2001 Daihatsu Gran Move interior bulbs: what they do and how to look after them

Interior bulbs are absolutely used on the 2001 Daihatsu Gran Move (also known as the Pyzar). Manufacturer service literature and common parts catalogues for the M100/M110 series list replaceable bulbs for the cabin courtesy/dome lamp and the luggage/boot lamp, with some trims also having map lights. These are standard 12V incandescent bulbs, typically festoon style for the dome and wedge (T10) for smaller fittings.

Inside the Gran Move, these bulbs handle the practical stuff: lighting up the cabin when doors open, giving a quick splash of light for maps or receipts, and brightening the boot so the shopping or the footy gear doesn’t go missing. They’re simple, cheap, and designed to be serviced when they eventually burn out.

Replacing them is straightforward, but a few habits make the job cleaner and kinder to old plastics:

1. Switch the light off and remove the key, let hot bulbs cool.
2. Use a plastic trim tool to ease the lens off without marking it.
3. For a festoon bulb (dome), push it sideways out of the spring clips, for a wedge/T10 (boot or map), pull it straight out.
4. Avoid touching the glass with bare fingers, use a tissue or gloves.
5. Test the new bulb before refitting the lens. If it doesn’t light, check the bulb orientation (for LEDs), then the “ROOM/DOME” fuse in the cabin fuse box.

Bulb specs can vary by trim, so it’s smart to confirm type and wattage in the owner’s manual or a reputable parts listing. Many Gran Moves use a 31–36 mm festoon (around 8–10 W) for the dome and T10 5 W wedges for the boot or map lights. Don’t up-rate wattage, higher heat can yellow or crack lenses.

Keen on an upgrade? LED replacements run cooler, draw less current, and give a fresh, bright look. Choose warm white (around 3000–4000K) for a factory-ish colour, check polarity on wedge LEDs, and ensure the LED fits the housing so the lens clips back securely. Interior LED swaps are generally fine for road use in Aus/NZ as they don’t project light outside the vehicle.

During routine servicing, a quick check that the dome, map, and boot lights work, lenses are clean, and switches (including door jamb switches) aren’t sticky will keep the Gran Move’s cabin lighting tidy and reliable for years.

Popular questions

What bulb types fit the 2001 Daihatsu Gran Move interior lights?
Most examples take a festoon bulb for the dome/courtesy lamp (commonly 31–36 mm, ~8–10 W) and T10 wedge 5 W bulbs for the boot and any map lights. Trim and market differences exist, so always confirm against the owner’s manual or a trusted parts catalogue before buying.

If upgrading to LED, match the physical size (festoon length or T10 footprint) and choose a warm white colour for a factory look. Ensure the LED doesn’t foul the lens or reflectors.

Why do my interior lights stay on or not turn on?
If they stay on, a door switch may be sticky or the dome switch might be set to ON rather than DOOR. If they won’t turn on, check the bulb filament, the ROOM/DOME fuse, and the dimmer wheel position. Older lenses and contacts can oxidise—gently clean contacts if needed.

For intermittent issues, look at the driver’s door jamb switch and the dome lamp’s slide switch, as they see the most use.

Can the Gran Move use LED interior bulbs?
Yes. LEDs are a common upgrade and reduce heat inside the lens. They’re typically a straight swap for festoon and T10 fittings. Note LED polarity on wedge bulbs, flip them 180° if they don’t light first go. If slight glow occurs with the doors shut, choose LEDs designed for courtesy circuits.

Pick quality LEDs with appropriate brightness so the cabin isn’t blinding at night, and keep to warm white if a factory style is preferred.
