    ### AAA Marine Combination Masthead and Halogen Deck Light for 12V Boats RWB1935

The AAA combination masthead and deck light places a clear upper light and a halogen downlight in one mast-mounted assembly. The body is made from corrosion-resistant black nylon, with a flexible plastic mounting plate intended to wrap around the mast. It is a conventional-bulb fitting for a 12V electrical system, offering two lighting functions in the same physical unit. The downward illumination can be considered when planning deck lighting around the mast, while the upper light needs separate assessment against the boat’s navigation-light requirements. Select the fitting by its actual mounting arrangement and published bulb specifications, rather than assuming it shares the approvals of another combination light.

### Choosing and using this product

Before choosing this unit, ask the supplier or a competent marine installer to confirm the upper light’s intended sector and suitability for the vessel. The published source describes the upper light as a masthead light but also gives a 180-degree figure, so that detail needs resolving before relying on it for a navigation-light installation. No compliance or visibility-distance claim is made here. Check the mast shape and the flexible plate’s fastening arrangement against the physical fitting and current instructions. Plan the cable route so it can be protected at the mast entry and accessed for servicing. Treat the upper and downward lighting functions according to the wiring instructions, and confirm how each will be controlled from the boat. Use the specified replacement bulbs and isolate the circuit before opening the lamp for maintenance. After installation, check the downward beam from the working area and verify the upper light’s orientation with the installer. Keep both lenses clean and inspect the plate, fasteners and wiring during normal mast-equipment checks. Retain the resolved specification with the boat’s lighting records so future replacement decisions are based on confirmed information.
