Parts for your 2004 Nissan Navara-Headlight bulbs

2004 Nissan Navara headlight bulbs: what they do and how to look after them

Headlight bulbs are absolutely relevant on a 2004 Nissan Navara. The D22 Navara of this year uses replaceable halogen headlight bulbs, typically the H4 dual‑filament 12V 60/55W type with a P43t base. This is supported by Nissan’s D22 service manual (Electrical – Lighting System) and Nissan FAST parts catalog listings for the 2004 model, and aligns with ADR-required replaceable light sources for headlamps used in Australia and New Zealand. So yes, the vehicle is designed to run standard headlight bulbs, not sealed beams.

On this Navara, the headlight bulb’s job is simple but critical: provide a safe, bright, and road-legal low and high beam so the ute can be seen and the road ahead is visible. The H4 halogen setup combines low and high beam in one globe, making replacement straightforward and keeping spares easy to carry.

As part of regular servicing, it’s smart to check the headlight performance and swap bulbs in pairs. Halogens dim with age, so if one’s gone, the other’s usually not far behind. Signs it’s time to replace include a yellowish tint, uneven brightness side to side, or the high beam looking weak.

• Recommended type: H4 12V 60/55W halogen (check the handbook or bulb cap to confirm).
• Other front bulbs nearby: T10 wedge park/position bulbs (often replaced at the same time).
• Avoid “over-wattage” globes (e.g., 100/90W) unless the loom and relays are upgraded.

Replacement is a DIY-friendly job under the bonnet: unplug the connector, release the retaining spring or cap, swap the globe, refit the spring/cap, and reconnect. Don’t touch the glass—skin oils can create hot spots and shorten life. If touched, clean with isopropyl alcohol before fitting.

After fitting new bulbs, it’s worth checking headlight aim on a flat surface or having a workshop align them. Mis-aimed lights can fail a WOF/rego inspection and annoy oncoming traffic. If a bulb blows repeatedly, check the headlight fuse, earth connections, and charging voltage, over-voltage can cook globes quickly.

For Aussie and Kiwi driving, consider quality +30% to +130% performance halogens from reputable brands for better reach without straying from legal wattage. Keep a spare H4 in the glovebox—handy on a rural night run.

Popular questions

What headlight bulb does a 2004 Nissan Navara use?
Most 2004 Navara D22 models use an H4 12V 60/55W halogen globe with a P43t base for combined low/high beam. Always check the owner’s manual or the marking on the back of the headlamp to confirm, as aftermarket headlight units can differ. Park/position bulbs are typically T10 wedges.

How often should the headlight bulbs be replaced?
There’s no strict interval—replace when dim, discoloured, or failed. Many drivers see 2–4 years from a halogen, but higher-performance globes can have shorter lifespans. Replacing in pairs keeps beam colour and brightness even.

Can LED bulbs be fitted to the stock headlights?
Only if the LED retrofit is specifically designed and approved for the Navara’s reflector and complies with local ADR/NZS rules. Many generic LED retrofits cause glare and may be unroadworthy. If upgrading, use compliant kits and have the aim checked.
