be swapped over the driveway with basic tools.

When servicing a 2020 ASX, it pays to check all lights every 10,000 km or 6 months, or sooner if there’s a bulb-out warning, fast-flashing indicator, or dim/patchy beam. For halogen headlamps and fog lights, always handle new globes by the base (not the glass), wear gloves, and match the specified type and wattage listed in the owner’s manual. If the vehicle has LED headlamps or LED tail light modules, these are typically not user-serviceable, diagnosis and replacement are best left to a qualified technician.

• Common globe positions include: front parkers (wedge/T10), indicators (amber), fog lamps, number plate lights (wedge/T10), reverse, and stop/tail. Types can vary by trim year and market, so checking the vehicle label or manual is key.
• If a light is out, verify the fuse and holder condition, then replace the globe like-for-like. After headlamp replacement, confirm beam aim, poor aim can fail inspection and reduce night visibility.
• Avoid non-compliant “blue” or over-wattage bulbs and cheap retrofit kits. They can dazzle oncoming traffic, overheat housings, or fall foul of ADR/WOF rules.

Owners who frequently drive at night might consider quality ADR-compliant halogen upgrades on halogen-equipped trims for a clearer, whiter beam. For LED-equipped variants, keeping lenses clean and damage-free is most of the job — if an LED unit fails, book it in rather than forcing a DIY fix.

What bulb types does a 2020 ASX use?

Depending on trim, the ASX mixes LEDs (often for DRLs and some head/tail functions) with halogen globes for others. The exact types and wattages are listed in the owner’s manual and on lamp housings. Always match like-for-like or ask a technician to confirm.

Can the ASX’s LED headlamps or tail lamps be replaced at home?

LED modules are generally sealed and not designed for DIY bulb swaps. If an LED unit fails, testing and replacement should be done by a workshop to maintain beam pattern, waterproofing and compliance.

How can someone tell if it’s a blown bulb or a fuse?

A single light out usually points to a bulb. Multiple lights on the same circuit suggest a fuse. Inspect the globe filament and check the fuse diagram under the bonnet. If in doubt, have the circuit load-tested.
