Parts for your 1984 Suzuki Swift-Tail lights

1984 Suzuki Swift tail-lights — what they do and how to look after them

Tail-lights are absolutely relevant and factory-fitted on the 1984 Suzuki Swift (also known in many markets as the Suzuki Cultus/SA310). This is backed by technical standards that require rear position lamps on passenger vehicles: Australian Design Rules for lighting installation, UNECE Regulations R48 (installation) and R7 (rear position/stop lamps), and New Zealand’s Land Transport Rule: Vehicle Lighting. Suzuki’s factory service literature for the mid‑1980s Cultus/Swift also lists the rear combination lamp with tail and stop functions using 12V dual‑filament bulbs. So yes—this model definitely uses tail-lights.

On a 1984 Swift, the tail-lights sit within a rear combination lamp that also houses the brake, indicator and reverse lights. Their job is simple but critical: make the car clearly visible from behind at night, in rain, or through coastal mist, with a steady red glow that other road users can pick up early. They should be bright, evenly coloured, and visible from a good distance without glare.

For routine servicing, it’s worth checking the Swift’s tail-lights every month or before a long trip. A quick walk‑around with the park lights on, and again with the brake pedal pressed (get a mate to help), will catch most issues. These cars typically use 12V P21/5W dual‑filament bulbs (BAY15d) for combined stop/tail duties—replace them in pairs so brightness matches left to right. Access is usually from inside the boot by removing the trim panel, undoing the lamp holder, and twisting the bulb out. Don’t touch new glass bulbs with bare fingers
