This small switch is perfect for switching between white and red illumination with standard brass bunk lights. Product details below
White/Red selectable LED lighting modules need a switch to toggle between day and night mode. Usually this switch is installed on the base of the light fixture, offset from the dimmer. There isn't a lot of extra space, so size is important. This small, durable switch is the one we use on our boat.
1/4 inch, hardware included.
