Two Marine Lights in One Compact Housing
The Hella 8504 combines two useful lighting functions in one mast-mounted unit.
Masthead Navigation Light
The upper navigation light provides a white masthead light with a manufacturer-specified visibility range of 3 nautical miles.
It is intended for use as part of an appropriately configured navigation lighting system.
Deck Floodlight
The lower floodlight illuminates the deck and working areas of the boat.
This is particularly useful when carrying out tasks in low-light conditions, such as preparing to anchor, handling lines or working on the foredeck.
Combining both functions in one housing helps reduce the number of separate lighting fittings required on the mast.
3 Nautical Mile Masthead Navigation Light
The Hella 8504 incorporates a masthead navigation lamp designed to provide a specified visibility range of 3 nautical miles.
Correct navigation lighting is important when operating a vessel between sunset and sunrise or in conditions of restricted visibility.
The appropriate light arrangement depends on the vessel’s length, type and operating conditions.
The 8504 must be installed in the correct position and used as part of a compliant navigation lighting arrangement.
A masthead light is not the same as an all-round white anchor light.
Powerful 55W Deck Floodlight
The integrated deck floodlight uses a 12V / 55W halogen lamp to illuminate deck areas.
This makes the Hella 8504 particularly useful for sailing yachts where visibility around the foredeck, mast base and working areas is important.
Typical applications include:
● Illuminating the foredeck
● Handling anchor equipment
● Preparing mooring lines
● Working around the mast
● General deck maintenance
● Improving visibility during night-time deck operations
The floodlight is a working light and should not be used in a way that obscures required navigation lights or interferes with safe lookout.
Hella Free Form Reflector Technology
The Hella 8504 features the manufacturer’s Free Form reflector technology.
This reflector design is intended to provide effective distribution of light from the deck floodlight.
By directing illumination across useful working areas, the floodlight helps improve visibility when handling equipment aboard the boat.
It is a practical feature for sailors who regularly use their vessels in the evening or early morning.
Flexible Mast Mounting Arms
The Hella 8504 includes flexible mounting arms designed to accommodate a variety of mast profiles.
This makes the combination light suitable for a range of compatible yacht mast installations.
Before purchasing, confirm:
● Mast shape and available mounting space
● Mounting hole positions
● Cable routing
● Clearance around rigging and fittings
● Correct navigation light positioning
● Suitability of the mounting surface
Follow the manufacturer’s installation instructions and use suitable marine fasteners and wiring.
