Parts for your 1987 Suzuki Jimny-Headlight bulbs

1987 Suzuki Jimny headlight-bulbs: not applicable on factory-spec vehicles

For the 1987 Suzuki Jimny (known locally as the Sierra/SJ413), the factory headlamps in Australia and New Zealand were 7-inch round sealed-beam units, not separate headlight-bulbs/globes. That means there’s no removable bulb inside the lamp, when the light fails or performance drops off, the whole sealed-beam assembly is replaced. This setup is documented in period workshop literature for the SJ410/SJ413 and widely reflected in local repair manuals that describe the headlamp as “sealed beam” for AU/NZ models. Period parts catalogues for the SJ413 list complete 7-inch sealed-beam headlamp assemblies rather than replaceable H4 globes. These sources collectively confirm that “headlight-bulbs” are not a relevant service item for a stock 1987 Jimny/Sierra in this market.

Why no separate bulb? Sealed-beam headlamps were common in the 1980s and integrate the filament, reflector and lens in a single, sealed unit. This design is robust, simple, and was compliant with local regulations of the era. If a filament fails or the lens clouds, the correct service action is to swap the entire sealed-beam unit and then re-aim the lights. As a result, headlight-bulbs (loose globes) are not used on an original, unmodified 1987 Jimny/Sierra.

If someone’s keen on better night vision or easier future servicing, many owners retrofit 7-inch H4 headlamp housings. After conversion, standard 60/55W H4 bulbs (globes) can be used, ideally with relays to protect the switchgear and ensure full voltage at the lights. Any upgrade should be aimed correctly and remain compliant with local road rules and standards. But straight from the factory in AU/NZ, the 1987 Jimny doesn’t take a separate headlight-bulb—just sealed-beam lamps.

• Original fitment (AU/NZ): 7-inch sealed-beam headlamps (no separate bulbs)
• Service action: Replace the sealed-beam unit and check headlight aim
• Optional: Retrofit H4 housings to use replaceable headlight-bulbs (globes)

FAQs

Does a 1987 Suzuki Jimny use headlight-bulbs?
From the factory in Australia and New Zealand, no. It uses 7-inch sealed-beam headlamps, so there’s no separate bulb to replace. You swap the whole lamp if it fails or is dim, then adjust the aim.

Can I convert my 1987 Jimny to use H4 headlight-bulbs?
Yes. Fit 7-inch H4 headlamp housings, use quality 60/55W H4 globes, and add relays to reduce voltage drop and protect the switch. After installation, aim the lights properly and make sure the setup complies with local rules.

My lights are dim—what should I check on a stock 1987 Jimny?
Inspect the headlight grounds and connectors for corrosion, measure voltage at the lamp, and consider replacing aged sealed-beam units. After any replacement, re-aim the headlights. If upgrading to H4 housings, use relays and the correct wattage globes.
