4. Measure and mark location of terminal clearance hole. Hole(s)
must be on boat centerline for combination sidelight (66318,
Figure 1a), or equal distance from bow for sidelight pairs (66320
and 66319, figure 1b.) Drill a ¹⁄₂" (13mm)-dia. hole. (See Figure 2.)
MOUNTING INSTRUCTIONS
1. Place base into hole and align so that light(s) shine straight
ahead. Use base to mark pilot holes for the mounting screws.
Drill pilot holes.
2. Feed the power source leads up through the deck and attach to
base terminals or wires. Insulated terminals are recommended.
3. Apply base gasket or sealant to the deck mounting area. Gasket
is highly recommended on aluminum surfaces. Place gasket, then
lens, and housing over the base.

the hull.
4. Insert mounting screws through housing and fasten into deck.

FEATURES
The Attwood 12-volt DC stainless steel one-mile navigational
sidelights are designed for mounting on horizontal surfaces, such
as the gunwale or deck. Meets USCG CFR 183.810, ABYC A-16
requirements, and all applicable standards as tested by ITS (ETL),
5/23/1995. 1 Nautical Mile visibility. Uses Lamp 9231, 12V, 8 Watt.
The housing is made of highly-polished stainless steel for corrosion
resistance. The lens completely encapsulates the bulb and socket
assembly for splash resistance. The lens rests on a rubber gasket,
making these lights virtually waterproof when used with the optional
base gasket.
REQUIRED FOR INSTALLATION
• #1 Phillips head screwdriver.
• Drill with suitable bits — ¹⁄₂" (13mm).
• Base gasket (Attwood # 910410) or marine sealant.
• Three #4 or #6 stainless steel pan head screws.
LOCATION
1. Be sure that sidelights shine straight ahead. Combination sidelight
must be aligned on centerline (See Figure 1a), sidelights pairs must
be parallel to centerline (See Figure 1b.)
2. Position light(s) on a horizontal surface (± 5°) of the gunwale or
deck. If installing a combination light, place it on the furthermost
tip of the bow on the centerline of the boat. (See Figure 1a.)
Sidelight pairs must be equal distance from the bow. The red lens
must be on the port (left) and the green on the starboard (right) as
you stand onboard facing the bow of the boat. (See Figure 1b.)
3. Ensure that there are no front or side obstructions, such as rail
stanchions, chocks, anchors, etc., within the arc of visibility
(112.5° each side).
