Abstract: A wireless reverse light system for trailers is provided. A transmitter is configured to replace a light bulb or an entire light assembly of at least one reverse light already contained in the vehicle configured to pull the trailer. When the vehicle or tractor is put into reverse gear, the transmitter in place of the reverse light bulb or reverse light assembly sends a wireless trigger or activation signal to a receiver light that is has been attached to a rear and/or side of the trailer. When the wireless signal is received by the receiver, it triggers the connection of a battery supply to light and/or audible indicators contained therein, thereby providing a reverse light or lights at the rear/sides of the trailer where none exist.

Abstract: A data visualisation system including a data value memory in which is maintained a finite set of data values, each data value associated with at least one time value, a display arranged to display a representation of each data value centered on respective data points, and a contour generator arranged to generate and display a contoured representation around each data point such that each data point is displayed as a local maximum. The present invention encompasses a data visualisation method and a data visualisation computer program.
