A drive line vibration sensor includes a mercury switch, a controller, and a warning device. The mercury switch is preferably positioned such that it is minimally affected by radial acceleration yet remains sensitive to longitudinal accelerations along the longitudinal axis of a drive line. To minimize the affect of radial acceleration, the mercury switch is attached to the drive line such that the mercury switch is tilted relative to the longitudinal axis such that the radial acceleration of the drive line does not activate the mercury switch. If the mercury switch experiences a predetermined acceleration, the controller identifies that the mercury switch is activated and the controller then awakes and activates a transmitter, such as a radio frequency (RF) transmitter to send a signal to a remote warning device such as a warning light.
