1. A backup alarm controller to be connected between a reverse light and a backup alarm device, comprising:
- a first circuit means for determining a number of times that the reverse light is powered within a predetermined period of time; and
a second circuit means for controlling whether the backup alarm device is powered up based on the number of times that the reverse light is powered within the predetermined period of time as determined by the first circuit means, such that if the reverse light is powered a first predetermined number of times during the predetermined period of time, the backup alarm is powered up when the reverse light is powered, and if the reverse light is powered a second predetermined number of times during the predetermined period of time, the backup alarm is not powered up when the reverse light is powered.
