CAUTION
Polarity is important. If wiring is mis-connected the LED light will
not operate.
1. Connect wires to fused power source: (See Figure 3).
Connect the (-) black wire to the negative (-) wire from the
12-volt supply.
Connect the (+) gray or red wire along with proper fuse and
switch to the positive (+) 12-volt supply.
• Fuse must be 1-amp.
2. Note that navigation rules require sidelights to be operated
separately from anchor lights. Use either two switches or a
single switch with three positions for off/anchor/running.
