Light chasers are electronic decorative devices which incorporate lighting effects simulating a "chasing" effect, in the form of illuminated light "dots" or "dark spots".
These electronic circuits have many light bulbs in the form of LEDs or incandescent bulbs arranged in a row or in arrays. Once switched ON the light bulbs start illuminating in sequence, one after the other.
The sequencing may happen through many different patterns depending upon the configuration of the circuit.

Usually, the sequence of shifting is from one end to the other and back, however more interesting chasing effects can be
