Parts for your 1986 Suzuki Jimny-Tail lights

1986 Suzuki Jimny tail-lights: what they do, how to look after them, and when to swap them out

Tail-lights absolutely are fitted to the 1986 Suzuki Jimny and are a critical bit of kit. The Suzuki SJ410/SJ413 (marketed as Jimny/Sierra) Factory Service Manual and the period Owner’s Manual specify rear combination lamps with tail/position and stop functions using dual‑filament bulbs, plus indicators and reverse. That lines up with the lighting requirements set out in Australian Design Rule 13/00 (installation of lighting) and the New Zealand Land Transport Rule: Vehicle Lighting 2004, both of which require rear position (tail) lamps on road‑going vehicles. So yes—tail-lights are relevant, standard, and legally required on a 1986 Suzuki Jimny.

On this classic Jimny, the tail-lights sit in the rear quarter and work as part of a combo lamp: the low‑intensity filament glows red so other drivers can see the vehicle at night or in poor weather, while the high‑intensity filament handles braking. They’re simple, tough, and easy to service—perfect for a rig that sees everything from city commutes to muddy tracks.

When servicing your 1986 Suzuki Jimny tail-lights, start with a quick visual: check for faded or cracked red lenses, moisture or dust inside the housing, and rubbed or brittle wiring near the grommets. Most Jimnys of this era use a P21/5W dual‑filament bulb (BAY15d base) for the stop/tail. If the tail works but the brake doesn’t—or vice versa—the bulb’s likely cactus or the socket contacts are dirty. Use electrical contact cleaner and a dab of dielectric grease to keep corrosion at bay, especially if the truck’s been near salt or river crossings. Always match wattage and base type to avoid heat damage or dim output, and disconnect the negative battery terminal before tinkering with the loom.

• Replace bulbs in pairs to keep brightness even left to right.
• Clean earth points on the rear body
