1991 Nissan Primera Exterior Bulbs: what they do and how to look after them

Exterior bulbs are absolutely fitted to the 1991 Nissan Primera (P10). Technical references including the Nissan Primera P10 Owner’s Manual (1991, Lighting section), the Factory Service Manual (EL – Electrical), and the Nissan FAST parts catalogue list conventional halogen/incandescent lamps for headlights, parkers, indicators, stop/tail, reverse, fog and number plate illumination. So yes—exterior bulbs are relevant on this model, and keeping them in top nick is a simple way to stay safe and legal on Aussie and Kiwi roads.

On a ’91 Primera, exterior bulbs provide visibility after dark, signal intent to other road users, and keep the car compliant with ADR/NZTA requirements. Headlamps are typically halogen units, with small wedge bulbs for parkers and number plate lights, and filament bulbs for indicators and stop/tail functions. Because these are wear items, their brightness can fade over time long before they fully blow, so periodic checks are well worth it, especially if the car does lots of night driving or country kilometres.

Replacement is straightforward. Stick with the specified bulb types and wattages shown in the owner’s handbook or on the lamp holders—many cars of this era use H4 headlight globes, P21/5W for stop/tail, 21W amber for indicators, and T10/W5W wedges for parkers and number plate lamps, but confirm for your specific trim and market. Avoid touching halogen glass with bare fingers, use gloves or a clean tissue to prevent hot spots that shorten life. If one headlight or tail bulb fails, replacing in pairs helps keep colour and brightness matched. While you’re there, inspect lenses for haze, clean contacts, and check earth points for corrosion that can cause dim or intermittent lights. A dab of dielectric grease on connectors helps keep moisture out.

• Check all exterior lights monthly—parkers, low/high beam, indicators, hazards, brake, reverse, fog, and number plate.
• If indicators flash rapidly, a bulb may be out or the circuit needs the correct load (especially after LED swaps).
• Keep spare bulbs and a fuse puller in the glovebox for roadside fixes.
• After any bulb change, confirm headlight aim and lens seating to avoid water ingress.
• Thinking of LEDs? They can suit parkers and interior areas, but ensure road-legal specs and correct beam for headlamps, check local rules.

Rear lamp bulbs on the Primera use twist-lock holders accessible from the boot, front park/indicator bulbs are reached behind the headlamp or through the inner guard. Number plate lamps unscrew from the garnish. If bulbs keep blowing, have charging voltage checked—an overactive alternator regulator can be the culprit.

Popular questions about 1991 Nissan Primera exterior bulbs

What bulb types fit the 1991 Primera’s headlights and tail lights?
Most 1991 Primera (P10) variants commonly use H4 halogen headlight globes, P21/5W twin‑filament for stop/tail, 21W amber for indicators, and T10/W5W wedges for parkers and number plate lights. Because markets and trims vary, always confirm against the owner’s manual, the markings on your lamp holders, or the bulb chart on the fusebox cover. Matching the factory wattage prevents wiring or lens issues and keeps beam pattern and brightness where they should be.

How often should exterior bulbs be replaced?
There’s no strict interval—replace on failure or when light output noticeably fades. On older halogen setups, many owners refresh headlight globes every 2–3 years to maintain brightness, especially if doing lots of night driving. A quick monthly walk‑around to check all lights, plus carrying a small bulb kit in the glovebox, helps avoid a roadside defect notice.

Can I upgrade to LED bulbs on a 1991 Primera?
For non‑headlamp positions (parkers, number plate, some interior lights), quality LED replacements can work well. Indicators may need a compatible LED flasher relay or resistors to avoid hyper‑flash. Headlight LEDs are trickier—beam pattern, glare control and legality under ADR/NZTA rules are critical. If upgrading, choose approved products that replicate the filament position and check local regulations before fitting.
