A forklift truck accessory is provided for indicating when the forks of the truck are horizontal. The accessory comprises a housing adapted to be secured relative to the generally upright mast of a forklift truck and a relatively rotatable operating member located within the housing and gravity biased towards a fixed position relative to the vertical at least within the general operating parameters of a forklift truck. Indicator means associated with the operating member give a visual indication of when the operating member is in a particular position relative to the housing, and more particularly, when the forks are horizontal.
