REQUIRED FOR INSTALLATION

•Phillips screwdriver

•Drill and bits: 3/8" for wire clearance hole

•Pilot drill for mounting screws

•Two #10 pan head stainless steel screws (not included)

LOCATION

1.Position light(s) on a surface of the gunwale or deck that is horizontal (within +/-5 degrees).

2.When installing bicolor combination light, place it on the centerline of the boat at the bow (See Figure 1a).

When installing sidelight pairs, place lights with the red lens on the port (left) and green lens on the starboard (right) as you stand onboard facing bow of the boat. Lights must be parallel to centerline of the boat (See Figure 1b).

3.Make sure there are no obstructions at the front or side (such as rail stanchions, chocks, anchors, cleats, etc.) within the light’s arc of visibility (112.5 degrees each side).

4.Measure and mark location of wire clearance hole. At the marked location(s), make a mark for a 3/8” hole. (See Figure 2).

•If installing a bicolor light, location must be on the boat centerline.

•If installing a sidelight pair, both mounting holes must be the same distance from the bow.

3.Align hole beneath light base with the position you’ve marked for the wire clearance hole. Set the lamp toward the bow and align vertical tab with the boat centerline.

4.Use the light base as a template to mark locations for the mounting screw pilot holes (use 2 #10 stainless steel screws).

CAUTION

Position holes carefully on aluminum boats so that wires do not contact the hull.

5. Drill wire clearance hole and pilot holes for the mounting screws.

MOUNTING INSTRUCTIONS

1.Be sure gasket is aligned with the base.

2.Insert two #10 stainless steel mounting screws through base and fasten base to the deck. Tighten until gasket seals to the deck.

NOTE

If area below the light will not be reachable after installation, attach a suitable length of 16-gauge red- and black-colored NON-POWERED wire that can be routed to an accessible area. Make connections according to WIRING INSTRUCTIONS below.

3.Feed the positive (red or gray) and negative (black) wires through the hole in base and lead them below deck.

4.Lower the housing onto the base. Seat the housing so the base tabs ﬁ t in the housing grooves and the base screw mount aligns with the housing screw hole.

5.Replace the stainless steel cover, then fasten it with the Phillips-head screw.

WIRING INSTRUCTIONS

The power supply must be 12-volt DC ONLY. Use crimp-type marine-grade connectors with suitable waterproof insulation. Protect all connections with suitable materials.
