The beacon (100) has three essential components. The first is a circular base plate (200) having a raised annulus (205) around the periphery which defines an interior opening and a bottom portion (202). The second component is a dome (300) with a spherical lens having an internal concentric radial fresnel (340) and at least one reflector mirror (390). The dome (300) is mounted to the base plate (200) defines a sealed interior space protected from weather and other harmful conditions.
