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.

DRILLING INSTRUCTIONS

1. Remove the cover and housing by removing the Phillips-head

screw in the cover and lifting off. (See Figure 2).

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.

NOTE

Failure to make proper connections and fuse the light properly will

void the product warranty.
