Sidelights have simpler rules on their placement than masthead lights, and therefore this post is shorter than the last.
- The sidelights of a power-driven vessel shall be placed at a height above the hull not greater than three quarters of that of the forward masthead light.
- They shall not be so low as to be interfered with by deck lights
The sidelights, if in a combined lantern and carried on a power-driven vessel of less than 20 meters in length, shall be placed not less than 1 meter below the masthead light.
On a power-driven vessel of 20 meters or more in length:
- The sidelights shall not be placed in front of the forward masthead lights.
- They shall be placed at or near the side of the vessel
