Parts for your 2004 Toyota Land cruiser-Headlights

2004 Toyota Land Cruiser Headlights

Headlights are absolutely relevant and fitted to the 2004 Toyota Land Cruiser. This is confirmed by Toyota’s Owner’s Manual and factory repair information for the 100 Series (UZJ100/HDJ100), and by road-legal requirements such as Australian Design Rules ADR 13/00 and 46/00 and New Zealand’s Land Transport Rule: Vehicle Lighting 2004. The Land Cruiser uses dedicated low and high beams, commonly HB4 (9006) for low and HB3 (9005) for high on most Aussie and Kiwi trims, with some base models using H4 dual‑filament units.

On this rig, the headlights do the heavy lifting after dark and in poor weather—lighting the track ahead, boosting visibility to other road users, and helping the driver read the terrain when touring or towing. Proper beam aim and clean, bright lenses are crucial, whether it’s school-run duty or a long haul across the Nullarbor.

As part of regular servicing, it’s a good idea to check operation of low and high beams, indicators and park lamps, then inspect lenses for UV haze, chips and moisture. Cloudy polycarbonate can be safely restored with a quality headlight restoration kit, if there’s cracking or heavy pitting, replacement is the safer bet. Moisture or condensation usually points to a tired seal or a missing dust cap on the bulb access—sort that quickly to prevent corrosion on the terminals.

When replacing bulbs, match the correct type (HB3/HB4 or H4 depending on trim), replace in pairs for even brightness, and avoid touching the glass—skin oils create hot spots and shorten bulb life. If light output seems weak even with fresh globes, check voltage at the connectors, the headlight relay, and the relevant fuses in the engine bay junction box. After any bulb or housing change, re-aim the beams on level ground so you’re not dazzling oncoming traffic or under-lighting the verge.

For touring setups with bars, winches or driving lights, make sure wiring is tidy, fused correctly, and compliant with local rules. LED upgrades can be great, but they must be road-legal and correctly aimed. A quick headlight check at every service keeps the Land Cruiser safer, legal, and ready for dawn starts and late finishes.

• Check function and aim at each service interval.
• Clean or restore lenses, replace if cracked or leaking.
• Fit the correct bulb types, replace in pairs, keep spares in the glovebox.

Popular question: What bulb types fit a 2004 Land Cruiser 100 Series?

Most Aussie/NZ 100 Series use HB4 (9006) for low beam and HB3 (9005) for high beam. Some Standard/WorkMate trims run H4 dual‑filament bulbs. Always confirm against the vehicle’s build plate and the owner’s manual before buying.

Popular question: How do you adjust headlight aim on a 2004 Land Cruiser?

Park on level ground facing a flat wall, 3–5 metres away. Use the vertical (and where fitted, horizontal) adjusters on the headlamp backs under the bonnet. Aim the low-beam cut-off just below headlight height at the wall and ensure the hotspot is slightly to the left (for RHD markets) to avoid glare.

Popular question: Why are my headlights cloudy and how do I fix them?

UV exposure oxidises the polycarbonate lenses, turning them cloudy. A quality restoration kit will remove the oxidised layer and reseal the surface. If the lens is cracked or moisture keeps returning, replacing the housing is the long-term fix.
