The Lightburn Zeta was an Australian Car conceived by Harold Lightburn, and built by his whitegoods company in Camden Park, Adelaide, between 1963 and 1966.

The origins of the factory (ie making washing machines) were betrayed in the final design, with a fibreglass body, almost-cardboard dashboard and a small two-stroke engine which powered the front wheels. To go in reverse, the engine was turned off, and the ignition key turned in the opposite direction to run the engine the other way. Thus one could easily do sixty miles an hour in reverse, (only 10 miles an hour slower than forwards).

Another notable feature was the front seats, which could be removed and attached to the roof. (Apparently to watch sporting events).

Even with these set-apart features, the looks of a slight-squashed milk carton, and a successful run in the 1964 Ampol Rally, the Zeta only found 363 buyers before being axed in 1966. Despite this small production run there were 3 variants - including a 500cc Roadster 'Sports'.

An early sedan can be seen at the Birdwood Museum, Adelaide.
