Parts for your 1998 Nissan Navara-Headlight bulbs

1998 Nissan Navara headlight-bulbs: what they do and how to look after them

Headlight-bulbs are absolutely relevant to a 1998 Nissan Navara (D22). Nissan’s D22 service manual for lighting, Nissan FAST parts listings, and major bulb catalogues used in Australia and New Zealand (Narva, Philips, OSRAM) all specify replaceable halogen H4 60/55W bulbs with a P43t base for the 1998 Navara’s headlamps. That means this model does not use sealed-beam units, it uses standard serviceable bulbs.

On this ute, the H4 bulb handles both low and high beam via a dual filament. Its job is simple but critical: deliver dependable forward light and a clean cutoff so the Navara meets ADR/vehicle lighting rules and keeps night driving safe on both sealed roads and rough tracks.

As bulbs age, output drops and the light goes yellow. Owners often only notice when one side fails, but a dim mate on the other side usually isn’t far behind. Best practice is to replace headlight-bulbs in pairs during routine servicing or ahead of a WoF/roadworthy. Keeping to the standard 60/55W rating helps protect the wiring and switches.

Replacement is straightforward under the bonnet: avoid touching the glass, keep the rubber dust boot seated to stop moisture, and check the 3‑pin connector for heat damage. After fitting, a quick beam-aim check against a wall is smart, especially if the ute’s carried a load or had suspension work.

• Switch lights off, open the bonnet, and reach the rear of the headlamp.
• Unplug the 3‑pin connector and peel back the rubber boot.
• Release the spring clip, withdraw the old bulb.
• Install the new H4 (P43t) with locating tabs aligned, don’t touch the glass.
• Refit the clip, boot, and connector, test low and high beam.
• Clean fingerprints with isopropyl alcohol if needed and confirm beam aim.

For upgrades, stick with reputable “+” performance halogen H4s that remain 60/55W and ADR‑compliant. LED or HID retrofits in the original halogen housing can cause glare and often aren’t legal for on‑road use in AU/NZ unless the entire headlamp assembly is approved. If bulbs fail early, check charging voltage (about 13.8–14.4V with engine running), headlamp earths, and consider heavy‑duty/long‑life H4s for corrugated routes. Keeping lenses clear and connectors clean during service helps the Navara’s lights punch above their weight on dark country roads.

Popular questions about 1998 Nissan Navara headlight-bulbs

What headlight bulb type fits a 1998 Nissan Navara?
The 1998 Navara (D22) uses H4 60/55W halogen bulbs with a P43t base. These are also commonly cross‑referenced as 9003/HB2. Always check the owner’s manual or existing bulb markings, as aftermarket headlamp assemblies may differ.

Are LED headlight bulbs legal in a 1998 Navara?
In Australia and New Zealand, LED retrofits in halogen housings typically aren’t legal for road use unless the complete headlamp assembly is certified. They can create glare and poor beam focus. For on‑road legality and reliability, use quality ADR‑compliant halogen H4s.

Why do headlight-bulbs keep blowing?
Common causes include vibration from rough roads, fingerprints on the glass creating hot spots, overvoltage from the charging system, and poor earths. Use long‑life/heavy‑duty H4s, avoid touching the glass, and have the alternator output and headlamp grounds checked.
