Sea-Dog White Plastic LED Dome Light 4" Day/Night - Clear/Red Bulb

The Sea-Dog White Plastic LED Dome Light 4" Day/Night with Clear/Red Bulb (MPN 401757-1) is a dual-circuit marine cabin and deck light engineered for vibration-resistant operation in demanding saltwater and freshwater environments. Built with 15 white LEDs and 5 red LEDs, this dome light provides separate illumination modes—clear for daytime navigation and red for night vision preservation—eliminating the need for separate fixtures.

The integrated on/off/on rocker switch allows seamless switching between light circuits without rewiring. Operating at just 0.068 amps at 12 volts, this LED dome light draws minimal current, generates negligible heat, and delivers an exceptionally long service life—a critical advantage on vessels where power budgets are tight and maintenance intervals must be extended. The 4-inch diameter white plastic housing resists corrosion from salt spray and spray washdown, making it ideal for center console fishing boats, cabin cruisers, and offshore sport-fishing vessels where reliability and durability are non-negotiable.

Weekend anglers and serious offshore operators alike benefit from the red night-vision circuit, which preserves dark adaptation during nighttime fishing runs and watches. The clear circuit serves daytime cabin illumination and general deck work. Prewired and pre-switched, installation requires only 12-volt DC power connection, making retrofit straightforward on existing helm stations, cabin overhead mounts, or fish-cleaning stations. This dome light fits standard 4-inch mounting locations and is compatible with most marine electrical systems rated 12 volts DC.
