The N8069 is a 3-output simulator that reproduces the effect of a flickering or defective light on its first output channel, with the remaining 2 channels being on continuously. This allows connected LEDs to be strategically placed in model signs to display this effect dramatically. It can also be used in building, streetlights, or railroad passenger cars for the same effect. How about creative placement in a back-lit building sign for a humorous effect.
