A back-up warning system for a vehicle having a back-up lighting circuit includes a license plate holder including a housing, and a proximity sensor and external audible indicator carried by the housing. The back-up warning system also includes an internal indicator for providing an internal indication of proximity to an object based upon the proximity sensor. The back-up warning system may be connected to the back-up lighting circuit so that the proximity sensor is powered and operable to detect proximity of the object adjacent the license plate holder when a reverse transmission position is selected.

A method of reducing flicker in a lamp driven by an electronic transformer in a system powered by an AC line voltage, comprising the steps of: providing current to said electronic transformer through a series connectable dimming circuit, wherein said current flows for a user selectable first conduction time in an AC line voltage half cycle; and providing a non-overlapping second conduction time in the same half cycle of the AC line voltage just prior to the next zero crossing of the AC line voltage. 11. The method of claim 10, wherein said second conduction time is a fixed amount of time. 12. The method of claim 10, wherein said fixed amount of time is about 200 microseconds. 13. The method of claim 10, wherein said second conduction time ends about 1000 microseconds before said next zero crossing of said AC line voltage. 14. A power controlling device for controlling the amount of power delivered from a source of power to a load comprising: a first and a second main terminal, said first main terminal connectable to said source of power, said second main terminal connectable to said load to allow current to flow from said source of power to said load; and a power supply that draws a power supply current from said source of power and through said load, said power supply having an efficiency greater than about 50%. 15. The power controlling device of claim 14, wherein said power supply is a switching type power supply. 16. The power controlling device of claim 15, wherein said power supply is a buck converter type switching supply. 17. The power controlling device of claim 15, wherein said power supply is a flyback type switching supply. 18. The power controlling device of claim 14, further including a controllably conductive device connected to said first main terminal and said second main terminal, wherein said power supply is operable during both times of conduction and non-conduction of said controllably conductive device. 19. The power controlling device of claim 14, wherein said power supply is constrained to run only during selected times of the AC line voltage half cycle. g a barrier at a speed determined from the pulse signal; a detector for detecting a predetermined characteristic relating to movement of the movable barrier including detecting the size of the barrier to be moved; and a controller for controlling the generation pulses in the pulse signal, the pulses of the pulse signal being controlled to vary a speed of the motor linearly from an initial speed to an adjusted speed in accordance with the detected size.
