FEATURES

Attwood 3-mile (4.8 km) Anchor/Masthead Lights consist of anodized aluminum poles with lightweight heads. Horizontal and vertical bases allow light pole to be adjusted and locked within a 180° arc.

Lights provide a 3-mile, 225° forward running light and 2-mile all-round anchor light. For power-driven boats boats up to 65.6 feet (20 meters). Lights meet USCG CFR 183.810, ABYC A-16 requirements, and all applicable standards as tested by Imanna Laboratory, Inc., December 17, 2003. Lights use 8-watt festoon lamp, #9230 (for 12-volt systems) or #910409 (for 24-volt systems).

CAUTION

To prevent personal injury, disconnect the power source when installing or servicing any electrical product. Remove vessel from water when using any 120 VAC power tools.

Lens can be HOT and can melt or scorch fabric. When folded down, turn light OFF and be sure lens does not touch anything.

REQUIRED FOR INSTALLATION

•Cordless drill; 1/8" and 3/8" (3 and 10mm) bits

•Marine-grade non-silicone sealant

•Phillips screwdriver

•Two #10 pan head stainless steel screws

•3-position switch (OFF/ON/ON)

•Fuse holder and fuse: 2-amp (for 12-volt systems) or 1-amp (for 24-volt systems)

•16-gauge wire

•Marine-grade wire connectors for 16-gauge wire

MOUNTING LOCATION

CAUTION

Install light so that fin (Figure 3) is TOWARD STERN and aligned on the fore/aft centerline of the vessel (within 1°). If not properly aligned, lights will not shine in required fore/aft arc.

Base must pivot on the fore/aft centerline and be mounted on a surface that allows a 360° arc of unobstructed light visibility. (Figure 1)

Bases are available for mounting on vertical or horizontal surfaces. Release the cam-lock adjustment handle to fold light or adjust to vertical position.
