At only 10mm (0.39") tall, this ultra-low machined aluminum, K-lock mounting ring base for Lopolight horizontal mounting nav lights is half the height of the standard black plastic base.
It can be used with any horizontally mounted Lopolight that comes equipped with factory installed cables. Like the standard base, this low profile base is a simple twist-lock ring, with no provisions for cables (they must be routed downward).
K-Lock is a twist-lock system that connects a horizontal mounted light and base together with a 1/4-turn.
The assembly is then secured with a stainless steel set-screw and is waterproof to 50 meters of immersion.
