Parts for your 1987 Suzuki Swift-Exterior bulbs

1987 Suzuki Swift exterior bulbs (globes): purpose, service and replacement

Exterior bulbs are absolutely fitted to the 1987 Suzuki Swift. Factory documentation for the SA/AA-series Swift/Cultus (1986–1988 Lighting/Electrical sections), Gregory’s Service and Repair Manual No. 248 (Suzuki Swift/Holden Barina 1985–1989), and market rules like Australia’s ADR lighting standards and the NZTA Warrant of Fitness lighting requirements all specify conventional 12 V incandescent exterior globes on this model. That includes headlamps, front and rear indicators, stop/tail lamps, reverse lamps, front parkers/position lamps, side markers where fitted, and the number plate lamp. LEDs weren’t standard kit in this era, so the Swift relies on serviceable filament bulbs and, in many cars, sealed-beam headlight units.

These exterior globes do the heavy lifting for safety and compliance: being seen, signalling turns and braking, and lighting the road ahead. On older cars like a ’87 Swift, keeping the lights bright and consistent helps with WOF/regos and night driving confidence, especially on darker rural roads around Australia and New Zealand.

Headlight setups vary by market and trim. Many AU/NZ 1987 Swifts (and their Holden Barina MB siblings) use 165 × 100 mm rectangular sealed-beam headlamps, replaced as a complete lamp when they fail. Some variants use replaceable halogen H4 60/55 W bulbs in composite housings. A quick look behind the headlamp will tell the story: a plug directly into a sealed glass unit means sealed-beam, a removable bulb holder with a spring clip points to H4. Stick with the specified wattage to avoid heat damage and glare.

• Check all exterior bulbs at each service or monthly—park near a wall, use reflections, and confirm brake lights with a helper.
• Replace bulbs in pairs for consistent brightness and colour.
• Handle halogen bulbs by the base only, oils on the glass shorten life.
• Clean and dry lamp housings, fix cracked lenses and perished seals to prevent moisture and corrosion.
• Inspect sockets and earth points for green crust or looseness, clean and add a dab of dielectric grease.
• If a bulb blows repeatedly, check the charging voltage and lamp earths.
• After headlamp work, verify beam aim so you don’t dazzle oncoming traffic.

Common globe specs (confirm in the owner’s guide or the lamp itself): sealed-beam rectangular headlamp or H4 60/55 W, indicators BA15s 21 W with amber lens or amber globe, stop/tail BAY15d 21/5 W, park/position W5W (T10) or BA9s 4–5 W, reverse BA15s 21 W, number plate festoon 31–36 mm 5 W. Keeping a small spare globe kit in the glovebox is a smart move for an older Swift.

Popular questions about 1987 Suzuki Swift exterior bulbs

What headlight type does a 1987 Suzuki Swift use?
Many AU/NZ cars from 1987 use rectangular sealed-beam headlights that are replaced as a full unit. Some markets and trims run composite housings with replaceable H4 60/55 W halogen bulbs. A quick peek behind the lamp will confirm which you’ve got. Always match the original spec to stay legal and avoid heat issues.

What are the common exterior bulb sizes on a 1987 Swift?
Typical fits include indicators BA15s 21 W, stop/tail BAY15d 21/5 W, parkers W5W (T10) or BA9s 4–5 W, reverse BA15s 21 W, and a 31–36 mm 5 W festoon for the number plate. Headlights are either sealed-beam rectangular units or H4 60/55 W. Check the bulb base or handbook to confirm, as there are market variations.

Why do bulbs keep blowing on an older Swift?
Common culprits are moisture in the housings, corroded sockets, poor earths, vibration from loose fittings, or high charging voltage. Dry and reseal the lamps, clean contacts, secure the housings, and have the alternator output checked. Using the correct wattage and quality bulbs also helps globe life.
