Wiring diagram

This LED Medium-intensity Type B L864 Aviation

Obstruction Light flashing red color, designed for marking

top of obstacle which height is more than 45meters.

Ultra high intensity CREE LED is used for the light source

ensure the long life experience and good performance.

Self-designed reflector is used to converge light, which

could reach the standard light intensity with as less as the

power consumption.
