Parts for your 1986 Mitsubishi Pajero-Exterior bulbs

1986 Mitsubishi Pajero exterior bulbs

Exterior bulbs are absolutely used on the 1986 Mitsubishi Pajero. Technical sources including Mitsubishi’s Factory Service Manual for 1983–1991 Pajero (Group 54 – Chassis Electrical/Lighting), the Mitsubishi ASA electronic parts catalogue for the L040-series, and widely used workshop guides (e.g., Haynes Montero/Pajero 1983–1996) all detail headlamps, indicators, stop/tail, reverse, side-marker and number plate lamps on this model. These lamps meet period ADR/ECE lighting requirements and are essential for roadworthy/WOF checks.

The purpose of the Pajero’s exterior bulbs is straightforward: be seen and see clearly. Headlamps provide forward illumination, parkers and tail lamps mark the vehicle’s position, indicators and hazards signal intent, stop lamps warn following traffic, reverse lamps light the way when backing, and the licence plate lamp keeps the rego visible. Good bulbs aren’t just nice to have — they’re a safety and compliance must-have.

• Headlamps: market-dependent 7-inch sealed-beam units or H4 60/55W halogen replaceable bulbs.
• Front parkers/side markers: typically T10 wedge (approx. 5W).
• Indicators: commonly 21W single-filament (e.g., P21W/1156 type equivalents).
• Stop/tail: dual-filament 21/5W (e.g., P21/5W/1157 type equivalents).
• Reverse: 21W single-filament.
• Licence plate: small wedge or festoon, depending on housing.

As part of regular servicing, a quick bulb check takes minutes and saves drama at night or during a WOF/roadworthy. Keep a small assortment of spares in the glovebox, especially an H4 and a couple of 21W/5W combos if your Pajero uses replaceable types.

• Use the correct wattage — higher-watt bulbs can melt housings and won’t be ADR-compliant.
• If fitted with H4 halogen, don’t touch the glass, use clean gloves. If you do, wipe with alcohol.
• Clean and inspect sockets, a light smear of dielectric grease helps keep moisture out.
• Check earths/grounds and lens seals. Cloudy lenses or cracked seals invite corrosion.
• If your 1986 uses sealed-beam headlamps, the whole lamp unit is replaced, not just the bulb.
• After replacement, verify beam aim and indicator flash rate. Replace in pairs for even output.

Many 1986 Pajeros in AU/NZ run H4 replaceable headlamp bulbs, though some early or specific trims may have sealed beams — both are documented in the factory literature. Either way, fresh, correct-spec bulbs and tidy connections keep the old bus safe, visible and legal on any outback track or city commute.

What headlight type does a 1986 Pajero use?

Depending on market and trim, it may have 7-inch sealed beams or H4 60/55W halogen bulbs in replaceable reflectors. A quick look behind the headlamp will tell you: a three-pin plug into a removable bulb is H4, fixed lamp with wiring into the housing is sealed beam. Always match what’s fitted and stick to the specified wattage.

How often should exterior bulbs be checked on a classic Pajero?

Every few months, before long trips, and ahead of WOF/rego renewal. A two-minute walk-around with lights on — including hazards and reverse — will usually catch a failing bulb or dodgy earth before it catches you out at night.

Why do my indicators flash fast after a bulb change?

That usually means the circuit senses a lower load, often from a blown bulb, wrong wattage, or a poor earth. Confirm both bulbs on that side are working and are correct 21W types, clean the sockets and check the flasher relay if the issue persists.
