This Attwood LightArmor™ 910R Series Round Plug-In Light Base is a dependable, easy to use base for an all-around pole light (sold separately). This 2-pin Light Base has a unique threaded design that provides a perfect fit with the threaded locking collar featured on Attwood Pole Lights. The innovative design ensures the pole inserts with a tight and secure fit, and it prevents rattling while the boat is underway or during trailering.
