Parts for your 1993 Mitsubishi Pajero-Headlight bulbs

1993 Mitsubishi Pajero headlight bulbs — what they do and how to look after them

Headlight bulbs are absolutely relevant and fitted to the 1993 Mitsubishi Pajero (NH–NJ series). Technical references including the Mitsubishi Pajero Owner’s Manual for NH–NJ models (early 1990s), Gregory’s Service and Repair Manual for Pajero 1991–1997, and major bulb catalogues from OSRAM and Philips specify H4 60/55W halogen bulbs for the main headlamps on AU/NZ models. These sources align with the vehicle’s composite headlamp design rather than sealed-beam units, so a replaceable bulb is the correct setup.

On a ’93 Pajero, the headlight bulbs do the heavy lifting for safe night driving and poor-weather visibility. The common H4 bulb uses a dual filament: low beam for everyday driving and high beam for extra reach on open roads. Over time, halogen bulbs slowly dim before they fail outright, so if the lights look a bit yellow or patchy, it’s usually time to freshen them up.

There’s no fixed replacement interval, but most owners see the best results by replacing bulbs in pairs every few years or at the first sign of reduced output. Sticking with the factory 60/55W rating is recommended, going higher can overheat wiring and reflectors unless the loom has been upgraded with proper relays.

1. Pop the bonnet and disconnect the negative battery terminal for safety.
2. Reach behind the headlamp, unplug the connector and peel off the rubber dust cap.
3. Release the spring clip, remove the old bulb, and fit the new H4 without touching the glass (use gloves or the box).
4. Refit clip, dust cap, and connector, then test low and high beam.
5. Check and adjust headlight aim to spec to avoid dazzling oncoming traffic.

Handy maintenance tips: keep connectors clean and snug, inspect the dust caps so moisture doesn’t fog the lens, and make sure the earth points are tidy to avoid voltage drop. If you’re considering LED retrofits, be aware many drop-in LED bulbs aren’t road-legal in AU/NZ for housings designed for halogen, stick with quality H4 halogens that meet ADR/UNECE requirements unless you pursue a compliant conversion.

If both headlights fail together, check the relevant fuses and the headlight relay before assuming the bulbs have gone. Regularly polishing ageing lenses and verifying charging voltage will also help the Pajero’s lights punch above their weight on those long Kiwi or Aussie night runs.

What headlight bulb type fits a 1993 Mitsubishi Pajero?

Most AU/NZ NH–NJ series Pajeros use an H4 60/55W halogen bulb for the main headlamp. Always confirm by checking the old bulb markings or the vehicle handbook, and match the wattage to stay within wiring and ADR limits.

Are LED headlight bulbs legal on a 1993 Pajero?

Generally, drop-in LED replacements for halogen housings aren’t approved for on-road use in Australia and New Zealand unless the assembly is certified to the relevant standards. For road legality and proper beam pattern, stick with compliant H4 halogen bulbs or seek an approved conversion.

Why are my Pajero’s headlights still dim after new bulbs?

Common culprits include voltage drop from tired connectors or earths, cloudy lenses, and ageing reflectors. Clean grounds, inspect plugs for heat damage, polish the lenses, and consider a relay harness (with correct fusing) if voltage at the bulb is low. Ensure the alternator and battery are healthy as well.
