Abstract
An apparatus for signalling an intended reverse operation of a mechanism having a shift lever selectively positionable in forward, neutral, and reverse positions prior to placement of the shift lever in the reverse position for effecting reverse operation. The apparatus includes an activating structure responsive to movement of the shift lever in the neutral position toward the reverse position for activating the control of a signalling device prior to reverse operation of the mechanism. The apparatus is adapted for use in signalling the back-up operation of a vehicle, such as a tractor, before the tractor starts in a reverse direction motion.

Apparatus for signalling an intended reverse operation of a mechanism having a shift lever selectively positionable in forward, neutral, and reverse positions prior to placement of the shift lever in the reverse position for effecting such reverse operation, said apparatus comprising:
- a signalling device;
- control means for operating said device to provide a warning signal;
- and activating means responsive to movement of said shift lever in the neutral position toward the reverse position for activating said control means to operate said signalling device prior to, during, and subsequent to reverse operation of the mechanism to forewarn of the reverse operation and to maintain the warning for a period of time after powered reverse operation is terminated.
