Parts for your 1989 Suzuki Swift-Tail lights

1989 Suzuki Swift tail-lights: what they do and how to keep them sorted

Tail-lights are absolutely fitted to the 1989 Suzuki Swift. The Suzuki factory literature for this era describes a rear combination lamp that includes rear position (tail) lamps, stop lamps, indicators and reverse lights. Australian Design Rules and New Zealand Warrant of Fitness inspection requirements also mandate operational rear position lamps on passenger cars of this vintage, so the ’89 Swift was built and certified with tail-lights and relies on them for road legality and safety.

On a 1989 Swift, the tail-lights sit in the rear combination assemblies and switch on with the parkers or headlights. Their job is simple but vital: make the car visible from behind at night and in low-visibility conditions, while sharing the lens with brighter stop lights for braking. They use red lenses to meet colour requirements and are designed so other road users can pick the Swift out quickly in traffic or poor weather.

Most 1989 Swifts run conventional incandescent bulbs, typically a dual‑filament 21/5W bulb (BAY15d/P21/5W) for stop/tail in each housing. Over time, bulbs dim, contacts corrode and lens seals harden, which can cause moisture inside the lamp and flaky performance. Regular checks are part of sensible servicing: if the lamps look pinkish, patchy or one side is out, it’s time for attention. Driving without working tail-lights can earn a defect notice or WoF fail, and it’s simply unsafe on Aussie and Kiwi roads.

• Inspection: With the parkers on, stand a few metres behind the car to confirm even brightness left to right. Tap the housing gently
