Parts for your 1998 Ford Falcon-Interior bulbs

1998 Ford Falcon interior bulbs — what they do and how to look after them

Interior bulbs are absolutely fitted to the 1998 Ford Falcon (AU series). Ford’s AU Falcon Owner’s Manual (1998–99, Bulb Specifications) and popular workshop references such as Gregory’s Service and Repair Manual for Ford Falcon AU (1998–2002) both list courtesy/dome, map, glovebox and luggage-compartment globes, typically in festoon and wedge styles. So yes, interior bulbs are relevant on this model.

Inside the AU Falcon, these little globes handle courtesy lighting when doors open, focused map reading at night, glovebox visibility, and boot illumination. They’re small, cheap and easy to forget—right up until someone drops a screw in the dark footwell. Keeping them working makes the cabin friendlier and safer after hours.

Most AU Falcons use festoon-type globes for the dome/courtesy lamp and wedge-type (W5W-style) globes for map and glovebox lights, with the boot usually using a festoon as well. Exact fitments vary by trim level, which is why checking the Owner’s Manual bulb chart or a reputable workshop manual is a smart move before buying replacements.

Swapping a tired globe is straightforward. Pop the lens off with a plastic trim tool, ease the old globe out, and avoid touching new halogen-style globes with bare fingers. If upgrading to LEDs, match the base type and length, and note polarity—if it doesn’t light, flip it 180 degrees. LEDs run cooler and last longer, but choose warm white if you want that factory look. And if any light won’t come on after a new globe, check the relevant interior/lighting fuse and door-ajar switches, as the AU’s body electronics rely on those inputs.

Good practice during servicing:

• Test all interior lights with doors and switches to confirm they fade and switch off correctly.
• Inspect lenses for heat haze or cracks and clean contacts if there’s flicker.
• Replace globes in pairs for consistent colour and brightness.
• If a light stays on, look to a sticky door switch or a dimmer rolled up too high before blaming the globe.

With a couple of spare globes in the glovebox and five quiet minutes, the AU Falcon’s cabin lighting stays tidy, practical and ready for late-night runs.

What interior light globes does a 1998 AU Falcon use?

According to the AU Falcon Owner’s Manual bulb chart and workshop manuals, the car uses a mix of festoon globes for the dome/boot and small wedge (W5W-style) globes for map and glovebox lights. Trim levels can vary, so it’s best to confirm lengths and wattages against the vehicle handbook before purchase.

Why do my AU Falcon interior lights stay on?

Common culprits are a door-ajar switch not signalling closed, the interior dimmer rolled to the “on” position, or a sticky map-light switch. If the globes are fine and fuses are good, have the door switches and associated wiring checked, as the AU’s body control electronics depend on those inputs.

Can I fit LED interior globes to a 1998 AU Falcon?

Yes—just match the base type (festoon or wedge) and size. Warm-white LEDs keep a factory vibe, cool white looks modern. Ensure they’re CANBUS-friendly if needed, and remember LED polarity. If an LED doesn’t light, rotate it 180 degrees.
