Patent attributes
A new portable, self-contained device for testing the full cycle of trailer light modes without additional manual actuation by the user and for identifying where and what type of specific error occurred, if any are detected. The inventive device generally comprises a compact portable housing with a fixedly attached handle and a removable housing top. Within the compact portable housing is a self-contained, rechargeable 12 volt power source to power all functionality over a sustained period of time. Also within the compact portable housing is a light mode control means that allows the device to cycle through multiple light modes for testing, and an error detection analysis means that indicates where and what type of fault is detected. The outside surface of the compact portable housing contains an on/off switch means, a light mode selector switch to select from individual light modes or a cycle mode that rotates through all light modes at a predetermined interval, and fault detection indicators to indicate when, where, and what type of fault has been detected. Attached to a side of the housing is a connection port for connecting the device to a trailer light wiring harness.
