The N8071 is configured to generate either a beacon effect (ramping up & down of brightness - the default setting), or a strobe effect for the primary (top of tower) red LED. Additionally, up to 4 more red or yellow LEDs can be connected which will run in a continuously-on state. This configuration allows this module to simulate the lighting of many different radio, cell and TV towers.

The N8071B is configured for the primary (top of tower) white LED. This is typical for towers with a strobe light at top position.
