Hella Marine MST3 LED Lighthead, Amber Light, 10-30V, Self-Adhesive Mount, Selectable Flash Patterns

Overview

The Hella Marine 358111001 is an amber LED navigation and signal light for 12 to 24V DC systems. It is typically used where an amber indication is required on board, such as special-purpose signaling, marking an operating area, or showing equipment status.

Amber is not a standard port, starboard, stern, or anchor color, so it is usually fitted as an auxiliary light. Confirm the intended use for your vessel, then mount it where the lens stays visible and is not blocked by rails, rod holders, antennas, or canvas.

This is a good match for commercial and private boats that need a dedicated amber signal point and want a single light that works across both 12V and 24V electrical systems.

Key features

• Amber LED output for auxiliary signaling or marking on board
• 12 to 24V DC input range for compatibility with common marine electrical systems
• LED light source with no filament to shake loose in a vibrating hull
• Suited to installations where you want a dedicated amber indication separate from red, green, or white navigation lights
• Common fit for workboats, fishing boats, and utility setups that need an amber signal point during operations

Installation and setup

Choose a mounting surface that stays rigid underway and gives the light a clear line of sight from the direction you need. Leave enough clearance to route the wiring without sharp bends, and plan for service access so the unit can be removed later without cutting the harness.

Connect to a switched 12V or 24V DC circuit using tinned marine wire and sealed terminals. Protect the circuit with an appropriately sized fuse or breaker, keep splices above bilge level, and add chafe protection anywhere the wiring passes through fiberglass, aluminum, or bulkheads.

Compatibility and compliance

Before treating this as a navigation-related light, confirm the color and placement rules that apply to your vessel and operating area. If your intent is general signaling or equipment indication, mount it where it is noticeable without creating glare at the helm.

On-board use notes

An amber signal light can be a useful visual cue during dockside work, night operations, and gear handling, especially when you want something that stands out from standard white deck lighting. It also suits operators who want clear status indication without adding another voltage-specific part to the boat.
