AC Traffic Light Controller

Looking to revamp an old party traffic light or wanting to power the real thing, the AC Traffic Light Controller is the perfect solution. Accepting standard 120VAC line voltage, this controller provides over 500 Watts of power per channel and will drive full-sized LED and incandescent traffic lights (This includes all brands and wattages of dimmable LED bulbs). Solid state outputs with snubbing circuitry means both inductive and non-inductive loads can be switched effortlessly for years. No noisy mechanical relays that can fail after several months with short cycle times. Newly improved with microcontroller technology and 9 different programmable sequences. Includes quick installation instructions and four (4) adhesive standoffs for effortless mounting on virtually any surface.
