Parts for your 1998 Mitsubishi Pajero-Headlights

1998 Mitsubishi Pajero Headlights

Headlights are absolutely fitted to and required on the 1998 Mitsubishi Pajero. Technical references including the 1998 Pajero Owner’s Manual, the Mitsubishi workshop/service manual for the NL-series, and Australian/New Zealand regulatory standards (ADR 13/00 for lighting installation and ADR 46/00 for headlamps) all specify dipped and main-beam headlamps for this model. Most AU/NZ vehicles of this year use halogen reflector units, commonly with H4 60/55W bulbs—owners should confirm the exact bulb type in the handbook or on the lamp housing.

On a 1998 Pajero, the headlights do the core job of lighting up the road ahead and making the vehicle visible to others—crucial on country highways, unlit tracks, and changeable Kiwi and Aussie weather. Keeping them bright and correctly aimed isn’t just about compliance, it’s about safer night driving and better confidence behind the wheel.

For routine servicing, it’s worth checking the lenses for clouding or yellowing. The Pajero’s polycarbonate lenses can haze with UV exposure, a decent restoration kit and a UV sealant can bring them back, but if the coating is gone or cracks are present, replacing the assemblies is smarter. Inspect the rubber boots, connectors, and earth points under the bonnet for moisture or corrosion. A light smear of dielectric grease on terminals helps prevent gremlins. If a bulb pops, replace both sides together to keep brightness and colour matched.

Owners who’ve added a lift, a bull bar, or carry heavy loads should re-aim the beams. Tiny turns on the adjusters make a big difference—aim low beam so the cut-off sits just below the lamp centreline on a flat wall from several metres back. Avoid fitting higher-wattage or non-compliant LED/HID retrofits into halogen reflectors, they can dazzle others and won’t meet ADR requirements unless specifically approved for that housing.

Replacement is straightforward on most trims: pop the bonnet, unplug the connector, peel back the rubber boot, unclip the spring retainer, swap the bulb, and refit in reverse. Don’t touch the glass—use gloves. If both lights are out, check the fuses and headlight relay, if they’re fine, a stalk switch or ground fault may be the culprit. Finally, confirm charging voltage is in the 13.8–14.4V range so bulbs aren’t overcooked.

• Inspect lenses and aim at every service or 10,000 km.
• Use the specified bulb type and wattage, replace in pairs.
• Seal/replace perished boots and clean earths to prevent flicker.

What bulb type fits a 1998 Mitsubishi Pajero?
Most AU/NZ 1998 Pajeros run H4 60/55W halogen bulbs in reflector housings. Variations exist by trim and market, so it’s best to check the owner’s manual or the marking on the lamp. Sticking to the specified wattage avoids heat damage and stays compliant.

While LED or HID upgrades are tempting, retrofitting them into halogen reflector housings generally isn’t ADR-compliant and can cause glare. If keen on upgrades, look for E-marked/ADR-compliant complete assemblies or quality halogen +30/+50 bulbs.

How can cloudy or yellowed headlights be fixed?
Light to moderate haze usually responds well to a headlight restoration kit: sand (as directed), polish, then apply a UV sealant. This restores clarity and helps the fix last. If the lens is crazed, cracked, or the internal reflector is dull, replacement assemblies are the better call.

Also check for moisture inside the lamp. Replace torn boots and seals, and dry the housing before reassembly to stop the haze from returning.

How does one adjust the beam aim after a lift or load change?
Park on level ground several metres from a wall, with normal tyre pressures and fuel. Mark the headlamp centres on the wall, then use the adjusters so the low-beam cut-off sits slightly below and just to the left of those marks (for RHD markets). Small turns go a long way—aim for a crisp cut-off without stray glare.

If unsure, a workshop can align them quickly with a beam setter to ADR guidance, especially handy after suspension mods or if towing often.
