1999 Daihatsu Gran Move headlight bulbs: what they do and how to look after them

Headlight bulbs are absolutely relevant on the 1999 Daihatsu Gran Move. Period manufacturer service information and parts catalogues for the Gran Move/Pyzar list halogen headlamp bulbs, typically an H4 60/55W unit with a P43t base, to meet Australian Design Rules and NZ roadworthiness standards. So if the Gran Move’s headlights are dim or out, it’s the bulbs doing the hard work.

On this late-’90s Daihatsu, the headlight bulb’s job is simple but critical: provide reliable low-beam for everyday driving and a strong high-beam for open-road visibility, all while keeping the beam pattern tidy so it doesn’t dazzle oncoming traffic. Halogen H4 bulbs combine low and high beam in one globe, making servicing straightforward and affordable.

Owners will find access from the engine bay behind each headlamp. The process generally involves unplugging the three‑pin connector, peeling back the rubber dust cover, releasing the spring clip, and withdrawing the bulb. It’s worth double‑checking the handbook or a trusted parts guide for the correct spec (H4 12V 60/55W is common) and always matching left and right sides.

• Replace bulbs in pairs. Even if one’s blown, the other is often close behind, and a fresh pair keeps light output even.
• Avoid touching the glass. Skin oils create hot spots
