Parts for your 1997 Daihatsu Gran move-Exterior bulbs

1997 Daihatsu Gran Move exterior bulbs: what they do and how to look after them

Exterior bulbs are absolutely fitted to the 1997 Daihatsu Gran Move (also known as the Pyzar). Factory documentation and standard fitment catalogues list halogen headlamps and a spread of bayonet and wedge globes for indicators, stop/tail, reverse, number plate and side markers. That’s shown in the Daihatsu Owner’s Handbook lighting section and workshop service procedures for lamp units, as well as common fitment guides from major globe makers used in Australia and New Zealand. Therefore, exterior bulbs are relevant service items on this model (sources: Daihatsu Pyzar/Gran Move Owner’s Handbook, Lighting, Daihatsu Workshop Manual—Lighting System, Narva/Philips/Osram globe fitment catalogues).

On the Gran Move, exterior bulbs handle the essentials—seeing and being seen. Headlamps light the road, indicators and brake lights communicate intent, while tail, reverse and number plate lights keep the car legal. Typical fitments of the era include an H4 halogen headlamp globe and common types like P21W, P21/5W and W5W for the other lamps (always confirm against the vehicle’s handbook or a trusted fitment guide, as variants by market are normal).

As part of routine servicing, it’s smart to check every exterior light at least each 10,000 km or six months, and before a WoF/reg inspection. Dim, discoloured or intermittent lamps often point to a globe near end of life or an earthing issue. Replace headlamp globes in pairs so beam colour and brightness match.

• Never touch the glass of a halogen globe with bare fingers, oils shorten its life.
• Use the specified wattage—over‑watt globes can overheat housings and wiring.
• Clean hazy lenses, even a light polish can lift brightness noticeably.
• If multiple bulbs are out, check fuses and earth points before blaming the globes.
• After a headlamp change, verify beam aim to avoid glare and maintain visibility.
• Touring remote areas? Carry a spare H4 and a small assortment of P/W-series globes.

Basic replacement is straightforward. For headlamps, unplug the connector, release the spring clip, swap in the new H4, and refit the dust boot and plug. For rear lamps, remove the lamp unit screws inside the tailgate, twist out the bulb holders, replace the globe, and refit securely. If corrosion is present, clean contacts and apply a dab of dielectric grease.

Note for upgrades: LED retrofit globes in halogen housings may not be road-legal unless the complete lamp assembly is certified to applicable standards (ADR requirements in Australia, NZ Land Transport Rule: Vehicle Lighting 2004). Check local regulations before fitting.

• What bulb types are in a 1997 Daihatsu Gran Move?

  Most examples use an H4 halogen for the headlamps, with bayonet and wedge types such as P21/5W (stop/tail), P21W (indicator/reverse) and W5W for small lamps. Always verify against the vehicle handbook or a reputable globe guide, as market variations exist.

• Why do exterior bulbs keep blowing on this model?

  Common culprits are vibration, incorrect wattage, poor earths, moisture in lamp housings, or charging voltage that’s too high. Using quality ADR/NZS‑compliant globes, checking alternator output, and resealing lamp gaskets usually fixes repeat failures.

• Can the Gran Move use LED replacement globes legally?

  For exterior forward lighting, LED retrofits in halogen housings often aren’t road‑legal unless the lamp assembly is certified to the relevant ADR/NZ standards. Interior and number plate lamps can be more flexible, but always confirm with local regulations before fitting.
