Boat Light Wiring Diagram and Connection

Here, in this article, we are going to see the wiring diagram of Boat Light and the connection procedure. A boat uses different types of lights such as Navigation Lights, Anchor Light, Steaming Light, Deck Lights and Floodlights, Cabin Lights, Courtesy Lights, Underwater Lights, and so many others according to its requirement, manufacturer, etc. In this article, we will learn the connection procedure for Navigation Light and Anchor Light. Because these are the very important and essential lights for a boat and they need a special type of connection than others.

Navigation Lights: According to maritime regulations navigation lights are essential for safe boating. Navigation lights include red and green sidelights on the bow (port and starboard, respectively) and a white stern light at the rear. These lights help other vessels to determine the boat's direction and avoid potential collisions, especially during low visibility conditions or at night.

Anchor Light: When a boat is at anchor, it must display an anchor light at the highest point, typically a white light visible from all directions. The anchor light helps other vessels identify that the boat is stationary and not underway.

Wiring Diagram

Here, you can see the wiring diagram of the Anchor Light and Navigation Light and their connection with a Rocker Switch and power supply.

As we already know that when the boat is running the navigation lights should be on and when the boat is at anchor, the anchor light should be on which means we need to turn on and turn off these lights alternatively. As you see in the above wiring diagram, a DPDT rocker switch is used to achieve this alternative control.

The rocker switch has three operating positions where two positions are for ON and the rest one is for OFF. We can understand them as Up(On), Middle(Off), and Down(On). Here, the anchor light is connected to the Up and the navigation light is connected to the Down. So when the switch is pressed Upside the anchor light will be turned On and when the switch is pressed Downside the Navigation light will be turned On and when the switch keeps hold at the middle position, all the lights will be turned Off.

Connection Description

1. As we know that all the electrical loads in the boat got a power source through a circuit breaker panel. So here also the input power supply comes from the circuit breaker panel.

2. The rocker switch has a total of seven terminals. Here, terminals 2 and 5 are used for the positive input power source so they are connected to each other and finally to the positive ter, final of the power source.

3. Terminals 1 and 6 are connected to each other as they have separate contacts.

4. The positive terminal of the anchor light is connected to terminal 1.

5. The positive terminal of the navigation light is connected to terminal 3.

6. Negative terminal of both lights are connected to the negative terminal of the power source.

7. The negative terminal of the power source is also connected to terminal 7 of the switch. This provides a return path for the inbuilt indication lights of the switch.

8. The positive terminals of those inbuilt lights are already connected internally to the output terminals.
