T-H Marine LED-51848 Recessed LED Puck Light, Red, 9 LED, 3 Inch, 12V Dimmable Boat and RV Courtesy Light

The T-H Marine LED-51848 is a 3 inch recessed LED puck light designed for cabin and compartment lighting aboard boats and RVs. It uses 9 bright red LEDs behind a clear polycarbonate lens to deliver uniform, comfortable illumination without harsh glare, making it well suited to night operation where preserving night vision matters, such as helm areas, companionways, and cockpit steps. The recessed mounting style sets the fixture flush into a 2 inch cutout for a smooth, low-profile finish with hidden fasteners, so there is no bulky housing or exposed hardware protruding from cabinetry or panels.

The circuit board is completely sealed in epoxy to resist water intrusion, corrosion, and vibration, making the light suitable for the damp, high-vibration environments found under cabinets, in rod lockers, and inside utility bins. It draws only 50mA at 12VDC, keeping power consumption low for longer battery life on house or accessory circuits, and the light is dimmable so output can be tuned for courtesy lighting or brighter task use. Each light ships with black, white, and chrome bezels so the finish can be matched to the surrounding trim, and the housing combines polycarbonate and ABS plastic with a chromed bezel for a durable, corrosion-resistant build. This is the red-LED version; the same fixture is also available with white or blue LEDs as separate part numbers.
