Parts for your 1999 Daihatsu Gran move-Exterior bulbs

1999 Daihatsu Gran Move exterior bulbs — purpose, care and replacement

Exterior bulbs are absolutely fitted and relevant on the 1999 Daihatsu Gran Move. This is confirmed by the Daihatsu Gran Move/Pyzar Owner’s Handbook (1998–2000, Lighting section), the Daihatsu Electronic Parts Catalogue for the G30x series, and Australian/New Zealand lighting regulations (ADR 13/00 and NZTA lighting rules), all of which list and require functioning headlamps, indicators, stop/tail, reverse and number plate lamps.

On the Gran Move, exterior bulbs do the heavy lifting for safety and compliance: they light the road, make the car visible, and signal intent to other drivers. Typical fitments include H4 halogen headlamps (60/55 W) for low/high beam, small W5W park/position bulbs, PY21W or amber wedges for indicators, P21/5W for stop/tail, P21W for reverse, and 5 W bulbs for the licence plate. Some trims may have front fog lamps (often H3) or a rear fog lamp. Exact wattages can vary by market and trim, so always confirm against the handbook or the wattage and approval markings on the lamp lens.

As part of routine servicing, it’s worth doing a quick night-time walk-around to check brightness, colour and operation. Replace any blown or dim bulbs promptly, and consider changing pairs (e.g., both parkers or both tail lights) so brightness and colour match. When fitting halogen bulbs, avoid touching the glass with bare fingers—use gloves or a clean tissue to prevent hot spots that shorten bulb life. Ensure the lamp seals are seated to keep moisture out, and give connectors a clean if there’s any greenish corrosion. A light smear of silicone grease on the rubber lamp gasket helps keep water at bay, but keep lubricants off electrical contacts.

• Use ADR/E-marked bulbs with the correct wattage.
• Check fuses and earths if multiple lights are out.
• If indicators hyperflash, a bulb may be blown, for LED conversions you’ll need appropriate resistors or LED flasher gear.

If you’re seeing recurring failures, water inside a lens, or melted bulb holders, it’s time to rope in an auto sparky. Correct aim for the headlamps after any front-end work keeps you legal and ensures good night vision without dazzling others.

Popular questions

What bulb types does a 1999 Daihatsu Gran Move use?

Most Gran Move models run H4 60/55 W halogen headlamps, W5W parkers, PY21W (amber) indicators, P21/5W stop/tail, P21W reverse, and 5 W licence plate bulbs. Trims and markets differ, so verify against the vehicle’s handbook or lens markings before purchase.

Can LED bulbs be used in the Gran Move’s exterior lights?

They can be fitted in some positions, but they must meet local standards and match the original wattage/brightness and colour. Indicators may hyperflash without load resistors or an LED-compatible flasher. Headlamp LEDs may not be legal in all jurisdictions unless specifically approved for the housing.

Why are my indicators flashing fast after changing a bulb?

Hyperflashing usually means the circuit “thinks” a bulb is out. Check for a blown or wrong-wattage bulb, poor earth, or corrosion in the socket. If you’ve installed LEDs, add suitable load resistors or an LED flasher unit to restore normal flash rate.
