Parts for your 1987 Mitsubishi Pajero-Exterior bulbs

1987 Mitsubishi Pajero exterior bulbs — what they do and how to look after them

Exterior bulbs are absolutely fitted to the 1987 Mitsubishi Pajero and are relevant to routine servicing. This is supported by the Mitsubishi Pajero/Montero Factory Service Manual for the L040 series (1982–1991) lighting section and the 1987 Owner’s Handbook, both of which list replaceable globes for headlamps, indicators, stop/tail, reverse, and number plate lights. Australian Design Rules (ADR 13/00 lighting installation) also mandate exterior lighting on vehicles of this era. So, yes—this model runs conventional exterior bulbs.

On a first‑gen Pajero, exterior bulbs handle seeing and being seen: headlamps for forward illumination, parkers and side markers for presence, indicators for signalling, stop/tail lamps for braking and night driving, plus reverse and number plate lights for safety and compliance. Depending on market and trim, the headlamps are typically halogen H4 (12V 60/55W) in a replaceable‑globe housing, some markets saw sealed beams. Common secondary bulbs are usually 21W (indicators and reverse), 21/5W dual‑filament (stop/tail), and small wedge or festoon 5W (park/side/plate). Always confirm against the vehicle’s handbook or lamp markings, as variants exist.

Owners can keep lighting spot‑on with simple checks during services or before a WOF/rego: test every light, replace any dim or failed globes, and inspect wiring and earths. If a bulb pops early, corrosion in the holder or a weak earth is a usual suspect on older 4x4s. Off‑road use can invite dust and moisture, so lens seals and gaskets deserve attention.

• Replace bulbs in pairs (left/right) for even brightness, especially headlamps.
• Avoid touching halogen glass, use gloves. If touched, clean with isopropyl alcohol.
• Check and clean sockets, apply a dab of dielectric grease to deter corrosion.
• Verify headlamp aim after replacement or suspension changes to stay ADR‑friendly.
• If upgrading output, stick to correct wattage or add proper relays—don’t cook the switchgear.
• For water inside a lamp, dry it out, renew the seal, and ensure the vent isn’t blocked.

Because many 1987 Pajeros are touring rigs, carrying a small bulb kit is a no‑dramas way to stay legal out bush. For any uncertainty—sealed beam vs H4, odd trim variations—check the Owner’s Handbook or the L040 workshop manual section on lighting. That keeps the old Paj bright, compliant, and ready for night runs or the next WOF.

Popular questions about 1987 Mitsubishi Pajero exterior bulbs

What bulb types fit a 1987 Pajero?
Most Australian/NZ first‑gen Pajeros use H4 12V 60/55W headlamp globes, 21/5W for stop/tail, 21W for indicators and reverse, and 5W wedge or festoon for parkers/number plate/side markers. Some early or market‑specific models may use sealed beam headlamps, meaning the whole unit is replaced. Always confirm against the Owner’s Handbook or the markings on the lamp and socket.

Why are my indicators flashing fast after a bulb change?
Fast flash (hyper‑flash) usually means the circuit “sees” low load—commonly a blown bulb, wrong wattage globe, or an LED retrofit without a load resistor/LED‑compatible flasher. Check the front and rear indicators on both sides, verify 21W spec, and inspect earths and connectors for corrosion. If running LEDs, fit proper resistors or an LED flasher unit compatible with the Pajero’s wiring.

How can I stop moisture getting into the tail lights?
Moisture typically sneaks in via tired seals, cracked housings, or blocked vents. Remove the lamp, dry it thoroughly, replace the gasket or apply an appropriate seal, and make sure the vent path is clear. If the lens or housing is cracked, replace the assembly, otherwise moisture will return and shorten bulb life.
