Suzulight was the brand used for kei cars built by the Suzuki Motor Corporation from 1955 to 1969. They were Suzuki's first entry into automotive manufacturing, having previously only produced motorcycles. The Suzulight sedans and light vans all had transversely mounted engines and front-wheel drive. The Suzulight Carry trucks and vans were the first to use the Carry label, still around today.

Kei car is the smallest category of Japanese, expressway-legal motor vehicles. 'Kei' is diminutive for kei-jidōsha,, "light automobile" or "compact automobile". With restricted dimensions and engine specifications, owners benefit firstly from lower taxes and insurance rates which lead to a lower overall cost of ownership. And in most rural areas, importantly, they were also exempted from the general Japanese shako shōmeisho (車庫証明書) parking-space ownership requirement to legally buy a motor vehicle at all, as street parking is generally restricted in Japan. Japan's carmakers also make microvans and kei trucks within this legal category.
