Parts for your 1999 Ford Falcon-Headlights

1999 Ford Falcon Headlights

Headlights are absolutely fitted to the 1999 Ford Falcon (AU-series). This is confirmed by the Ford AU Falcon owner’s and workshop manuals for 1998–2000 models, and is a legal requirement under Australian Design Rule 13/00 for lighting installation, with similar checks enforced by New Zealand’s Warrant of Fitness. So yes—headlights are relevant, required, and essential on any 1999 Falcon.

On this Falcon, the headlights do the obvious job of lighting the road ahead at night and in poor weather, but they’re also there so the car is clearly seen by other road users. Properly functioning low and high beams, along with parkers and indicators in the same front assemblies, help the driver spot hazards early and stay visible in traffic. If the beams are dull, hazy, or mis-aimed, both safety and compliance take a hit.

As part of routine servicing, it’s smart to give the headlights a quick once-over. Replace bulbs in pairs to keep brightness and colour matched, stick to the correct wattage specified by Ford, and avoid touching the glass of halogen bulbs with bare fingers. If the lenses are cloudy, a quality restoration kit can bring back clarity. If water or condensation is sitting inside the unit, the rear cap or seals may need attention.

• Check beam aim on a flat surface, re-aim if other drivers are flashing you.
• Clean the lenses, restore if UV haze is present.
• Inspect for moisture, cracked lenses, and perished seals or dust caps.
• Test fuses, relays, and earths if a lamp is dead before blaming the bulb.
• Replace bulbs with the correct 12V halogen type listed in the Falcon’s manual.

Typical bulb replacement steps on the AU: switch off lights, open the bonnet, pull off the rear dust cover of the headlamp, unplug the connector, release the spring clip, swap the bulb without touching the glass, refit the clip and cap, then test both beams. If upgrading, stick with ADR/NZS-compliant options. Plug-in LED/HID bulbs in halogen housings often aren’t road legal and can create glare, high-quality halogen upgrades that meet the standard are the safer bet. Keeping the Falcon’s headlights clear, correctly aimed, and electrically sound makes night driving easier and keeps it on the right side of a roadworthy or WoF check.

Popular questions about 1999 Ford Falcon headlights

What headlight bulbs fit a 1999 Ford Falcon AU?
Many AU Falcons use 12V halogen bulbs, with some variants using separate low and high-beam bulbs and others a combined dual‑filament type. The exact type is printed on the lamp or listed in the owner’s manual. When in doubt, bring the old bulb to the parts counter and match wattage (typically 55 W).

Are LED or HID conversions legal on an AU Falcon?
Only if the complete headlamp system is certified and compliant. Plug‑in LED/HID bulbs in factory halogen housings usually aren’t ADR/NZS compliant and can cause glare, risking a failed roadworthy or WoF. Stick with compliant halogen upgrades unless doing a certified retrofit.

Why is there condensation inside the headlight?
Light misting can occur with temperature changes, but standing water points to a leaking seal, missing dust cap, or blocked vent. Dry the unit out, check the rear cap and vents, and reseal as needed. If the lens is cracked or the housing is damaged, replacement is the reliable fix.
