Parts for your 1991 Mitsubishi Pajero-Tail lights

1991 Mitsubishi Pajero Tail-Lights: Purpose, Care, and Replacement Tips

Tail-lights are absolutely fitted to the 1991 Mitsubishi Pajero. This is confirmed by the Mitsubishi factory workshop manual and parts catalogue listings for the “rear combination lamp” assemblies, and by lighting regulations that applied in Australia and New Zealand at the time. Standards such as Australia’s ADR 13/00 (Installation of Lighting and Light-Signalling Devices) and New Zealand’s Land Transport Rule: Vehicle Lighting 2004 require operational rear position (tail) lamps on road vehicles, so the Pajero is built and certified with them from factory.

On the 1991 Pajero, the tail-lights sit in the rear quarter panels and work as part of a combined unit that also houses the brake, indicator, reverse, and number-plate lamps. Their job is simple but vital: keep the rig visible to traffic behind at night, in rain and fog, and on dusty outback tracks. Many trims use a dual‑filament bulb for tail/stop (commonly 21/5 W BAY15d), plus single‑filament bulbs for indicators and reverse. Always check the owner’s manual or the existing bulb markings before buying replacements, as variants exist across markets and trims.

Because a Pajero often cops a tougher life—towing, corrugations, beach runs—its rear lights benefit from regular checks. A quick test before a long trip or WOF/rego keeps you out of strife and avoids fines.

• Inspect lenses for cracks, fading, or water ingress. Replace cracked lenses and renew the foam gasket to keep moisture out.
• Clean bulb contacts and earth points, a light smear of dielectric grease helps prevent corrosion after river crossings or coastal use.
• Replace bulbs in pairs so brightness stays even left to right. Avoid touching glass with bare fingers.
• If a fuse keeps blowing, look for chafed trailer wiring or corroded sockets in the rear quarters and tow connector.
• Considering LEDs? Choose ADR/NZ‑compliant units and be ready to fit resistors or an LED flasher to avoid hyper‑flash and error issues.
• When refitting lamp housings, snug the screws—don’t overtighten and crack the plastic.

If a tail-light’s out on the Pajero, start with the bulb and fuse, then check the earth. The rear lamp assemblies are straightforward to remove from inside the rear quarter area, a basic screwdriver set is usually all that’s needed. Sorted lights mean safer night drives, less hassle at inspection, and a Pajero that’s ready for the next mission.

FAQs

What bulb type fits a 1991 Pajero tail-light?
Many 1991 Pajeros use a dual‑filament 21/5 W BAY15d bulb for the tail/stop function, with separate 21 W bulbs for indicators and reverse. Because trims and markets vary, confirm by checking the owner’s manual or the markings on the old bulb before purchase.

Can LED tail-light bulbs be used legally in Australia or New Zealand?
Yes, but only if the LED replacements meet local standards and don’t compromise colour, brightness, or beam pattern. You may need load resistors or an LED‑specific flasher. If unsure, have an auto sparky check compliance for WOF/rego.

Why do my Pajero’s tail-lights keep blowing fuses?
Common culprits are corroded bulb sockets, damaged earths, or a short in trailer wiring. Inspect the tow plug and loom for pinched or chafed sections, dry out any moisture in the housings, clean contacts, and replace any suspect connectors or gaskets.
