Claim:
1. A device configured for installation in an existing vehicle brake light circuit having at least one brake light, a first line connected to a first side of the at least one brake light, and a severed second line connected to a second side of the at least one brake light, the device comprising: a first lead, a second lead and a third lead, the first lead configured for connection to the first line of the vehicle brake light circuit, the second lead and the third lead configured for connection to the severed second line of the vehicle brake light circuit, the first lead and the second lead defining a device output, the device output configured for connection in parallel with the at least one brake light; a control unit; and a switching member provided in a shunt path connected in parallel with the device output and controlled by the control unit, the switching member configured to operate in a first state or a second state, wherein the control unit is configured to control the switching member such that (i) a current through the shunt path is reduced when the switching member operates in the first state and thus a current through the at least one brake light is increased when the switching member operates in the first state, and (ii) the current through the shunt path is increased when the switching member operates in the second state and thus the current through the at least one brake light is reduced when the switching member operates in the second state.
