A trailer/cargo alarm detects the proximity of trailer or cargo attached to a vehicle with an alarm system. If the trailer/cargo is moved out of proximity of the vehicle, the alarm system issues an alert. The proximity of the trailer or cargo may be detected, for example, by detecting the presence of the trailer lighting within the vehicle's electrical circuit, by dedicated hardwired sensors, or wireless detection apparatus.
